1" (25mm) Demi-Bullnose Sintered Diamond Router Bit - 50/60 Grit B-Profile Stone Wheel
Professional Sintered Metal Bond Demi-Bullnose bit for stone edge profiling. This 50/60 Grit tool is ideal for refining the profile on 25mm (1") or 20mm (3/4") stone slabs. Because it is a sintered bond, the diamonds are embedded throughout the metal for extreme longevity and consistent performance.

Speed: Best results at 3,000 – 4,500 RPM. Wet use is recommended to maximize the life of the sintered matrix.
This 50/60 grit bit is an excellent 'Position 2' tool. It removes the heavy grind marks left by coarser 40-grit bits, significantly cutting down on your hand-polishing time. The sintered construction ensures the profile remains true over hundreds of linear feet.
