Global Cnc Industries 8616C 1.000 Tool Holder Bushing Type C

Product Description

The GLOBAL CNC INDUSTRIES 8616C 1.000 is a Type C rotary tool holder bushing designed for use in machine tool setups where precise bore alignment and secure tool retention are required. With a 1 inch inside diameter, 2.5 inch outside diameter, and a 4.5 inch length under head, this bushing is built to fit standard tooling bores in CNC and manual machining environments. The head thickness measures 0.333 inches, and the slot runs 4.125 inches in length. Machinists and toolroom technicians install this type of bushing to locate and support rotating tools within drill jigs, fixture plates, and tool holder bodies.

This bushing is suited for machine shop and industrial manufacturing applications where Type C bushing geometry is specified. It is a standard catalog item used in jig boring, drilling, and reaming setups. The 1 inch bore accommodates common tooling shank sizes found in production and job shop environments. Toolroom technicians and CNC setup personnel are the primary installers in both light manufacturing and heavy industrial settings.

Compatibility

Designed as an OEM-style replacement or direct-fit bushing for standard Type C rotary tool holder applications in CNC machining and jig boring setups where a 1 inch ID and 2.5 inch OD bushing is specified.

Installation Notes

Installation is typically performed by a machinist or toolroom technician. Power down and lock out all machine axes and spindle drives before removing or installing any tool holder bushing. Ensure the mating bore and seating surfaces are clean and free of burrs before pressing or sliding the bushing into position. Consult the fixture or machine manufacturer's documentation for any torque or retention hardware requirements specific to the application.
