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

CBN Pins (Cubic Boron Nitride) Grinding Pin for Tool Steels

CBN Pins (Cubic Boron Nitride) are engineered for precision access in tight, hard-to-reach areas. With diameters from 0.02" to 0.25", these pins excel in applications where heat distortion must be minimized—CBN runs significantly cooler than diamond. Ideal for grinding and polishing hardened tool steels, superalloys, and other high-performance materials, CBN Pins offer superior wear resistance, edge retention, and surface finish quality. Perfect for mold and die makers seeking accuracy and efficiency in demanding materials.

 

Features:

  • Available in diameters from 0.02" to 0.25"
