Global Cnc Industries 8614C .500 Type C Tool Holder Bushing

Product Description

The GLOBAL CNC INDUSTRIES 8614C .500 is a Type C rotary tool holder bushing designed for use in machine tool setups where precise radial location of rotating tooling is required. With a 0.500 inch inside diameter and a 1.750 inch outside diameter, this bushing provides accurate tool guidance in drill jig and fixture applications. The 3.500 inch length under head accommodates deeper workpiece sections, while the 0.2950 inch head thickness seats the bushing securely against the jig plate. Machinists, toolmakers, and fixture builders install this component when building or servicing drill jigs, boring fixtures, and similar precision workholding setups.

This bushing is suited for production and job-shop environments where repeatable hole location is critical. The Type C designation indicates a slip-fixed style with a head, making it appropriate for applications that require the bushing to be retained within a liner bushing or directly pressed into a fixture plate. The 3.125 inch slot length allows for chip clearance and coolant flow during drilling or reaming operations. It is a standard catalog item used across a wide range of metalworking industries including aerospace, automotive, and general machining.

Key Features

• Type C bushing configuration with a head for positive seating in fixture plates
• 0.500 inch inside diameter for half-inch tooling guidance
• 1.750 inch outside diameter for use in standard liner bushing bores
• 3.500 inch length under head supports deep-reach fixture applications
• 3.125 inch slot length promotes chip and coolant clearance during operation
• 0.2950 inch head thickness provides a stable, low-profile seating surface

Compatibility

Designed as an OEM-style replacement or direct-fit component for Type C rotary tool holder bushing applications in standard drill jig and machining fixture assemblies.

Installation Notes

Installation is typically performed by a toolmaker or machinist during fixture assembly or maintenance. The mating bore and liner bushing should be inspected for wear and cleaned before installation. Press-fit or slip-fit installation should follow fixture design tolerances - do not force the bushing into an undersized bore without verifying fit class. Ensure all machine power is locked out and the fixture is fully secured before servicing any tooling components.
