Global Cnc Industries 8613C .625 Tool Holder Bushing Type C

Product Description

The GLOBAL CNC INDUSTRIES 8613C .625 is a Type C rotary tool holder bushing designed for use in CNC machining and toolroom applications. It features a 0.625 inch inside diameter and a 1.5 inch outside diameter, with a length under head of 3.375 inches. The 3.0 inch slot length accommodates positive drive and orientation in the holder. This bushing provides a precision interface between the rotating tool and the tool holder body, and is typically installed by CNC machinists and toolroom technicians on milling, drilling, or boring machine setups.

Type C tool holder bushings are commonly used in industrial machining environments where repeatable, accurate tool positioning is required. This bushing suits applications on standard CNC machining centers and manual mills that accept the corresponding holder bore size. The 0.265 inch head thickness keeps the bushing properly seated and located within the holder assembly. This part is appropriate for both production and job-shop environments requiring a reliable OEM-style bushing replacement or new installation.

Installation Notes

Installation is performed by qualified CNC machinists or toolroom technicians. Ensure the machine spindle is fully powered down and all stored energy is released before handling tool holder components. Clean the holder bore and bushing surfaces before installation to ensure accurate seating and prevent fretting. Verify that the slot and drive key are properly aligned before securing the assembly in service.
