Widia (carbide) CNC Router Bits for Stone, Marble, and Granite
High-quality, made in Italy, 10mm straight shank writing mills for stone lettering and relief finishing.
Ideal for engraving and lettering on marble, stone, and granite.
You can choose from the 2 different mill versions: marble (M version) and granite (G version) that differs for their widia bond. You can also choose bits with a central water feed (for the inner water flow) or the not-holed model.
To use 10 mm shank tools on your CNC stone router you need an ER-Collet for 1omm diameter tool fitting.
