Techniks 22977 CAT40 End Mill Holder 4 Inch Projection

Product Description

The TECHNIKS 22977 is a CAT40 taper shank end mill holder designed for use in CNC machining centers that accept the CAT40 spindle interface. It provides a 4-inch projection, an overall length of 6.687 inches, and a 32 mm bore diameter to accommodate standard end mill shanks. The holder features a 72 mm nose diameter and a 72 mm flange diameter, conforming to the standard CAT40 geometry used in vertical and horizontal machining centers. Machinists and CNC setup technicians install this holder when standard or extended-reach milling operations require a secure, repeatable taper connection between the spindle and cutting tool.

This holder is suited for milling applications in job shops, production machine shops, and tool rooms running CAT40-equipped machining centers. The 4-inch projection makes it appropriate for reaching into deeper workpiece features or clearing fixture interference where shorter holders cannot reach. It is installed and removed by qualified CNC machinists or toolroom technicians as part of standard tooling setup and changeover procedures.

Key Features

• CAT40 taper shank interface for compatibility with standard CAT40 spindles
• 4-inch projection for extended reach during milling operations
• 32 mm bore diameter accommodates common end mill shank sizes
• 72 mm flange and nose diameter conforms to standard CAT40 dimensions
• Overall length of 6.687 inches for predictable tool length offset setup

Compatibility

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

Installation Notes

Installation requires a CAT40-compatible tool setter or pull stud and should be performed with the machining center spindle powered down and the machine in a safe, locked-out state per applicable lockout/tagout procedures. Use a torque wrench to tighten the retention knob to the spindle manufacturer's specified torque. Verify tool length offset in the machine controller before beginning a cutting operation. Handle the taper shank carefully to avoid nicks or contamination that could affect runout.
