Description of Bullnose Diamond Profiler Concrete Countertop
3/8" (10mm) radius demi-bullnose shape. Vacuum Brazed Diamond Grit: 35/45, coarse. Use on polisher or grinder with 5/8"-11 Thread. Both Wet or Dry in use , recommend speed 3500- 4000 RPM. Works great for grinding granite,marble ,etc stones. and concrete tiles countertops edges.
When I tried this product it didn't live up to my expectations.The diamond grit seemed to wear out after just a few uses, leaving rough edges on my countertop. On the plus side, the shape of the bit was well-designed for creating bullnose edges. However, I ultimately had to switch to a different brand for a smoother finish..
Pros
Efficiently and accurately shapes and polishes concrete countertops for a smooth finish
Quickly cuts marble into smooth, rounded edges on a manual angle grinder at approx. 2000 rpm. Leaves shallow grooves because it has such an aggressive, fast grain. Grooves are quickly removed with a 4" 50 grit Velcro disc followed by progressively finer discs to achieve the desired polish. I am satisfied.
