Achieve high concentric repeatability and ultra-secure bar workholding during high-speed CNC turning operations using industrial-grade Push-out Collets. Designed primarily for automatic lathes and bar feeding systems, these specialized clamping sleeves are pushed forward against a closing sleeve taper to lock raw stock or workpieces firmly into position. The structural push-out mechanical action ensures positive axial bar positioning against sub-spindle stops, minimizing material deflection and maintaining rigid rotational tracking accuracy under severe heavy-duty cutting forces.
