Value Collection SC05878947 Type J Tool Holder Bushing

Product Description

The VALUE COLLECTION SC05878947 is a Type J rotary tool holder bushing designed for use in drill jigs, fixture plates, and tooling setups where precise hole location and guided drilling are required. With an inside diameter of 0.3125 inches and an outside diameter of 0.7500 inches, this bushing provides accurate tool guidance for 5/16 inch tooling. The length under head measures 1.5000 inches, and the head thickness is 0.1900 inches. This type of headless-style or headed press-fit bushing is installed by toolmakers, machinists, and fixture builders working in production and job-shop environments.

Type J tool holder bushings are commonly used in drill jig assemblies where renewable or fixed liner bushings guide cutting tools such as drills, reamers, and counterbores. This bushing is suited for applications requiring close-tolerance hole location in metal fabrication, assembly fixtures, and machining setups. The distance between hole centers is 13/16 inches, which aids in fixture layout and spacing calculations during tooling design.

Installation Notes

Tool holder bushings of this type are installed by toolmakers and machinists using a press or arbor press to achieve the required interference fit in the liner or jig plate. Ensure the receiving bore is clean and dimensionally correct before pressing the bushing into place. Do not hammer the bushing directly without a proper driver or press plate, as this can damage the head or distort the bore. Follow applicable shop standards and fixture design specifications during installation.
