Looks like the abrasives are not worn

Cut 3 holes in a concrete countertop with no issues. Looks like the abrasives are not worn, so should last.
1-1/4" Granite Success and Ease

I bought this product for faucet and 1-3/4" for drain hole. Drilled through 1-1/4" granite with water hose on constantly and it was smooth sailing. Don't buy drill adapter, make one.
This worked very well to go through 1. 5" ...
Bissell J. Smith•July 28, 2016
This worked very well to go through 1.5" of granite counter top to put in a faucet for a filter/osmosis system. I used a large Milwaukee industrial 1/2 inch drill (w/o the hammer function) and it went through in about 10min w/o much wear at all. I occasionally stopped and cooled down the head w/a dip into water. It served it's purpose. The only hard part was getting it started w/o sliding around. I found getting up on the counter - using the 2nd stabilizing adjustable handle - and positioning myself over the drill hole stopped the sliding a lot.
