Value Collection SC84949502 Type J Tool Holder Bushing

Product Description

The VALUE COLLECTION SC84949502 is a Type J rotary tool holder bushing used in drill press and machine tool setups to locate and support cutting tools within a jig or fixture. With a 2 inch inside diameter and a 2.5 inch outside diameter, this bushing provides precise tool guidance for boring, reaming, and drilling operations. The head thickness measures 0.3504 inches and the length under the head is 4 inches, giving machinists and tool-and-die professionals the clearance and depth needed for demanding metalworking applications. Weighing 2.31 pounds, this is a solid, production-grade component intended for shop floor use.

Type J tool holder bushings are commonly used in jig boring and production drilling fixtures where a headed bushing is required to seat flush against a jig plate or fixture body. This bushing fits applications where the 1.75 inch hole center distance and 0.875 inch slot dimension are called out in the fixture design. It is appropriate for both light-production and high-volume machining environments. Installation is handled by machinists, tool makers, or fixture builders working in metalworking shops and manufacturing facilities.

Key Features

Compatibility

Designed as an OEM-style replacement or direct-fit component for standard Type J rotary tool holder bushing applications in jig and fixture assemblies requiring a 2 inch ID and 2.5 inch OD headed bushing.

Installation Notes

Installation is performed by qualified machinists or tool makers. Verify bore tolerances in the fixture plate before pressing or sliding the bushing into position to ensure correct fit class. Power down and lock out all machine tools before servicing or replacing bushings in any active fixture. Do not force the bushing into an undersized bore without proper reaming to the specified dimension.
