Techniks 22711-8 Face Mill Holder CAT40 0.75 in Pilot 8 in Arbor

Product Description

The TECHNIKS 22711-8 is a CAT40 face mill holder designed for securing face mills and shell mills in CNC machining centers. It features a 0.75 inch pilot diameter and an 8 inch arbor length, making it suitable for extended-reach face milling operations. The CAT40 taper provides a rigid, repeatable connection to the machine spindle, supporting accurate cuts at production feed rates. Machinists and tooling technicians install this holder in horizontal and vertical CNC machining centers where a stable, high-torque connection between the spindle and cutting tool is required.

This face mill holder is used in production and job-shop CNC machining environments. The 8 inch arbor length accommodates setups that require clearance over fixtures, tall workpieces, or stepped part geometries. The 0.75 inch pilot diameter mates with compatible face mill bores for positive tool location and concentricity. It is well suited for steel, cast iron, aluminum, and other common workpiece materials where face milling operations are performed on CAT40-equipped machining centers.

Key Features

• CAT40 taper shank provides rigid, repeatable spindle connection on standard CNC machining centers
• 0.75 inch pilot diameter for positive tool location and concentricity
• 8 inch arbor length supports extended-reach and fixture-clearance setups
• Designed for face mills and shell mills requiring a pilot-style holder interface

Compatibility

Designed as a direct-fit face mill holder for CAT40-taper CNC machining centers accepting a 0.75 inch pilot diameter face mill or shell mill bore.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Power down and lock out the machining center spindle before mounting or removing the holder. Use the appropriate CAT40 retention knob and tighten to the machining center manufacturer's drawbar torque specification. Inspect the taper shank and spindle bore for nicks, chips, or contamination before seating the holder to ensure full contact and runout accuracy.
