There is no definitive answer to this question as it depends on what the hammer is being used for. A heavier hammer may be better for driving nails into tough materials, while a lighter hammer may be better for delicate work. Ultimately, it is up to the user to decide what weight works best for them.
A rotary hammer can be used to drill metal, but it is not the ideal tool for the job. A rotary hammer is designed for drilling into masonry and concrete, and while it can drill through metal, it is not the best tool for the job. A drill press or an impact driver is a better choice for drilling into metal.
A rotary hammer is a type of power drill that uses a hammering action to drill into concrete. The rotary action of the hammer drill produces a pounding force that breaks up the concrete and the drill bit simultaneously drills a hole into the concrete.

Wow. After first use, really impressed. My Milwaukee 2704 brushless hammer drill is like night and day in comparison. I spent more than five minutes drilling a 1/2" by 6" hole with the 2704 while hanging off the end of a rope and drilling into hard limestone. The identical hole took less than a minute to drill using the 2712 ROTARY hammer drill (same limestone, same hanging from a rope, with new drill bits for each). Using a 3.0 amp battery, the 2704 was finished after seven holes. Using the 2712, the same battery punched 20 holes.The M18 Fuel drills' ability to use the same batteries is fantastic. A normal hammer drill cannot compete with the rotary hammer's greater impact force. Although the 2712 is 3.5 lbs. heavier, I greatly prefer the side handle on the 2712. You can set it anywhere you want because it rotates 360 degrees. The 2704 can be installed on the left or right.

This one or the far more expensive Dewalt DCH273B? namely this. Purchase this drill unless you intend to do a lot of overhead drilling and want to use the hepafilter! It is significantly stronger and lighter. As a professional electrician, this drill has definitely save me hours of fumbling with cords and/or squabbling with eight other workers over the jobsite's sole cordless roto-hammer. My major issue, as expressed by another reviewer, is preventing my coworkers from borrowing it. Initially, I couldn't decide between this and the significantly more expensive small version, but I'm so happy I chose this one. It is far more compact in my luggage (the tiny version may be shorter, but it is a brick! ), significantly lighter (a big thing considering I am already hauling about well over 100lbs of tools), and substantially more powerful. So why would you buy the compact version? There are a few occasions when the compactness is useful (i.e. drilling holes for wedge anchors to anchor heavy switchgear that is already in place—the compact version can be used inside the switchgear with a bit more ease). The hepafilter is unquestionably a lifesaver if you were drilling overhead in cement all day. Depending on my employment requirements, I might still buy the tiny version in the future, but this one will be my daily carry!I should also mention that although I carry Milwaukee tools as well (love them), I gave Dewalt's rotary hammers priority due to their size and battery life.

Sandstone walls made of rocks are now starting to take shape. On sometimes, I must split rocks or remove goonies from the stones I gather (Pocono sandstone formation, fyi). I can easily drill holes with my hammer drill and a carbide drill bit for my feathers or wedges to break the stones. I can remove layers using the chisel feature or even make cuts against the grain. I can remove high points using a point and the chisel function, but I typically use my hammer and a carbide chisel from Trow and Holden for that because it's easier and gives me more control.I had my doubts about whether a rotary hammer and a carbide drill bit would work on the sandstone I work with. However, it has been highly effective. The hammer drill is holding up well after several weeks of sporadic use (I'm not a professional). Because power is available at my workplace, I decided to utilize a corded device instead of a cordless one. If I spent more time in fields, I definitely would have switched to a cordless drill, especially now that I am aware of how quickly I can drill a hole (to fit the feathers or wedges) that is 1/2" in diameter and many inches deep. With that kind of usage pattern, cordless would be perfect for me. To avoid fiddling with batteries, I currently gather my stones and transport them to a central place where I work and have access to electricity.

I read a lot of (mainly negative) reviews and examined many hammer drills. Because there were no negative reviews, this one stood out. I gambled and purchased it. In about 15 minutes, I was able to drill 4 3/8-inch-diameter holes in concrete that had been in place for 40 years. It effortlessly sliced through the concrete. Due to my inexperience, I moved slowly even though I could have completed the task twice as quickly.This is not a cheap pound-a-matic; it is a genuine rotary hammer drill. The motor never heated up. It works exactly as intended when drilling into concrete, baby. Whatever you pay for, you get. Although it was more expensive than the less expensive choices, this won't burn out or break.I'm delighted to add my five-star rating to the list. This exercise merits it.

Without the inconvenience of electrical connections, this instrument is just what I've been looking for. I've previously destroyed three or four excellent traditional corded hammer drills from Ryobi, Milwaukee, and Craftsman. Even with cautious use, it took them hours to drill relatively few holes in the concrete. What the drill doctor ordered is this DeWalt SDS tool. I would advise purchasing the SDS Plus Dust Extractor that goes with this, despite the fact that it is a significant investment. No mess, no waiting, no masks or respirators, and no cables. Just holes appear. Even if you don't need any more holes, the combination makes you want to find some brick or concrete so you can keep drilling to see if it's real or if you're dreaming. Compare prices. If you aren't a construction expert, the price on this one is a serious investment. However, you might as well just go for it even if you desire a long-term "keeper" for those projects around the house.

I occasionally need a tool similar to a hammer drill, like many homeowners, and have happily leased one for $50 per day when necessary. Recently, I worked on a three-week job that required drilling concrete and cinder blocks, chiseling concrete, cutting asphalt, driving rebar, and tamping cold-patch asphalt and crushed limestone. It's time to buy the instrument that can perform all of this, if it can be had for cheaper than the rental, because $50 times three times seven equals $1050, which is "too much."I decided that what I needed was a tool that is primarily a light-weight version of a jackhammer, with the ability to also rotate a cutting bit while hammering for specific tasks, after much Googling, reading reviews in tool magazines, talking with tech support at companies such as Bosch, Milwaukee, etc. I required a rotary hammer, not a hammer drill, because the former always hammers but also turns, while the latter always turns but also hammers (got that?).The size of the required rotary hammer needed to be determined, and after consulting experts, 1-5/8" looked to be the optimal size. As opposed to the earlier spline type chuck, which all manufacturers claimed was dead or dying, the "SDS-Max" chuck was also preferred. Most bits in the future will be available in this kind, and variable speed was also desired.The closest equivalent, at least in terms of a high-quality brand, was the Bosch model 11264EVS (no Harbor Freight Chinese tools for my shop, not anymore, thanks). By the way, Bosch makes a rotary hammer that is otherwise identical but uses spline bits. The variable speed function is indicated by the EVS suffix, however for a few dollars less, there is a model without the EVS.A spring-loaded chuck called the SDS-Max allows for one-handed tool insertion and removal. It remains in this "cocked" position if you pull back the chuck ring with one hand while holding the hammer with the other. The SDS-Max style bit's shaft is simply inserted into the chuck; as the bit's end reaches the back of the chuck, the chuck internally snaps shut on it, securing the bit to the tool. Pulling back the ring causes the bit to almost automatically come out, making it easy to remove.The hammer features two indication lamps; one illuminates when the tool is powered on (cord inserted into power source), and the other does so when maintenance is required, which often occurs when the bearings need to be replaced. If you use this every day for a living, you probably won't ever see this light turn on. Bosch offers a service for changing them when they break, which is not often.The hammer has two triggers; the top one functions as the variable speed trigger on a typical electric drill while in rotating hammer mode and starts the motor when in hammer-only mode. When in hammer-only mode, the lower trigger shuts off the motor. To be clear, in the drill (rotary hammer) mode, you squeeze and hold the top trigger, and the amount you squeeze it determines the speed. In the hammer-only mode, however, any amount of pressure on the top trigger locks the motor in 'on' at a fixed speed, eliminating the need for trigger holding, and the lower trigger turns the tool off.A variable speed knob is also present, and it is used to control the tool's top speed when the trigger is fully depressed (in rotary hammer mode only).A sizable knob to choose the mode is located on top of the hammer. The first position toggles between rotating hammer and hammer-only modes, while the middle position unlocks the chuck's rotation. When in hammer-only mode, you select the angle you want the bit fixed to using the middle position (where the hammer is not rotating the bit). When the knob is in the middle position, the bit can be rotated to 12 detents; locking the bit in that position requires moving the knob back to the hammer-only position.The hammer features two handles: a fixed handle near the chuck that has an anti-vibration shock absorber. The secondary handle can be spun anywhere about the chuck, left, right, up, down, or in between, by twisting the grip to unlock it.To make the hammer double-insulated, it appears that practically all of the structure is made of metal, with plastic used for the trim and exterior casing. Rubberized grips are used.The hammer itself is rather silent, with the majority of noise coming from the impact of the bit you are using on the object you are using it on.I purchased a tamping plate, its rod bit, a concrete chisel, an asphalt cutter chisel, and a ground rod hammer bit (which I use for sinking rebar deep into the ground). Since each of these costs around $50, they raise the hammer's price by roughly $200. The hammer is packaged in a sizable, durable plastic case. The case features compartments to hold the tool itself, a tube of oil (which is included), and a number of bits, including large ones like the tamping plate and the asphalt cutter. Most bits will likely fit in the case as well.Make sure you have a heavy-duty extension cord and an outlet on a circuit that is not also powered by something heavy, such as a refrigerator, air conditioner, etc., as the hammer consumes almost 15 amps.This tool is of the highest caliber, and you pay for it. I'm satisfied with mine.

This device makes up the majority of the light duty SDS hammer drills/chippers you see on commercial construction sites. It is amazing how much force this object possesses in relation to its weight. Because the instrument is so much smaller than you would imagine essential for that function, the first time someone handed me one to use as a chipping hammer to demo ceramic tile on a remodel, I assumed he was joking. I was astounded. This monster is unstoppable when used with either a 3" "thinnest removal bit" or a 4" Hilti style SDS scraper blade. It has great power in a little, light package, which is essential when you have to handle the object for hours on end every day at work. Not to add that it is designed to do drilling tasks rather than the "hammer drills" with Jacobs chucks that are primarily used by homeowners. Instead, it uses SDS bits. In terms of actual value versus cost, I believe I have ever purchased one of the best power tool purchases.

Edit [11/4/19]: Everything is going well. I removed an unsightly old tile wall surround and an old masonry shower pan with a 3" chisel. After making broad rectangular cuts in the slab below to access the outdated cast iron drains that needed to be replaced, the concrete was then broken into manageable pieces using an Eneacro and narrow bits. I'm so happy I bought it! Unfortunately, I have run out of oil, and even though the hammer is still functional, Eneacro has not yet replied to my inquiry regarding the appropriate grease to use. Hellooo!Just over a month after purchasing it, the hammer feature abruptly ceased working. Even though I haven't used it for as many hours as they claimed it would need, I figured I would try adding grease even though I was prepared to be angry. I inserted slightly more than half of the given tube into the top hole (nice of them to include the grease and the tool to remove the cap). I then let the drill run for around thirty seconds without trying to drill or hammer anything. The chisel barely vibrated when I tried to hammer again, but after a little while, the familiar sound of the strong hammer returned, and the chisel started to work once again!I'm sure someone at the firm has read these evaluations, so I'm hoping they'll react with advice on what grease to use when I run out, which will happen sooner than I anticipated. I have done so much with this tool in the month I've owned it, so I'm ecstatic that the lack of lubrication was the reason of the hammer's malfunction.I first used it to drill holes in CMUs (cinder blocks) so that furring strips could be fastened with Tapcon screws (2x3s were placed on their edges to allow 2" polyisocyanurate insulation board). To pilot the screws, I bought a Bosch 3/16" SDS-Plus bit. My 18-year-old Makita hammer drill had started to yell at me, but I was SO much faster.I subsequently used it to chip some uneven concrete off. It tried to remove more material than I needed to get rid of, so I had to be cautious. To easily remove glued-down linoleum flooring, I ordered a 3"x10" straight chisel from another manufacturer. Even though I haven't completed that task yet, I was aware that the broader blade would give me better control as I chipped away at high points in the concrete.After that, I drilled several 3/16" pilot holes with a rotary hammer for Tapcon screws to secure pressure-treated floor plates over concrete that was 30 years old. It took a long time to drill each hole and was the kind of labor that had probably killed my hammer drill over the years. The rotary hammer I purchased to replace the Makita was put to the test in this manner. What a fantasy! Since the ENEACRO completed each hole practically immediately, the bit didn't heat up the way the bits in the Makita did. Because they maintain a reasonably cool temperature, these parts should survive much longer.I then dug a tunnel through the firm dirt and sandstone rocks to install a drain pipe that would take water away from my foundation. Wow! afforded me far more control than a pick would have given me in breaking up the earth precisely where I wanted the trench, making the job much easier than it had been using a shovel. This chisel was excellent; a narrower one would have just buried itself and I would have spent all my time trying to get it out of the hole. It was fortunate that I couldn't find a broader chisel in SDS-Plus since if I had, I would have been better off using a full-sized SDS-Max demolition hammer on this type of dirt.After that, I broke up 5 1/2 CMUs that had been solid grouted with concrete rather than regular mortar using both the narrow chisel that came with the rotary hammer and the 3" one I purchased separately. I also used my 12" diamond blade concrete saw on some because they had rebar embedded in them. I didn't want to gouge the poured concrete that was positioned behind the blocks, so I used the hammer to cut the CMU away from it. The chisel was essential since I needed to go 8" and the saw only cuts approximately 4" deep. The hammer function ceased functioning as effectively at the conclusion of this task, and I initially assumed that the machine might have simply gotten too hot. As I mentioned in my first paragraph above, the fix was as stated.Most recently, I drilled a 4" circular hole in an unrouted CMU wall for a dryer vent. I only needed a tiny bit of hand chiseling to make the hole fit the 4" duct almost exactly and leave very little room for caulk because the smaller chisel did an absolutely flawless job of it. I simply drilled a little hole in the center of the location where a 4" hole must be from the inside, making it simple to find the hole on the outside once it stops raining (It's raining outside!). I haven't finished the outside hole yet.Do yourself a huge favor and upgrade to the ENEACRO rotary hammer if, like me, you have endured years of dealing with the shortcomings of even a heavy-duty hammer drill. It's an excellent deal on a potent tool!

Given that it is a relatively inexpensive rotary hammer drill and comes from a manufacturer I had never heard of before, I was a little hesitant to buy it. But I decided to try it nonetheless because of the price. This was intended to be a tool for homeowners only, not for professionals. I had to reposition some pier posts on a newly constructed deck. Fortunately, several of the outdated concrete piers had to be demolished in order to accommodate the new design. I removed these piers by chipping away at the really old concrete using this product. Although it took some time, the gadget did in fact finish the task. I had no problems of any type, and it seemed to have enough power. I have only used it in the hammer mode thus far, but I'm happy with the purchase. The bits and accessories are in the attractive travel case. I wish the power cord was a little bit longer and that it had variable speed, which I suppose would be more beneficial in the hammer drill mode. But overall, I'm rather content right now.**Update** 04-07-19...... So I'm still working on the deck. I drilled 38 holes with this instrument in the hammer drill mode to secure a ledger board to concrete. I was driving Red Head concrete screws that were 1/4" x 3 3/4". These holes were easy to drill thanks to this instrument. I believe I have already gotten my money's worth even if the tool breaks tomorrow.**UPDATE**07-08-19.....Just now, I raised my rating from the original 4-stars to 5-stars. I carried out my projects first replacing a retaining wall and then a fence. Once more, I had to break through the concrete around an ancient fence and support pillars. 25 or so of them. Once more, this tool was effective. Although obviously not as swiftly as a jack hammer, it was effective enough to break up and remove the old concrete from around the posts. When using as much as I have, I advise adding grease frequently because it seems to be consumed very quickly. But once more, this has far beyond my expectations.
Do rotary hammers need grease? Most rotary hammers will need some form of lubrication, whether it be grease or oil. However, before applying any lubricant, be sure to check your owner’s manual to see if there are any specific instructions. Generally speaking, though, grease is the best lubricant to use on a rotary hammer.
There are a few things to consider when purchasing a rotary hammer. First, decide what the tool will be used for. Second, consider the size and power of the tool. Third, think about the budget. After deciding what the tool will be used for, research what size and power is best suited for the task. If the rotary hammer will be used for light duty tasks, a smaller tool may be all that is needed. If the rotary hammer will be used for more heavy duty tasks, a larger and more powerful tool will be necessary. Once
There are a few key factors that you need to consider when trying to decide if a rotary hammer or a hammer drill is better for you. The first is the type of material you will be working with. If you are working with softer materials, then a hammer drill is going to be the better option. However, if you are working with harder materials, then a rotary hammer is going to be the better choice. The second factor is the size of the job. If you are only working on a small area, then a hammer drill is going to be the better option. However
A rotary hammer is a worth it power tool if you need to do a lot of drilling, especially in masonry or concrete. It can also be used for chiseling and breaking up material. The hammer function on a rotary hammer makes it easier to drill through tougher materials.
A rotary hammer is a power tool that can create holes in concrete and drive in nails. It uses a hammering action to drill through materials. Rotary hammers are used for a variety of tasks, such as breaking up concrete, driving nails, and removing tile.
SDS drill stands for "self-drilling screw." This type of screw is designed to drill its own hole as it is being driven into the material. It is often used in applications where a pre-drilled hole is not available, or where the material is too hard to drill a hole into using a traditional drill bit.
