Precision BT40 Boring Head Set for Heavy-Duty Machining
High-performance 12mm boring cutters with ultra-fine carbide tips ensure extended tool life and chip-free finishes. Heat-treated alloy steel chuck body guarantees rigidity for high-speed operations up to 6,000 RPM. 9-piece set includes balanced F1-grade roughing heads, minimizing vibration for aerospace-grade accuracy (±0.005mm). Interchangeable with BT30/BT40/BT50 spindles—ideal for CNC mills, lathes, and jig boring machines. Industrial-grade black oxide coating prevents corrosion in coolant-heavy environments. Perfect for automotive cylinder boring, mold base machining, and large-batch industrial part production. Dual-set screw design eliminates tool slippage during deep-hole boring. Includes precision-ground tungsten carbide inserts (TPG221) for cast iron/stainless steel. Global wholesale pricing—bulk orders ship with custom HS-code documentation for seamless clearance.
