EXPERT PRO CBN Sharpening Stone, 4000 grit – Mounted on Blank
A high-quality finishing stone with CBN abrasive, ideal for precise edge refinement on high-carbon and stainless steels.

• 3 mm polyamide monolayer bond offers durability and even abrasive exposure

• CBN (Cubic Boron Nitride) excels in sharpening hard steels, working faster than diamond while delivering the same edge quality

• Provides fast metal removal with enhanced control and surface finish

• Highly durable, impact-resistant, and dimensionally stable during prolonged use

• Mounted on a laser-engraved aluminum blank: 160×25×4 mm

• Working surface dimensions: 150×25×3 mm

Ideal for fine sharpening and pre-polishing stages. For best results, use with oil, abrasive slurry, or soapy water to prevent abrasive clogging, especially on sticky or alloy steels.
