05Z001 - Walter 05Z001 Centering Pin for 1-Inch Annular Cutters

Precision Centering and Ejection for Annular Cutters

The Walter 05Z001 Pilot Pin is a critical accessory designed to maximize the performance and lifespan of your annular cutting tools. Engineered specifically for use with 1-inch depth of cut cutters, this pin is compatible with Walter's renowned SST Core Cut, ICECUT, and Carbide Core cutter series. In the realm of precision metal fabrication, the pilot pin serves three fundamental roles: positioning, coolant regulation, and slug ejection. Before the cut begins, the precision-ground tip allows the operator to align the magnetic drill exactly over the center punch mark, ensuring hole accuracy to within tight tolerances.

Constructed from high-grade steel, the 05Z001 undergoes a specialized hardening process. This treatment ensures the pin remains rigid and straight, even when subjected to the lateral forces and thermal cycles common in heavy-duty drilling applications. A bent or worn pilot pin can lead to cutter misalignment or failure to eject the slug, causing significant downtime. Walter’s commitment to quality ensures that this pin maintains its dimensional integrity over repeated use, providing a reliable guide for the cutter as it penetrates the workpiece.

Beyond positioning, the pilot pin is integral to the internal lubrication system of modern magnetic drills. As the cutter engages the material, the pin retracts into the arbor, opening a valve that allows coolant to flow down the center of the tool. This delivers lubrication directly to the cutting teeth where it is needed most, flushing away chips and reducing heat friction. Upon completion of the hole, the spring-loaded mechanism behind the pin forcibly ejects the metal slug (core) from the cutter body. This automatic ejection feature eliminates the need for manual removal, protecting the operator from hot metal and speeding up the workflow for multi-hole projects.

Whether you are working in structural steel erection, heavy equipment repair, or custom fabrication, the reliability of your consumables dictates your productivity. The Walter 05Z001 Pilot Pin is an indispensable component that ensures your 1-inch annular cutters operate at peak efficiency, delivering clean, burr-free holes every time.
