93SE001 - 3-Inch Depth Annular Cutter Pilot Pin

Precision Centering and Ejection for Deep Hole Drilling

The 93SE001 Annular Cutter Pilot Pin is a critical accessory designed to maximize the performance and longevity of your annular cutters. Engineered specifically for cutters with a 3-inch depth of cut, this pilot pin serves multiple essential functions in the magnetic drilling process. Its primary role is to locate the center of the hole, allowing the operator to position the machine with pinpoint accuracy before the motor is engaged. This ensures that every hole is drilled exactly where intended, reducing scrap and rework in metal fabrication tasks.

Beyond simple alignment, this pilot pin is integral to the internal cooling system of modern annular cutters. When the pilot pin is depressed during the drilling operation, it opens a valve within the arbor, allowing coolant to flow down the center of the cutter and reach the cutting teeth directly. This internal lubrication is vital for deep hole drilling—especially at a 3-inch depth—as it prevents overheating, flushes away chips, and significantly extends the life of the cutter. Without a functioning pilot pin, coolant delivery may be compromised, leading to premature tool failure.

Finally, the 93SE001 acts as a powerful slug ejector. Upon completion of the cut, the spring-loaded mechanism behind the pin forces the solid slug out of the cutter. This automatic ejection saves valuable time between holes, as the operator does not need to manually pry the slug loose. Designed for durability and repeated use, this pilot pin is the perfect companion for the 93SE148 cutter and other compatible 3-inch depth tooling. Whether working on structural steel, heavy plate, or pipe, this simple yet effective component ensures your magnetic drill operates at peak efficiency.
