Techniks 22971 End Mill Holder CAT40 Taper Shank

Product Description

The TECHNIKS 22971 is a CAT40 taper shank end mill holder designed for use in CNC machining centers. It accepts end mills through a 16 mm bore and features a 48 mm nose diameter, providing a secure, rigid connection between the spindle and cutting tool. With a 2.5-inch projection and 5.187-inch overall length, this holder positions the end mill for standard reach applications in milling operations. Installation and removal are handled by qualified CNC machine operators or toolroom technicians as part of routine tool-change procedures.

This end mill holder is suited for vertical and horizontal machining centers equipped with a CAT40 spindle interface. The CAT40 taper is a widely used standard in North American production and job-shop environments for milling ferrous and non-ferrous materials. At 2.5 inches of projection, it covers typical short-to-medium reach setups without requiring extended-reach tooling. The holder does not include through-coolant capability, making it appropriate for applications where flood or mist coolant delivery from the machine exterior is sufficient.

Key Features

• CAT40 taper shank for compatibility with CAT40-spindle machining centers
• 16 mm bore diameter for secure end mill retention
• 48 mm nose diameter for rigid tool grip and reduced runout
• 2.5-inch projection suits standard-reach milling applications
• 5.187-inch overall length for predictable tool-length offsets
• No through-coolant - optimized for external coolant delivery setups

Compatibility

Designed as an OEM-style replacement or direct tooling addition for CNC machining centers with a CAT40 spindle taper interface.

Installation Notes

Installation should be performed by a qualified CNC operator or toolroom technician. Power down the machining center spindle and engage the machine lock before removing or installing tool holders. Use the machine manufacturer's recommended pull stud and drawbar torque procedure. Inspect the taper shank and spindle bore for chips or contamination before seating the holder.
