Precision BBT40-LBK4-85 Boring Head Shank for CNC Machining

High-grade alloy steel construction ensures maximum durability and wear resistance under heavy machining loads. Hardened and ground surfaces achieve tight tolerances (±0.005mm) for superior concentricity in precision boring operations.

Heat-treated taper interface (BT/BBT40) guarantees vibration-free performance during high-speed milling and deep hole boring. Compatible with major CNC machine brands including Haas, Mazak, and DMG Mori.

Optimized coolant channels prevent chip buildup during prolonged machining of cast iron, steel alloys, and titanium workpieces. Ideal for mold making, aerospace components, and automotive jig production requiring micron-level accuracy.

Direct replacement part with ISO 7388-2 compliance, featuring laser-etched identification for quick tool recognition in industrial environments. Includes anti-corrosion coating for extended service life in humid workshop conditions.

Exclusive bulk pricing available for machine shops and OEM manufacturers with same-day global shipping from our bonded warehouses. Custom packaging solutions available for wholesale orders exceeding 50 units.
