48H460 - Walter No. 4 Drill Drift Key for MT4 and MT5 Tapers

Professional Grade Tooling Removal

The Walter 48H460 Drill Drift Key No. 4 is an essential industrial accessory designed for the safe and efficient removal of taper shank tools. In heavy-duty machining and fabrication environments, the integrity of your machine spindles and tool sockets is paramount. Using makeshift tools or inferior drifts can lead to damaged tapers, increased runout, and costly equipment repairs. Walter Surface Technologies has engineered this drift key to meet the rigorous demands of professional machine shops, ensuring that tool changes are performed quickly and without damage to the mating surfaces.

Hardened for Durability

Unlike generic mild steel drifts that tend to mushroom, bend, or chip after repeated use, the Walter 48H460 is manufactured from high-quality, fully hardened steel. This heat treatment process imparts exceptional strength and impact resistance, allowing the drift to transmit the force of a hammer blow directly into the wedging action required to break the friction fit of a Morse Taper. The hardness ensures the key maintains its precise shape over years of service, providing a reliable solution for ejecting drill bits, reamers, and drill chuck arbors.

Compatibility and Application

This specific drift is sized as a No. 4, making it suitable for use with Morse Taper #4 (MT4) and #5 (MT5) tooling. It is the correct geometry to fit standard drift slots found on drill press quills, lathe tailstocks, and reduction sleeves. By inserting the drift into the slot and applying a sharp tap, the tapered wedge forces the tool out safely. Whether you are operating a radial arm drill, a magnetic drilling unit, or a large milling machine, having the correct size drift key on hand is critical for workflow efficiency and operator safety.

The Walter Advantage

Walter is synonymous with superior surface technologies and tooling solutions. By choosing a Walter drift key, you are investing in a tool that respects the precision of your machinery. The 48H460 is finished to resist corrosion and designed with operator safety in mind, featuring smooth edges to prevent handling injuries. It is a small but vital component in any complete tool crib or machinist's toolbox.
