BMT40/BMT45/BMT55 ER16 Speed-Increasing Power Tool Holder
Precision-machined from high-grade alloy steel for exceptional durability and reduced vibration during high-speed operations. Hardened and ground surfaces ensure ultra-tight tolerances (±0.003mm) for superior tool stability. Optimized for CNC milling, engraving, and high-efficiency drilling in aerospace, automotive, and precision mold manufacturing. Features a balanced design (G2.5 grade) to minimize runout at 20,000+ RPM. Direct ER16 collet compatibility supports shank sizes 1-10mm, enabling quick tool changes without adapters. Anti-corrosion nickel plating extends lifespan in harsh workshop environments. Exclusive stepped-shank design enhances grip in BT30/BT40 spindle interfaces, preventing slippage under heavy loads. Ideal for aluminum, composites, and hardened steel machining. Global wholesale pricing with MOQ flexibility—stock up for factory production lines or resale distribution. Ships with ISO9001 certification and 12-month warranty.
