Value Collection SC99113938 Type J Tool Holder Bushing

Product Description

The VALUE COLLECTION SC99113938 is a Type J rotary tool holder bushing used to locate and support cutting tools in drill jigs, fixtures, and machine tool setups. It features a 0.250 inch inside diameter, a 1.000 inch outside diameter, and a length under head of 1.750 inches. The head thickness measures 0.265 inches. This bushing is installed by machinists, toolmakers, and production setup technicians working with jig boring, drilling, and reaming operations where precise tool guidance is required.

Type J bushings are a standard fixed-liner style used in jig and fixture applications across general machining, metalworking, and production environments. This bushing is suited for applications where a press-fit liner is already installed and a slip-renewable or fixed drill bushing is needed to guide the cutting tool accurately. The 7/8 inch distance between hole centers and 7/16 inch D-In dimension make it compatible with standard jig plate layouts in both prototype and production tooling setups.

Key Features

• Type J bushing configuration for use in standard jig and fixture liner arrangements
• 0.250 inch inside diameter provides precise guidance for 1/4 inch cutting tools
• 1.000 inch outside diameter fits standard liner bore sizes
• 1.750 inch length under head accommodates workpiece thickness and clearance requirements
• 0.265 inch head thickness provides positive seating against the jig plate surface
• 7/8 inch distance between hole centers supports standard multi-hole jig plate layouts

Compatibility

Designed as an OEM-style replacement or direct-fit component for standard Type J drill bushing applications in jig plates and tooling fixtures requiring a 1/4 inch ID and 1 inch OD bushing.

Installation Notes

Installation is typically performed by a machinist or toolmaker using a bushing press or arbor press to seat the component without damage to the bore or head. Ensure the liner bore and mating surfaces are clean and free of burrs before installation. Do not hammer the bushing directly without a proper driver to avoid distorting the ID. Follow applicable shop safety procedures and fixture design standards when integrating into production tooling.
