Our 8-inch CBN sharpening wheel delivers exceptional durability and extended service life for professional tool sharpening applications. Engineered with premium cubic boron nitride abrasive electroplated onto a precision steel core, this grinding disc maintains consistent grit exposure throughout its lifetime, ensuring reliable sharpening performance from first use to last.

• Extended Service Life: CBN abrasive retains sharpness 5-8x longer than conventional aluminum oxide wheels, significantly reducing replacement frequency and downtime.
• Wear Resistant Electroplated Coating: Single-layer nickel electroplated bond secures CBN grains firmly, preventing premature grit pull-out and ensuring uniform wear over time.
• Consistent Grit Retention: 180 grit particle distribution provides smooth, precise sharpening with minimal material removal, preserving tool geometry and extending tool life.
• Heat Dissipation: Steel core construction efficiently dissipates heat during grinding, preventing tool edge temper loss and blueing.
• No Dressing Required: Unlike traditional vitrified wheels, electroplated CBN requires no periodic dressing, maintaining its profile and diameter throughout service life.

Ideal for sharpening high-speed steel (HSS) woodturning tools including gouges, skews, parting tools, and scrapers. Compatible with 5-inch, 6-inch, 8-inch bench grinders with 1-1/4 inch arbor adapters. Suitable for both professional woodturners and industrial tool sharpening operations where durability and long service life are critical requirements.
