05Z019 - Walter Pilot Pin for 1-1/2 Inch Depth Annular Cutters (< 3/4 Inch Dia)

Precision and Durability with Walter Center Pins

The Walter 05Z019 Center Pin is a critical component for achieving high-performance results with annular cutters. Designed specifically for cutters with a drilling depth of 1-1/2 inches and diameters smaller than 3/4 inch, this pilot pin serves multiple essential functions in the magnetic drilling process. First and foremost, it acts as the primary guide, allowing operators to position the cutter exactly over the center punch mark on the workpiece. This precision is vital for structural steel applications where hole tolerance is strict.

Constructed from meticulously hardened steel, the 05Z019 is precision-ground to tight tolerances. This hardening process ensures that the pin resists bending and deformation, even when subjected to the high pressures of heavy-duty drilling. A bent pilot pin can lead to cutter misalignment, breakage, or poor hole quality, making the durability of this Walter accessory a key factor in maintaining your tooling inventory.

Beyond positioning, this center pin is the mechanism responsible for coolant management and slug ejection. In compatible arbor systems, the pin retracts as drilling commences, opening the internal valve to allow coolant to flow directly to the cutting teeth. Upon completion of the hole, the spring-loaded pin forcefully ejects the metal slug, clearing the cutter for the next operation immediately. Without a functioning pilot pin, operators face the time-consuming and hazardous task of manually removing hot, sharp metal slugs.
