1-1/4 Inch Diamond Hole-Saw Bits with Pilot Drill Bit - 2pc 1-1/4" Diamond Tipped Tile Hole Saws with Guiding Bit Accurate Drilling for Porcelain Tile Ceramic Pottery Granite Stone Glass Bottles 32mm

Went through brick, granite, and quartz quite nicely. Pilot bit tends to slip with pressure, but not a show stopper. Great value.

The diamond bit drilled 6 1 1/4inch holes thru Hard Italian Tile with little effort and I’m sure it can do many more. I gave the second bit to my brother in law. One bit will last me for ages.

Does a great job cutting tile.

As advertised

I installed a mini-split in our basement. I had to drill through bricks and blocks that were poured solid. These bits cut through all of that like a hot knife through butter. There was no place locally that I could find this type of bit. Very happy with the price on these, too.
