Grinding disc honer Tetrabor®
Design: made from pure, sintered boron carbide. Extreme hardness (approx. 35000 N/mm²) and resistance of boron carbide enables efficient honing for grinding discs up to Ø 300 mm. Does not tear the grit out of the binding rather cuts it smoothly through.
Note: Only use the edge to hone, not with the flat surface.
