The Regis Manufacturing CBN38 is a high-performance double-sided cubic boron nitride (CBN) replacement cutter designed for precision milling operations on engine blocks, cylinder heads, and other hard ferrous materials. This professional-grade cutting tool measures 1/8 inch thick with a 3/8 inch round profile, delivering exceptional durability and cutting performance in demanding machining applications.

Key Features:

• Double-sided CBN construction for extended tool life and reversible cutting edges
• 1/8" thickness with 3/8" round profile optimized for milling head applications
• Cubic boron nitride material second only to diamond in hardness
• Excellent thermal stability maintains cutting edge at extreme temperatures
• Superior wear resistance for aluminum alloy, cast iron, and diesel engine heads
• Delivers clean, precise cuts on all shop work with minimal tool wear

CBN cutters like the CBN38 are specifically recommended for use on aluminum alloys, cast iron, and diesel heads where exceptional hardness and heat resistance are required. The double-sided design allows you to flip the cutter when one side wears, effectively doubling the usable life compared to single-sided alternatives.
