05Z029 - Walter Centering Pin for 1-Inch Depth Annular Cutters

Precision Centering for Annular Cutters

The Walter 05Z029 Pilot Pin is a critical accessory designed for use with high-performance annular cutters. Engineered to fit cutters with a 1-inch depth of cut, this pilot pin serves as the central guide for your magnetic drilling operations. Before the cut begins, the pin allows the operator to precisely position the cutter over the center punch mark, ensuring hole accuracy down to the millimeter.

Constructed from high-quality hardened steel, this pin is built to withstand the rigorous forces of heavy-duty drilling. Unlike inferior pins that may bend or wear prematurely, the Walter 05Z029 maintains its straightness and rigidity, which is vital for the safety and longevity of your expensive annular cutters. A bent pin can lead to cutter breakage or misalignment, making this durable component a smart investment for any fabrication shop.

Dual-Action Functionality

Beyond simple positioning, this pilot pin acts as the flow control valve for internal coolant systems. As the pilot pin retracts into the arbor during the drilling process, it allows coolant to flow directly to the cutting teeth, maximizing tool life. Upon completion of the hole, the spring-loaded mechanism behind the pin forcefully ejects the metal slug, clearing the cutter for the next operation immediately. This seamless integration of centering, cooling, and ejecting makes it an indispensable part of the Walter annular cutter system.

Compatibility

This specific pilot pin is optimized for use with Walter's extensive line of core cutters, including the SST Core Cut, ICECUT, and CARBIDE series. It is sized specifically for 1-inch depth cutters. Using the correct length pilot pin is crucial; a pin that is too short will not center the tool, while one that is too long may prevent the cutter from reaching full depth.
