05Z027 - Walter Pilot Pin for 1-Inch Depth Annular Cutters (Small Diameter)

Precision Alignment for Annular Cutters

The Walter 05Z027 Pilot Pin is a critical accessory designed to maximize the performance and lifespan of your annular cutters. Engineered specifically for use with cutters featuring a 1-inch depth of cut and a diameter of less than 3/4 inch, this center pin plays a dual role in the drilling process. First, it acts as a precise positioning guide, allowing operators to align the cutter exactly over the center punch mark on the workpiece. This ensures that every hole is drilled with pinpoint accuracy, reducing waste and rework.

Constructed from high-quality hardened steel, the 05Z027 is ground to exact tolerances. This robust construction prevents bending and wear, ensuring the pin slides smoothly within the cutter body. During the drilling operation, the pin retracts into the arbor, often acting as a flow control valve for internal coolant systems, directing lubrication exactly where it is needed—at the cutting teeth. This thermal management is vital for maintaining the temper of your high-speed steel or carbide-tipped cutters.

Upon completion of the hole, the pilot pin performs its second critical function: slug ejection. Powered by the spring mechanism in the arbor, the pin forcefully pushes the solid metal core (slug) out of the cutter. This automatic ejection eliminates the need for manual removal, speeding up workflow and preventing the dangerous situation of a jammed slug spinning inside the cutter. Whether you are using Walter's ICECUT, SST Core Cut, or Carbide series, this pilot pin is an indispensable component for efficient magnetic drilling operations.

Key Benefits:

• Ensures accurate centering on pre-marked drilling spots.
• Prevents slug jams by automatically ejecting the core after the cut.
• Controls internal coolant flow for optimal cutter lubrication.
• Durable hardened steel resists wear in industrial environments.
