The pullback toolholder solves the problems of loosening and precision issues in traditional toolholders with its mechanical anti-loosening structure and ultra-precision manufacturing, making it particularly suitable for deep cavity machining and high-speed precision milling.

Backhand tool holder: Anti-interference in deep hole machining

     The pullback toolholder solves the problems of loosening and precision issues in traditional toolholders with its mechanical anti-loosening structure and ultra-precision manufacturing, making it particularly suitable for deep cavity machining and high-speed precision milling.

     The pullback toolholder secures the tool through a linkage structure of a pullback collet and a pullback screw: one end of the collet is designed with an outwardly flared bevel; when the pull rod is pulled back, the collet is drawn into the tapered hole of the toolholder, and the pressure from the bevel causes the collet to contract and clamp the tool. A rectangular protrusion on the side of the collet engages with a concave slide inside the toolholder to restrict the collet's rotation; a positioning bolt further passes through the positioning hole of the collet, providing double fixation to prevent loosening caused by machining vibrations.
