Value Collection SC84949692 Type B Tool Holder Bushing

Product Description

The VALUE COLLECTION SC84949692 is a Type B rotary tool holder bushing designed for use in drill jigs and tooling fixtures where precise bore alignment and repeatable part location are required. With an inside diameter of 0.625 inches and an outside diameter of 1.0000 inches, this bushing provides a close-tolerance guide for cutting tools during machining operations. The head thickness measures 0.265 inches, and the length under head is 1.750 inches. It is installed and serviced by machinists, toolmakers, and production setup personnel working on jig-and-fixture assemblies.

This Type B bushing is suited for use in drill jig plates and fixture bodies where a head-style bushing is required to seat flush against or stand proud of the jig plate surface. The head prevents the bushing from being pushed through the plate during tool entry and provides a positive stop during installation. It is commonly found in production machining environments, job shops, and tool rooms handling repetitive hole-location operations.

Key Features

• Type B head-style bushing provides a positive stop against the jig plate surface
• Inside diameter of 0.6250 inches for close-tolerance tool guidance
• Outside diameter of 1.0000 inches for standard jig plate bore fitment
• Length under head of 1.750 inches accommodates typical jig plate thicknesses
• Head thickness of 0.265 inches for secure seating and minimal deflection

Compatibility

Designed as an OEM-style replacement or standard fitment for Type B drill jig bushing applications requiring a 5/8 inch ID and 1 inch OD configuration.

Installation Notes

Installation of drill jig bushings is typically performed by machinists or toolmakers using a bushing press or arbor press to avoid damage to the bore and head seating surface. Power to any associated machine tool must be locked out before servicing or replacing bushings in a fixture. Do not drive bushings with a hammer directly on the head face, as this may deform the head or alter bore concentricity. Verify bore-to-bushing fit class before pressing to ensure proper retention.
