EXPERT PRO (CBN) PDTools sharpening stones on a base, 160x25x7 mm — | 1/0 µm
EXPERT PRO CBN sharpening stone – mounted on a base. A premium-quality finishing stone with CBN abrasive material, ideal for ultra-fine polishing and edge finishing on high-carbon and stainless steel. A 3 mm polyamide monolayer binder ensures uniform abrasive action and long-term stability. Cubic boron nitride (CBN) delivers outstanding performance on hard steels, including high-carbon and alloy grades. It polishes hard steels faster than diamond, while achieving equally perfect edges. Impact-resistant and dimensionally stable during repeated use. Mounted on a laser-engraved aluminum backing plate: 160 × 25 × 4 mm. Working surface dimensions: 150 × 25 × 3 mm. Ideal for final sharpening and mirror polishing. Use with oil, soapy water, or an abrasive suspension to prevent abrasive build-up, especially on sticky or alloyed steels.
