Winona Van Norman Round CBN Inserts - 3/8" Double-Sided Cubic Boron Nitride for Vertical Milling & Boring

Unleash the full potential of your machining with Winona Van Norman's CBN Inserts. Engineered with Cubic Boron Nitride—the second hardest material on earth—these inserts are designed to excel where traditional tools fail. Our double-sided, 3/8" round CBN inserts provide unmatched durability and precision for vertical milling and boring applications, particularly on hardened materials. The unique geometry and exceptional edge strength ensure a smooth, chatter-free cutting action, allowing for incredibly high feed rates and a superior surface finish. Ideal for aggressive roughing, precise profiling, and critical tasks like engine head and block resurfacing, our CBN inserts offer a cost-effective solution for maximizing productivity and achieving the cleanest, most accurate finish on the market. CBN Insert, 3/8" Round, 1/8" Thick, Double Sided, Edge Honed Sharp Uncoated (CBN - Cubic Boron Nitride - SUPERABRASIVE). For engine block and head surfacing, Vertical Milling and Boring.

• Use for block and head resurfacing; vertical milling and boring.
• Ultimate Hardness: Made from Cubic Boron Nitride (CBN), second only to diamond, for superior performance on hardened steel and other tough materials.
• Double-Sided Design: Each 3/8" round insert provides multiple cutting edges, extending tool life and reducing the frequency of changes. 3/8" Round, 1/8" Thick
• Exceptional Edge Strength: The robust round shape resists chipping and breaking, even during heavy, interrupted cuts.
• High-Speed Machining: Designed for high feed rates and deep cuts, significantly boosting material removal rates and overall productivity.
