Techniks 22963 End Mill Holder CAT40 2.5 Inch Projection

Product Description

The TECHNIKS 22963 is a CAT40 taper shank end mill holder designed for securing end mills in CNC machining centers. It provides a 2.5-inch projection from the spindle face, making it well-suited for operations that require reach clearance without sacrificing rigidity. The holder features a 6 mm bore diameter and a 25 mm nose diameter, with an overall length of 5.187 inches. Installation and tool changes are handled by machinists and CNC setup technicians working with CAT40-compatible spindles. This holder does not include through-coolant capability.

This end mill holder is intended for use in vertical and horizontal machining centers equipped with CAT40 spindle interfaces. The 2.5-inch projection suits applications where the tool must reach into pockets or past workholding fixtures. It is a standard choice in job shops, production facilities, and toolrooms running CAT40 tooling systems. The holder is appropriate for a wide range of end milling operations including slotting, profiling, and face milling where a solid, non-coolant-through holder meets the application requirements.

Key Features

• CAT40 taper shank for compatibility with CAT40 spindle interfaces
• 2.5-inch projection for extended reach applications
• 6 mm bore diameter to accept standard metric-shank end mills
• 25 mm nose diameter for stable clamping geometry
• Overall length of 5.187 inches for consistent gage-length setup
• No through-coolant - suitable for flood or mist coolant delivery setups

Compatibility

Designed as an OEM-style end mill holder for machining centers with CAT40 taper spindle interfaces.

Installation Notes

Installation requires a CAT40 pull stud (retention knob) matched to the spindle drawbar specification of the target machine - verify pull stud type before assembly. Use a proper toolholder tightening fixture and end mill holder wrench to torque the clamping screw; do not clamp end mills in a vise or by hand alone. Ensure the spindle is fully stopped and the machine is in an appropriate safe state before loading or unloading the holder. Follow the machine tool builder guidelines for gage length and tool offset entry after installation.
