05Z023 - Walter 1-Inch Arbor Extension for Annular Cutters

Precision Engineering for Deep Hole Drilling

The Walter 05Z023 Extension for Core Cutters is a specialized tooling accessory designed to expand the capabilities of standard annular cutters. In industrial metalworking, operators frequently encounter scenarios where the material thickness exceeds the flute length or reach of standard core cutters. Rather than investing in costly, custom-length tooling which often has long lead times, the 05Z023 provides an immediate, engineering-grade solution. By adding exactly one inch of reach to the assembly, this arbor adaptor allows for the penetration of thicker workpieces or the bridging of gaps in structural assemblies without compromising the rigidity of the setup.

Manufactured from high-grade hardened steel, this extension is built to withstand the significant torque and shear forces generated during heavy-duty magnetic drilling operations. A critical aspect of any extension in a rotational assembly is concentricity; Walter has precision-machined this component to ensure zero run-out. This is vital because even microscopic deviations at high RPMs can lead to cutter chatter, premature wear, or catastrophic shattering of the carbide or HSS cutter teeth. The 05Z023 maintains the strict alignment required for smooth cutting action and high-quality hole finishes.

This extension is fully compatible with Walter’s renowned line of core cutters, including the SST and ICECUT series. It integrates seamlessly with the arbor of magnetic drilling units, providing a secure mechanical lock that transmits power efficiently. For MRO professionals and machinists, this tool represents a strategic addition to the tool crib, transforming standard inventory into deep-hole capable tooling instantly. It is an essential component for structural steel fabrication, heavy equipment repair, and any application requiring versatile drilling depths.
