Global Cnc Industries 8612C .500 Type C Tool Holder Bushing

Product Description

The GLOBAL CNC INDUSTRIES 8612C .500 is a Type C rotary tool holder bushing designed for use in tooling setups that require precise bore alignment and secure tool retention. With a 0.500 inch inside diameter and a 1.250 inch outside diameter, this bushing fits into standard drill jig and tool holder assemblies used in machining operations. The length under head measures 3.250 inches, providing sufficient depth for stable tool engagement. Weighing 0.82 pounds, this bushing is suited for use by machinists and tooling professionals working in production or maintenance machining environments.

This Type C bushing is applied in rotary tool holder systems where a slotted bushing design is required to accommodate a locking key or drive pin. The slot length of 2.875 inches allows for proper engagement in driven or locked bushing configurations. It is typically installed in drill jigs, fixture plates, and machining fixtures in both job shop and production settings. The head thickness of 0.265 inches provides a positive seating surface against the fixture plate face.

Installation Notes

Installation is typically performed by a machinist or tooling technician. Ensure all spindle power is off and the machine is locked out before removing or installing tooling bushings. Verify the mating bore diameter and fixture plate depth match the bushing outside diameter and length under head before pressing or driving the bushing into position. Consult applicable machine tool fixture standards for press-fit tolerances and retention requirements.
