Techniks 22959-3/8 Set Screw End Mill Holder 1/2 in

Product Description

The TECHNIKS 22959-3/8 is a set screw designed for use with end mill holders in CNC machining and milling applications. This accessory secures the end mill within the holder bore, maintaining tool position under cutting loads. The set screw features a 1/2 inch hole diameter and is a direct-fit component for compatible end mill holder bodies. Weighing 0.1 pounds, it is a compact, single-piece hardware item. Machinists, CNC operators, and tool crib technicians typically stock these as replacements or spares to keep tooling assemblies running without downtime.

This set screw is used in machine shop environments, tool and die operations, and CNC machining centers where end mill holders require secure tool retention. It is suited for both roughing and finishing setups where tool pullout prevention is critical. The 1/2 inch hole diameter targets standard end mill holder configurations. It is sold individually and is appropriate for shops maintaining an inventory of replacement tooling hardware.

Key Features

• Set screw design provides positive tool retention in end mill holder bores
• 1/2 inch hole diameter fits standard end mill holder configurations
• Lightweight at 0.1 pounds, minimal impact on tooling assembly weight
• Single-piece component, sold individually (MOQ 1, Pkg Qty 1)
• Direct replacement hardware for maintaining CNC tooling assemblies

Compatibility

Designed as a replacement set screw accessory for end mill holders requiring a 1/2 inch hole diameter set screw. Consult your end mill holder documentation to confirm thread size and seating requirements before ordering.

Installation Notes

Installation is performed by qualified machinists or CNC tooling technicians. Ensure the machine spindle is fully stopped and the tool holder is removed from the spindle before servicing set screws. Use the correct hex key or Allen driver for the set screw drive size to avoid rounding. Do not overtighten, as this can damage the holder bore or distort the tool shank seating surface.
