High-Precision CNC Tool Holder – BT40/BT30 with ER32/ER25 Chuck

Ultra-Precision Machining
– Crafted from premium alloy steel with advanced heat treatment, ensuring superior rigidity and wear resistance for micron-level accuracy in high-speed CNC operations.
Dynamic Balance Optimized
– Engineered for vibration-free performance at 15,000+ RPM, minimizing tool deflection and extending cutter life for aerospace, automotive, and mold-making applications.
Dual-Collet Versatility
– Compatible with both ER32 and ER25 collets (sold separately), offering flexibility for drills, end mills, and reamers across multi-axis machining centers.
Interchangeable BT30/BT40 Taper
– Seamlessly fits BT30 and BT40 spindle interfaces with ISO 7388-1 compliance, ideal for quick tool changes in mass production environments.
Mirror-Finished Surfaces
– Hardened and ground contact surfaces with anti-corrosion coating maximize taper grip force and prevent fretting corrosion in coolant-heavy workflows.
Strict QC Standards
– Each unit undergoes dynamic balancing (G2.5 grade) and runout testing (<0.005mm) to meet ISO 1940-1 norms for high-torque heavy cutting.
Bulk Order Advantage
– Direct factory pricing with MOQ discounts, shipped globally with OEM-grade quality assurance. Stocked for immediate dispatch.
Target Industries
– Precision parts manufacturing, titanium machining, die-casting mold finishing, and medical device production.
