Best Diamond Saw Blades in 2020

DEWALT DW4725 High Performance 4-1/2-Inch Dry Cutting Continuous Rim Diamond Saw Blade with 7/8-Inch Arbor for Masonry Review:

 This little diamond blade is great. It cuts through concrete pavers like they aren't even there. Furthermore, because of its small size, one can get pretty surgical with it. After I had got my technique down, I was cutting curves and then using the edge of the blade to add a little bevel. I know, not what it's meant for but it worked.

A couple things to consider. It's really obvious when you think about, but escaped me when purchasing. With the grinder's guard/body in the way, you're only going to get about an inch of cut depth. My real quick mental math went something like this: 4-1/2" blade means a 2-1/4" cut depth. But it really doesn't.

Secondly, this thing generates massive amounts of dust. I'm assuming most people don't want silicosis, so consider a respirator pretty much mandatory.

Would definitely purchase again!

ROK 4-1/2 inch Diamond Saw Blade Set, Pack of 3 Review:

For the price, this set of three blades is a bargain.
I needed a continuous blade to cut some ceramic tile. The blade worked well enough.
I used the included size adapters so the blades would fit the 5/8-inch shaft of my grinder. The adapters pressed easily into the center hole with just thumb pressure on all three blades. Compared to another blade I was using at the same time, the fit of these adapters was looser. Adapters fell off the blades that were not in use. With the other blade I was using, not from this set, I had to work a little more to press in the adapter, and it never fell off when the blade was dismounted.

The price is fantastic. If you have a little work to do, this set is a good deal. Or, if you want to make sure your grinder has a variety of blades for whatever comes along, this is a good buy. You'll be ready.

If your grinder has a 7/8-inch shaft so you don't need an adapter, they may work more smoothly. They DO cut. No question about it.

Peakit Tile Cutter Blade 4.5 Inch Porcelain Diamond Blade Ceramic Cutting Disc Wheel for Angle Grinder, Reversible Color Review:

This diamond disc has worked very well for cutting porcelain tiles in straight or curved shapes so far. I am not a professional tile mechanic or contractor, but this disc has been invaluable in my renovation of a bathroom, (re-tiling floor, walls, and shower stall). My only complaint is the blue color transferred to tiles when using the side to bullnose cut tile edges.

GoYonder 4.5 Inch Super Thin Diamond Saw Blade for Cutting Porcelain Tiles,Granite Marble Ceramics (4.5") Review:

Need to cut my granite counter top from 30" to 36". After watching YouTube video, I found this blade here with a low price. Wondering if it can do the job and since this is a one time project, I decided to purchase it anyway. It arrived 1 day latter than it was promise and I was pretty upset since I have friend coming over to help. When it finally arrived, I was by myself but decided to do it. I could not believe how easy it cut 1.5" thick granite. I was going about 1" every 3 seconds and it has no problem doing it with a nice edge.
Strongly recommending it. Such a good product!!!

Supper Thin Diamond Tile Blade Porcelain Saw Blade for Cutting Porcelain Tile Granite Marbles (4") Review:

I made a mistake and ordered a quartz backsplash for my bathroom 3/4 of an inch too long. Quartz is harder than marble or granite and I was seriously worried about my ability to cut it. I've got a cheap tile wet saw, but this blade did a great job. I used it today for the first time so I don't know how durable it is but it is a great value and it did the trick.

AUTOTOOLHOME 4.5" Diamond Blade Angle Grinder Dry Cutting Wheel Grinding Stone Brick Concrete Ceramic Tile Cut off Wheels Disc Review:

Tiled a whole kitchen using this. All the cuts are that are covered by trim were made with this blade instead of a wet saw. It's messy. I used a tile cutter for end cuts on 24"X12" tile but the length cuts and all the cuts around four doorways and even a couple of circular cuts around plumbing I quickly made with this. It appears to have plenty of life left in it. Be sure to wear ear, eye and breathing protection. You do not want a chip in your eye or a lung full of dust.

QEP 6-7006GLQ 7-Inch Continuous Rim Glass Tile Diamond Blade, 7mm Rim Height, 5/8-Inch Arbor, Wet Cutting, 8730 Max RPM Review:

This is THE blade for glass at an affordable price. I had a regular tile saw blade that ate glass tile. You have to go slow with it and be patient in cutting. I get a better edge with the tile facing down. Also, tape any tile sheet that has small pieces, like rods, so they don't go flying off. It's also better to have this sanding pad to clean up any rough spots: GP15101 Diamond Hand Sanding Pad for Sanding, Grinding, Polishing and Sharp Edges / for Glass, Stone, Marble, Concrete / A+ Class / GRIT 400 - Fine
