Available in ¼" & ⅛" diameters.
Enjoy the smooth grinding experience that these premium quality bits provide. These spindle bits allow you grind tighter inside curves than the ¾" or 1" main bits. The solid brass substrate absorbs shock while grinding, keeping vibration and noise as minimal as possible while providing the fast material removal of a standard grit with minimal chipping. Glastar's patented electroplating prevents the diamond grinding surface from flaking off over time, creating a long-lasting bit.
These bits will fit most brands of standard router-style glass grinders on the market, although they may require use of the spindle bit adaptor (sold separately).
