Tapered White Stone for sanding and smoothing wood.
White stones are made from aluminum oxide and work very well when you need to finish or polish a surface.
This tapered aluminum oxide bur is nice for reaching into tight places where you need to smooth or polish. However, aluminum oxide burs can be shaped easily using a diamond stone.
Shank size is 1/16″ and maximum recommended speed is 150,000 rpm – you will want to regulate your high speed engraver down when using these.
