Value Collection SC84949668 Tool Holder Bushing Type B

Product Description

The VALUE COLLECTION SC84949668 is a Type B rotary tool holder bushing designed for use in drill jig and tooling setups where precise hole guidance and repeatable positioning are required. With a 3/8 inch inside diameter and 3/4 inch outside diameter, this bushing accepts standard tooling shanks and seats securely into a mating jig plate. The length under head measures 1.5 inches, and the head thickness is 0.19 inches. Machinists and toolmakers install this component during fixture assembly or as a replacement in worn jig bushing locations.

This bushing is suited for machine shop and manufacturing environments where drill jig bushings guide cutting tools during production runs. Type B bushings are press-fit or slip-fit into liner bushings or directly into jig plates, depending on the application. Typical installations include drill fixtures, reaming setups, and multi-operation tooling plates used in both prototype and production machining work.

Key Features

• Lightweight at 0.132 pounds for easy handling and fixture weight management

Compatibility

Designed as an OEM-style replacement or new-installation component for rotary tool holder jig bushing applications requiring a Type B configuration with 3/8 inch ID and 3/4 inch OD.

Installation Notes

Installation is typically performed by a machinist or toolmaker during fixture build or maintenance. Before replacing or pressing in a bushing, ensure the jig plate bore is clean, free of burrs, and within the required tolerance for the bushing fit class. Use appropriate press tooling when installing press-fit bushings to avoid damage to the head or bore. Do not hammer directly on the head face without a proper driver.
