Silicon carbide and aluminium oxide grinding wheels for multi-reason strength tools.
• Dimensions: 20 x 3 x 1.5mm
• green (silicon carbide): for grinding non ferrous substances together with solid iron, tungsten carbide, non-magnetic stainless steel, aluminium and ceramics
• purple (aluminium oxide): for high alloyed tool steels whilst a cooler grinding motion is needed
• White (aluminium oxide): for widespread tool sharpening and hardened or HSS substances
• Silicon carbide is harder than aluminium oxide
