Diamond Beveling Chamfer Bit 2" (50mm) Porcelain Ceramic Tile Cutter with Core Drill Bit Hex Shank Adapter for Diamond Hole Saw Enlarging Trimming Polishing Shaping Existing Holes

Needed to install 3/4" electrical conduit though a concrete block wall. Worked ok but slow with a regular drill but then switched to my hammer drill and made short work of boring through the concrete block wall. Better value than in the local big box stores. Since I needed to drill from just one side of the wall, I bought a Milwaukee 12 in. Alloy Steel Drill Bit Extension 3/8 in. Hex Shank that worked fantastic even though I did have to hammer in the drill bit / hole saw to get it to fit - was a very tight fit.

Well made, great for thicker countertops. My husband only cut one slab so we can't comment on the longevity but the diamond coating looks brand new after he made the first cut. A 2 inch chamfer bit is included too and it came very handy at the end with no sign of wear on the diamond part either. Great set, great price.

I used this to bore a hole through a quartz countertop for a soap dispenser install. It worked very well. I used my angle grinder, which has variable speed settings. I kept the speed on the low side and just like the grinder and but do the work.

I originally bought this to drill holes. Guess what. It's not a unibit. LMAO. But you can make a square hole larger and round. You know when you cut several slivers, and break them? I use it to freshen those edges.

Really impressed by the price. A drill and a beveling bit with tons of abrasive that cuts quickly in ceramic. I didn't use the hex adapter since I have a grinder, but that piece is included too. I used the drilling bit for a bunch of holes in ceramic and I have to say it works really smooth. No signs of wearing out either. At the end I used the beveling bit to make the holes look perfect. Really good buy and handy set.

I used it to drill two holes in my granite countertop and it worked great.It cut through quickly and clean. I cooled it with water while drilling.The holes fit well with my water filter faucet. I used my angle grinder to drive the bit.I only drilled two holes, so I can't say how it will hold up in the long run, but it looks to be in very good shape. I suspect that it would last a long time.I love that it includes a beveling bit as well. It came handy for the final finish. Again, no signs of wear. I highly recommended this set for handy work at home.

These do the job. Used mine for shaping edge of granite. Worked great.

By far best bit and amazing price for both. Used Calida in the past but these are my new go to. Amazing clean bits and way cheaper
