05Z033 - Walter 2-Piece Pilot Pin for 4-Inch Depth Annular Cutters

Precision Guide for Deep Hole Drilling

The Walter 05Z033 is a specialized 2-Piece Pilot Pin designed to support annular cutters with a 4-inch depth of cut (DOC). In industrial magnetic drilling operations, the pilot pin plays a critical role in the functionality of the cutter. It serves three primary functions: centering the cutter over the pre-marked drilling spot, regulating the flow of internal coolant to the cutting edges, and mechanically ejecting the material slug once the hole is complete. For extended depth cutters, such as those reaching 4 inches, a standard single-piece pin is often insufficient or incompatible with standard arbor retraction lengths. This 2-piece design addresses that engineering challenge, allowing for deep boring without compromising the mechanical action of the arbor.

Manufactured from high-grade steel, this pin is expertly hardened and precision ground. This manufacturing process ensures that the pin remains perfectly straight under load and resists wear from repetitive cycling against the workpiece and the internal bore of the cutter. The 05Z033 is specifically engineered for compatibility with Walter's high-performance cutter lines, including SST Core Cut, ICECUT, and CARBIDE series, when used with a 3/4" Weldon shank arbor. It is an essential component for maintaining the accuracy and efficiency of your magnetic drilling equipment.

Reliability in MRO environments is paramount. A bent or worn pilot pin can lead to coolant blockage, slug jams, or inaccurate hole placement. By utilizing the correct OEM specification pin for your 4-inch cutters, you ensure seamless operation and protect your investment in high-value annular cutters.
