Value Collection SC84949460 Type J Tool Holder Bushing

Product Description

The VALUE COLLECTION SC84949460 is a Type J rotary tool holder bushing designed for use in drill press and machining center tooling setups. With a 1 inch inside diameter, 2.5 inch outside diameter, and a 4 inch length under the head, this bushing provides accurate alignment and support for rotating tooling. The head thickness measures 0.3504 inches. At 2.31 pounds, it is built with the mass appropriate for stable tool guidance under continuous machining loads. This part is installed by machinists, toolroom technicians, and CNC setup personnel working in production and job-shop environments.

Type J tool holder bushings are used in jig boring, drill press, and machining center applications where precise tool alignment and repeatable positioning are required. This bushing fits into a mating tool holder or jig plate, guiding the cutting tool along the correct axis. The 1-3/4 inch distance between hole centers and the 7/8 inch D-In dimension provide standard fitment geometry for typical Type J tooling configurations. It is suitable for both production runs and prototype work in metal fabrication and precision machining.

Key Features

• Type J bushing geometry with 1 inch ID for standard cutting tool shanks
• 2.5 inch outside diameter for secure seating in mating holder or jig plate
• 4 inch length under head provides extended tool guidance and support depth
• Head thickness of 0.3504 inches for proper seating against the tooling surface
• 1-3/4 inch distance between hole centers for standard Type J tooling layout
• 2.31 pound construction supports stable performance under machining loads

Compatibility

Designed as an OEM-style replacement or direct-fit bushing for standard Type J rotary tool holder applications in drill press and machining center tooling systems.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Power down and lock out the machine before inserting or removing the bushing from the tool holder or jig plate. Ensure the mating bore is clean and free of debris before seating the bushing to achieve proper alignment. Verify inside and outside diameter tolerances against the machine tooling specifications before final installation.
