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

Installing new floors and had to remove the old tiles. Our standalone "pantry cabinet" in the kitchen was installed over the existing tile (not sure why they did that). I used with my Craftsman 4 1/2 angel grinder and the smooth continuous blade to cut the protruding tiles off at the base of the cabinet. It worked like a charm! I also used it to do the same for the bay window bench that was installed over the existing tile floor. All in all I dry-cut about 15 tiles with no issues or dulling of the blade. Very pleased with the price and product. Have not used the other 2 blades yet, but if the others are like the first blade, they will be a nice added bonus.

I used these in a cordless angle grinder for cutting a bunch of concrete pavers as well as cleaning up some edges on a concrete driveway. They worked great and didn't appear to dull or become less effective as I went. The build quality appeared to be good, which is a concern when putting anything into an angle grinder. I've used two of the three blades, and have had no issues so far.

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.

All I heard from the YouTube "pros" was to buy expensive blades! And I did get well known brands like Makita to have them as spares when these cheap blades went dull after few cuts (according to the YouTube "pros") spent about 80$ on blades at Home depot. Well, I only put 1 disc on my Bosch 18V grinder and completed the entire wall cutting 1/2 inch thick natural stone. Made over 100 cuts and adjustments. The blade held sharp and did not dull at all. From cut 1 to cut 100+ the cutting speed did not change! I cut dry. No water. Buy with confidence! You will not be disappointed! And no im not promoting them or anything like that. I'm just a DIY from NJ..

I liked having a variety of 3 blades to choose from. For first time users like me I would have liked a little user information sheet explaining what each blade is best used for rather than trial and error using one at a time. As best as I can tell, the notched blade is best for hogging down more material faster, the grooved blade is for medium, finer removal, and the smooth edged blade is best for clean, end work. They all do the job, and do it quickly however. In about one hour I cut down about 10' of the edge of a 2" root-raised patio slab trip hazard. For my finish, smoothing work I got a OCR grinding cub wheel.

I used two of the three. The one I used to cut into a cement slab that was binding. Like butter compared to the grinding wheels I had used. The other made quick work of a couple cinder blocks and some stepping stones. No problems Thai I could see. Just great little cutting wheels!!!

I’m not sure if I over used it in the first two days doing tile but I had one crack all the way through and I’m afraid to use it anymore. I just tossed it and haven’t had a problem with the other two.

This was second order of these blades. We used it to cut concrete filled imatation stone for the outside of a house. We had to cut irregular shaped rocks often so they would fit into limited space. They cut well and were used daily. A great value.

Works very well

I used these to cut flagstone with an angle grinder. For my use, the slotted cutter worked great, cut smoothly, and kept on cutting even after it looked like most of the abrasive had worn away. The other blades tended to bind, and the grinder would heat up. They wore out quickly. To be fair, I'm cutting a lot of stone, and cutting curves, which is tough on the blades. Wish they would offer a three-pack of just the slotted cutters!

Work great!

Good quality
