05Z030 - Walter Pilot Pin for 2-Inch Depth Annular Cutters (7/16" Dia)

Precision Centering and Ejection for Annular Cutters

The Walter 05Z030 Pilot Pin is a critical accessory designed to optimize the performance of high-performance annular cutters. Engineered specifically for use with cutters featuring a 7/16-inch diameter and a 2-inch depth of cut, this pin serves as the central guide for your magnetic drilling operations. Manufactured from high-grade steel, the pin is expertly hardened and precision-ground to withstand the rigorous forces of heavy-duty metal fabrication. Its robust construction ensures it maintains straightness and rigidity, which is essential for accurate hole positioning.

Beyond simple positioning, the 05Z030 plays a vital role in the thermal management of the cutting process. In magnetic drilling units equipped with internal lubrication systems, this pilot pin acts as a flow control valve. It retracts as the cut begins, allowing coolant to flow directly to the cutting teeth where it is needed most, and seals the flow when the cutter is lifted. Furthermore, the pin is spring-loaded by the machine's arbor to automatically eject the solid metal slug immediately after the hole is completed, preventing jams and reducing downtime between cuts. It is fully compatible with Walter's premium line of tooling, including SST Core Cut, ICECUT, and CARBIDE series cutters.
