05Z017 - Walter Pilot Pin for 2-Inch Annular Cutters & Fein/Nitto Adapters

Precision Alignment and Ejection for Industrial Drilling

The Walter 05Z017 Pilot Pin is a specialized accessory engineered to maximize the performance of your magnetic drilling units, specifically those utilizing Fein or Nitto adapter systems. In the demanding world of industrial metalworking, the accuracy of your hole-making process is contingent not just on the drill motor and cutter, but on the integrity of the guidance system. This pilot pin is meticulously crafted from hardened steel, ground to exact tolerances to ensure a perfect fit within 2-inch depth annular cutters, such as the Walter SST Core Cut and Icecut series.

The role of the pilot pin extends far beyond simple alignment. While its primary initial function is to position the cutter precisely over the center punch mark, it becomes a critical mechanical component once the drilling begins. As the cutter engages the steel, the pilot pin retracts into the arbor, opening the internal valve that allows coolant to flow directly to the cutting teeth. This internal lubrication is vital for maintaining the temper of the cutter and ensuring a clean, burr-free finish. Without a properly functioning pilot pin, coolant delivery can be compromised, leading to premature tool failure.

Furthermore, the 05Z017 is designed to eliminate one of the most common frustrations in annular cutting: the stuck slug. Upon completion of the hole, the spring-loaded mechanism behind the pin drives it forward, forcefully ejecting the metal slug from the center of the cutter. This automatic ejection reduces downtime between holes and prevents the operator from having to manually pry hot metal debris from the tool, enhancing both safety and productivity. Whether you are fabricating structural steel or performing maintenance repairs, relying on genuine Walter accessories ensures your equipment operates at peak efficiency.

Technical Compatibility

This pin is specifically dimensioned for cutters with a 2-inch cutting depth. It is essential to match the pilot pin length to the cutter length; using a pin that is too short will fail to center the tool or eject the slug, while a pin that is too long may prevent the cutter from reaching full depth. The 05Z017 is the correct specification for deep-hole applications using the Fein/Nitto interface.
