05Z018 - Walter 3-Inch Pilot Pin for Annular Cutters

Precision Centering and Ejection for Industrial Drilling

The Walter 05Z018 3" Pilot Pin is a critical component designed to maximize the performance and lifespan of your annular cutters. Engineered by Walter Surface Technologies, this pilot pin is manufactured from high-quality, hardened steel that is precision-ground to exacting tolerances. In the demanding environment of industrial metalworking, the pilot pin serves three fundamental roles that ensure the efficiency of magnetic drilling operations.

First, it acts as the primary positioning guide. Before the drill motor is engaged, the tip of the pilot pin allows the operator to align the cutter perfectly with the center punch mark on the workpiece. This ensures that every hole is drilled exactly where specified, reducing rework and material waste. Second, for systems utilizing internal lubrication, the pilot pin functions as a flow control valve. It retracts as the cutter enters the material, allowing coolant to flow directly to the cutting teeth, and shuts off the flow when the cut is complete, conserving lubricant and maintaining a clean workspace.

Finally, and perhaps most importantly for process speed, the 05Z018 pin is responsible for slug ejection. Upon completion of the cut, the spring-loaded mechanism behind the pin forces the solid metal slug out of the cutter body. Without a reliable, straight, and durable pin, slugs can become jammed inside the cutter, halting production and potentially damaging the expensive cutting tool. This specific 3-inch pin is tailored for use with Walter's high-performance SST Core Cut, ICECUT, and CARBIDE series annular cutters, specifically for deeper hole applications requiring a 3-inch reach.

Industrial MRO professionals understand that the reliability of small accessories dictates the uptime of larger machinery. By using genuine Walter pilot pins, you ensure seamless compatibility and robust performance, preventing the downtime associated with bent pins or jammed slugs.
