Techniks 22709 Face Mill Holder CAT40 1/2 in Pilot

Product Description

The TECHNIKS 22709 is a CAT40 face mill holder designed for secure, rigid mounting of face mills and shell mills on CNC machining centers. With a 0.5 inch pilot diameter and a 1.37 inch arbor length, this holder provides a stable interface between the machine spindle and the cutting tool. The CAT40 taper is one of the most widely used spindle interfaces in North American CNC machining, and this holder is built to those dimensional standards. Machinists and tool crib technicians working in job shops, production shops, and maintenance environments rely on this type of holder for face milling operations on ferrous and non-ferrous workpieces.

This face mill holder is suited for horizontal and vertical machining centers equipped with CAT40 spindles. It accepts face mills and shell mills with a matching 0.5 inch pilot bore. The 1.37 inch arbor length provides clearance and engagement depth appropriate for standard shell mill bodies. Typical applications include face milling, shoulder milling, and surfacing operations in general manufacturing environments.

Key Features

• CAT40 taper shank for compatibility with standard North American CNC machining center spindles
• 0.5 inch pilot diameter for precise mill-to-holder centering
• 1.37 inch arbor length provides adequate engagement for shell mill bodies
• Rigid holder design minimizes runout and supports consistent surface finish
• Weighs 2.5 pounds for a solid, balanced feel on the spindle

Compatibility

Designed for use with CAT40 spindle machining centers and face mills or shell mills with a 0.5 inch pilot bore.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. Power down and lock out the machining center before mounting or removing toolholders. Use the appropriate pull stud and torque the retention knob to the machine manufacturer's specification - do not estimate. Inspect the taper shank and spindle bore for chips, burrs, or contamination before seating the holder.
