Value Collection SC84949742 Type B Rotary Tool Holder Bushing

Product Description

The VALUE COLLECTION SC84949742 is a Type B rotary tool holder bushing used in drill jig and tooling setups to locate and guide cutting tools with precision. With a 0.75 inch inside diameter and a 1.25 inch outside diameter, this bushing fits standard jig plate bores and accepts common drill, reamer, and boring tool shanks. The head thickness measures 0.265 inches, and the length under the head is 2.125 inches, making it suited for moderate-depth tooling applications. Machinists, toolmakers, and CNC setup technicians install this type of bushing in production fixtures, drill jigs, and custom workholding assemblies where repeatable tool guidance is required.

Type B tool holder bushings are used in metalworking and machining environments where a headless or headed slip-renewable bushing style is needed for guided drilling, reaming, or boring operations. This bushing is appropriate for shop-floor production tooling, inspection fixtures, and prototype jig builds in both job shop and manufacturing settings. It is installed in a mating liner bushing or directly into a hardened jig plate to maintain positional accuracy across repeated cycles.

Key Features

• Type B bushing configuration for use with standard rotary tool holder systems
• Inside diameter of 0.75 inches accommodates common cutting tool shank sizes
• Outside diameter of 1.25 inches for fit into standard liner bushings or jig plate bores
• Length under head of 2.125 inches provides sufficient tool guidance depth
• Head thickness of 0.265 inches for positive seating against the jig plate surface
• Packaged individually for single-unit replacement or tooling builds

Compatibility

Designed as a standard Type B rotary tool holder bushing for use in drill jig assemblies and tooling fixtures that accept 1.25 inch OD press-fit or slip-renewable bushing bores.

Installation Notes

Tool holder bushings are typically installed by machinists or toolmakers using a bushing press or arbor press to seat the bushing squarely into the jig plate or liner. Ensure the mating bore is clean and within tolerance before pressing to avoid damage to the bushing or the fixture plate. Power down and de-energize any machine tool before servicing or replacing tooling components. Follow shop safety procedures and applicable OSHA machining standards during installation.
