EXPERT PRO CBN Sharpening Stone, 80 grit – Mounted on Blank
An ultra-coarse CBN stone developed for rapid reshaping and heavy sharpening of extremely hard steels, including stainless and high-carbon alloys.

• 3 mm polyamide monolayer bond ensures durability and uniform abrasive exposure

• CBN (Cubic Boron Nitride) offers faster sharpening than diamond with equally refined edge quality

• High abrasive concentration provides aggressive metal removal with reliable control

• Impact- and crack-resistant, maintaining shape and performance through extended use

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

• Working surface dimensions: 150×25×3 mm

Ideal for intensive edge restoration, setting new bevels, and removing chips. Use with oil, soapy water, or abrasive slurry to prevent clogging, especially on alloy or gummy steels.
