Techniks 22907-4 End Mill Holder CAT40 1/8 Inch Bore

Product Description

The TECHNIKS 22907-4 is a CAT40 taper shank end mill holder designed for secure tool retention in CNC machining centers. It accepts a 1/8 inch bore and provides 4 inches of projection from the spindle face, giving operators the clearance needed for a wide range of milling operations. The nose diameter measures 11/16 inches, and the overall length is 6.687 inches. Machinists and CNC technicians install this holder when setting up end mills in CAT40-compatible spindles. It does not include through-coolant capability.

This end mill holder is suited for use in vertical and horizontal CNC machining centers equipped with CAT40 spindle interfaces. It is a standard choice for production shops and toolrooms running smaller-diameter end mills. The 4 inch projection is useful in applications requiring extended reach while maintaining concentricity and rigidity at the spindle connection.

Key Features

• CAT40 taper shank for compatibility with standard CAT40 spindle tooling systems
• 1/8 inch bore diameter for small-diameter end mill retention
• 4 inch projection provides extended reach from spindle face
• 11/16 inch nose diameter for clearance in tight setups
• No through-coolant, keeping design straightforward for standard dry or flood coolant setups

Compatibility

Designed as an OEM-style replacement and standard fitment for CNC machining centers with CAT40 taper spindle interfaces accepting 1/8 inch bore end mill holders.

Installation Notes

Installation is performed by qualified CNC machinists or toolroom technicians. Power down and lock out the machining center before changing tooling. Use the appropriate pull stud and torque the retention knob per the machine manufacturer specification. Verify runout with a dial indicator after installation before running the spindle at speed.
