05Z028 - Walter Pilot Pin for 1-Inch Depth Annular Cutters

Precision Drilling with Walter Center Pins

The Walter 05Z028 Center Pin is a critical accessory for professionals using magnetic drilling units and annular cutters. Designed to work seamlessly with Walter's high-performance core cutters, this pilot pin serves multiple vital functions that streamline the metal drilling process. Primarily, it acts as a centering guide, allowing the operator to position the drill bit with pinpoint accuracy over the punch mark. This eliminates wandering and ensures that every hole is drilled exactly where intended.

Beyond positioning, the 05Z028 is engineered to manage the flow of lubricant. As the pilot pin retracts into the arbor during the drilling operation, it opens the internal valve to allow coolant to flow directly to the cutting teeth. This targeted lubrication is essential for maintaining the temper of the cutter and achieving a clean, burr-free finish. Once the hole is complete, the spring-loaded pin forcefully ejects the metal slug, clearing the cutter for the next operation immediately. Made from hardened, precision-ground steel, this pin is built to withstand the rigors of heavy industrial use.

Key Benefits:

• Accuracy: Guarantees precise hole placement every time.
• Efficiency: Automates slug removal to reduce downtime between cuts.
• Durability: Hardened steel construction resists bending and wear.
