I needed to drill some clean 2" diameter holes in concrete pavers, and this bit did a masterful job. It left a very neat appearance at the paver surface, which met the cosmetic requirements of the job.
It helps to clean the core out of the bit in small increments; if you let the core extend all the way to the base of the bit, clearing it out can be tedious and time-consuming.
The only note of caution I'd like to make is that when a bit of this size or larger gets more than an inch or so into the hole, it's much more prone to grabbing than is a smaller-diameter bit. One time it grabbed hard and nearly twisted my arms off. I had to be careful to take small bites and keep a relaxed grip on the rotohammer.
