High Precision BT30/BT40/BT50 Pull-back Tool Holder – DC Series (DC04/06/08/12)

Ultra-Precision Machining
– CNC-milled from high-grade alloy steel with strict tolerance (±0.005mm) for flawless spindle alignment, minimizing vibration in high-speed operations (up to 20,000 RPM).
Dual-Purpose Grip
– Patented pull-back mechanism ensures instant tool release + secure clamping, ideal for heavy milling (steel/titanium) and delicate engraving (aluminum/composites).
Anti-Corrosion Defense
– Hardened chromium plating protects against coolant/abrasive wear, extending lifespan by 3X vs. standard holders.
Universal Spindle Fit
– Seamlessly compatible with BT30/BT40/BT50 interfaces (ISO 7388-1 standard), perfect for CNC mills, lathes, and multi-axis machining centers.
Industry-Proven Durability
– 50% thicker taper walls vs. generic models prevent deflection during deep-cavity cutting (tested at 800+ hour continuous run).
Global Bulk Ready
– Direct-from-factory pricing (MOQ 50+ units), shipped with ISO-certified inspection reports for industrial buyers.
