Value Collection SC05878970 Type J Tool Holder Bushing

Product Description

The VALUE COLLECTION SC05878970 is a Type J rotary tool holder bushing designed for use in drill jigs, fixture plates, and precision machining setups. With an inside diameter of 0.375 inches and an outside diameter of 1.0000 inches, this bushing guides rotating tools such as drills, reamers, and boring bars with repeatable accuracy. The length under head measures 1.75 inches, and the head thickness is 0.2650 inches. It is installed and serviced by machinists, toolmakers, and maintenance technicians working in production or job-shop environments.

This bushing is suited for applications requiring a press-fit or slip-fit tool guide in jig and fixture work. Type J designation indicates a specific head and body geometry used in standard drill jig applications. The 7/8 inch distance between hole centers and the 7/16 inch D-In dimension support standard tooling layouts. It is appropriate for both light production runs and repetitive-operation fixtures in metalworking and general manufacturing environments.

Installation Notes

Installation of drill jig bushings is performed by qualified machinists or toolmakers. Power down and lock out all machine spindles before inserting or removing bushings from a fixture plate. Press-fit bushings require an arbor press and proper alignment to avoid cocking or galling the bore. Verify inside diameter clearance against the tool shank before installation to ensure correct fit class.
