Techniks 22973 End Mill Holder CAT40 3 Inch Projection

Product Description

The TECHNIKS 22973 is a CAT40 taper shank end mill holder designed for secure tool clamping in CNC machining centers. It accepts end mills with a 20mm bore diameter and provides a 3-inch projection from the spindle face, placing the cutting tool at a consistent, repeatable gage length. The 52mm nose diameter and 5.687-inch overall length make this holder well-suited for standard milling operations where rigidity and runout control are priorities. Installation is handled by machinists and toolroom technicians working with CAT40-spindle vertical or horizontal machining centers.

This holder fits CAT40-taper spindle machining centers running end mills, slot drills, and similar straight-shank rotary cutting tools with a 20mm shank diameter. The 3-inch projection suits applications where moderate tool stick-out is needed to clear workpiece fixtures or part features without requiring an extended-reach holder. Solid construction supports high-speed and high-feed milling passes in production and job-shop environments alike.

Key Features

• CAT40 taper shank for direct spindle mounting on compatible machining centers
• 20mm bore diameter accommodates standard 20mm shank end mills
• 3-inch (3.0000 inch) projection for consistent gage length setup
• 52mm nose diameter provides a robust clamping body
• 5.687-inch overall length suits typical vertical and horizontal CNC setups
• No through-coolant passage - external coolant delivery required

Compatibility

Designed as an OEM-style end mill holder for CNC machining centers equipped with a CAT40-taper spindle interface.

Installation Notes

A licensed machinist or toolroom technician should install this holder using a proper CAT40 pull-stud and a calibrated torque wrench rated for the spindle draw-bar specification of the target machine. Always de-energize and lock out the machining center spindle before changing tooling. Inspect the taper bore and spindle taper for chips or contamination before seating the holder, and verify runout with a dial indicator after clamping to confirm acceptable concentricity before cutting.
