Collection: CBN Pins - "BL" Series - Taper Shank

CBN Pins (Cubic Boron Nitride) are the ideal solution for accessing tight, intricate spaces in hardened materials where heat sensitivity is critical. Available in diameters as small as 0.02", these precision-engineered tools run cooler than diamond, helping prevent heat distortion while extending tool life. Perfect for mold and die professionals working with hardened steels and superalloys, CBN Pins offer exceptional durability, longer cutting edge retention, and improved surface finish—all while reducing overall polishing and grinding costs.

Features:

• Available in ultra-small diameters from 0.02" to 0.25"
• Made from CBN, which runs cooler than diamond to reduce heat distortion
• Ideal for hardened materials: high-speed steels (M2, M3, M7, T15), die steels (D2, D3, A, O), stainless, titanium, and nickel/cobalt superalloys
• Delivers longer tool life and more parts per hour
• Improves edge retention and reduces breakdown
• All CBN "BL" Series Pins are 2-1/2" overall length on 1/8" shanks.
