BB Ball Nose End Mill – Non-Standard Radius R0.55–R5.95 | Two Decimal Point | Aluminum & Steel | CNC Milling

BB Ball Nose End Mill – Non-Standard Two Decimal Point Radius (R0.55–R5.95)

Precision-ground solid carbide ball nose end mills with non-standard two decimal point radii (e.g., R0.55, R1.05, R2.95). Designed for applications requiring exact intermediate radii not available in standard tooling. Available in 150mm and 200mm overall lengths for extended reach machining.

Key Features

• Full Polished Helix Design – Fully ground helical flutes reduce burrs, prevent tool binding, and improve cutting efficiency
• Blade Passivation – High-end passivation grinding delivers a sharp, burr-free cutting edge
• TiSiN Nano-Coating – Multi-layer coating enables roughing to finishing on materials up to HRC55; extends tool life and reduces tool changes
• Micro-Grain Solid Carbide – One-piece carbide construction for anti-vibration durability and break resistance
• Chamfered Round Shank – Universal design for secure, slip-free clamping with strong compatibility

Specification Guide
