Secure straight-shank end mills with absolute reliability under heavy cutting loads using Side Lock Arbors (Weldon) PSC Tool Holders. Specially engineered for modern multi-tasking machines, turning-milling centers, and high-performance CNC milling stations utilizing ISO 26623 polygon taper spindle connections (PSC), these tool holders use a heavy-duty side clamping screw to lock firmly against the Weldon flat of the cutter shank. The unique polygon taper design provides automatic self-centering, simultaneous face contact, and exceptional torque transmission, completely eliminating tool pull-out and rotational slippage during aggressive slotting and roughing operations.
