Product Description

The GLOBAL CNC INDUSTRIES 8612B .625 is a Type B rotary tool holder bushing designed for use in drill presses, milling machines, and CNC tooling setups. It provides a precision bore for locating and supporting rotating tools or workholding components within a tool holder assembly. With an inside diameter of 0.625 inches and an outside diameter of 1.25 inches, this bushing delivers accurate tool alignment in demanding machine shop environments. The 0.265-inch head thickness and 2.125-inch length under head make it suitable for standard Type B bushing pocket applications. Machinists and CNC operators are the primary installers of this component.

This Type B bushing is intended for use in jig and fixture tooling applications found in production machining, job shops, and maintenance operations. It fits standard Type B tool holder bushing seats. The 0.625-inch bore accommodates tooling shanks of that diameter, and the 2.125-inch length under head suits moderate-depth applications. No specific machine model compatibility is stated by the manufacturer for this part.
