Value Collection SC84949684 Type B Tool Holder Bushing

Product Description

The VALUE COLLECTION SC84949684 is a Type B rotary tool holder bushing designed for use in drill jigs, fixtures, and precision tooling setups. It features an inside diameter of 0.5000 inches, an outside diameter of 1.0000 inches, and a length under head of 1.7500 inches, with a head thickness of 0.2650 inches. This bushing guides cutting tools such as drills, reamers, and boring bars during machining operations, providing accurate tool location and reducing workpiece drift. Machinists and toolroom technicians install this component in production and prototype fixturing environments where repeatable hole location is required.

This Type B press-fit style bushing is suited for drill jig applications in both job-shop and production machining environments. It is used where a flanged head is required to control the depth of insertion into the jig plate and to provide a positive stop against the fixture surface. Typical installations involve metal fabrication shops, machine shops, and tooling departments working with ferrous and non-ferrous materials. The bushing is installed into a prepared jig plate bore and serves as a renewable liner to extend fixture service life.

Key Features

• Type B flanged bushing with a 0.2650-inch head thickness for positive depth control
• Inside diameter of 0.5000 inches for 1/2-inch tool shanks and drill bodies
• Outside diameter of 1.0000 inches for standard jig plate bore fitment
• Length under head of 1.7500 inches provides ample tool guidance through thick fixture plates
• Compact package quantity of one allows single-piece procurement for repair or prototype work

Compatibility

Designed as an OEM-style replacement or direct-fit component for Type B rotary tool holder bushing applications in standard drill jig and fixture assemblies.

Installation Notes

Installation is typically performed by a machinist or toolroom technician. The receiving bore in the jig plate should be finish-reamed to the appropriate tolerance for a press fit before the bushing is driven or pressed into place. Ensure the fixture is secured and free of chips or debris before installation. Do not hammer directly on the bushing head; use a driver block or arbor press to seat the bushing evenly and avoid deformation.
