Enhance the accuracy and capability of your machining setups with our Precision ER Collet Chuck Tool Holder Handle. Also known as a straight shank extension rod, this industrial-grade hardware is engineered to hold ER-series spring collets securely. It acts as a robust extension interface between your main spindle motor and your cutting bits. Made from ultra-hardened carbon steel, it absorbs heavy radial vibrations, making it an essential component for custom desktop CNC builds, PCB milling machines, and automated robotic end-effectors.
Industrial-Grade Hardness: Forged from premium 20 CrMnTior carbon steel, heat-treated to resist bending, deformation, and surface wear under high torsional stress.
Ultra-Low Runout Accuracy: Precision ground surfaces guarantee a concentricity tolerance of le 0.008 mm, dramatically reducing bit chatter and extending cutting tool lifespan.
Deep Hole Extension: The straight shank design allows the tool holder to reach deep into restricted profiles, tight pockets, or custom structural molds.
Integrated Clamping Nut: Features a balanced, precision-threaded hex or mini type (M-type) nut that clamps down uniformly onto spring collets for a slip-free grip.
