This profile 'B' router bit is a very aggressive profile tool for doing demi bullnoses on 30mm granite and other natural stones. These are equipped with 2 bolts, 8mm and 10mm to fit Master, Sector and other profiling machines. Since they are continuous impregnated diamond tooling they give consistent details with less chipping and smoother finishes.
This is a position 3 router bit designed to give you the final prepolished shape on the edge of the stone. You can use this bit after using positions 1 & 2, allowing you to start polishing the stone with a much finer diamond polishing pad (like a 400 grit or 800 grit diamond pad), which will shorten your completion time as you will have to spend much less time polishing the edge to match the factory finish.These are a very high quality bit designed to give you an aggressive removal rate and a long life while providing you with a consistent edge detail.
