Techniks 43.151.64.137 CAT40 Face Mill Holder

Product Description

The TECHNIKS 43.151.64.137 is a CAT40 face mill holder designed to mount face mills and shell mills on CAT40-taper spindles in vertical and horizontal machining centers. The holder features a 0.75 inch pilot diameter and a 1.37 inch arbor length, providing a rigid, concentric interface between the spindle and the cutter. Weighing 2.45 pounds, this holder is built for production milling environments where secure cutter retention and accurate tool runout are critical. It is installed and maintained by machinists and CNC setup technicians working in job shops, tool rooms, and production machine shops.

This face mill holder is suited for use in CNC machining centers equipped with CAT40 spindle tapers. Typical applications include face milling, shoulder milling, and general surface milling operations on ferrous and non-ferrous workpieces. The 0.75 inch pilot diameter accommodates standard shell mill arbor bores, and the 1.37 inch arbor length suits compact cutter bodies where overhang must be minimized. It is a standard tooling component in setups requiring reliable cutter registration and repeatable tool changes.

Key Features

• CAT40 taper shank for compatibility with CAT40 spindle tooling systems
• 0.75 inch pilot diameter for standard shell mill and face mill arbor bores
• 1.37 inch arbor length for compact, low-overhang cutter mounting
• 2.45 pound construction suitable for production machining environments
• Rigid holder design promotes accurate cutter runout and stable cutting performance

Compatibility

Designed as an OEM-style tooling component for machining centers equipped with CAT40 taper spindles and face mills or shell mills with a 0.75 inch pilot bore.

Installation Notes

Installation should be performed by a qualified machinist or CNC tooling technician. The spindle must be fully stopped and the machine placed in a safe, locked-out state before installing or removing any toolholder. Use the appropriate spanner wrench and pull stud torque specifications recommended by the machine tool manufacturer when securing the holder in the spindle. Inspect the taper shank and spindle bore for burrs, chips, or contamination before each installation to ensure proper seating and runout.
