Global Cnc Industries 8613C .750 Tool Holder Bushing Type C

Product Description

The GLOBAL CNC INDUSTRIES 8613C .750 is a Type C rotary tool holder bushing designed for use in machine tool setups where precise boring bar, drill, or tooling support is required. With an inside diameter of 0.750 inches and an outside diameter of 1.500 inches, this bushing provides accurate tool alignment and stable support during machining operations. The length under head measures 3.375 inches, and the slot length is 3.000 inches, making it suitable for applications that require clearance or chip relief along the shank. Machinists and tooling setup technicians working in CNC and manual machining environments are the primary installers of this component.

This bushing is used in rotary tool holder applications across CNC machining centers, lathes, and manual mill setups in both production and job-shop environments. It is suited for residential and commercial machine shops where standardized tooling bushings are required for repeatable, accurate tool positioning. The Type C designation indicates a specific head and slot configuration compatible with standard tool holder block systems. The head thickness of 0.265 inches ensures a low-profile seating face within the holder body.

Compatibility

Designed as an OEM-style replacement or direct-fit bushing for standard rotary tool holder block systems accepting Type C bushings with a 1.500 inch outside diameter and 0.750 inch inside diameter.

Installation Notes

Installation is performed by a qualified machinist or tooling technician. Always power down and lock out the machine before removing or installing tooling bushings. Ensure the bushing bore and holder block bore are clean and free of chips or burrs before seating the bushing to maintain alignment accuracy. Do not force the bushing into the holder; a proper slip or press fit should be confirmed against the holder specification before assembly.
