Value Collection SC84949783 Type B Tool Holder Bushing

Product Description

The VALUE COLLECTION SC84949783 is a Type B rotary tool holder bushing designed for use in drill jigs, tooling fixtures, and machine tool setups. It features a 0.625 inch inside diameter, a 1.5 inch outside diameter, and a 2.5 inch length under the head, with a head thickness of 0.265 inches. The flanged head seats flush against the jig plate, locating the bushing axially and resisting pull-through under repeated tool passes. Machinists, toolmakers, and fixture builders install this bushing when a guided, renewable drill point is needed to maintain hole location accuracy across production runs.

This bushing is suited for metalworking, fabrication, and production machining environments where repeatable hole positioning is critical. It fits into standard Type B bushing press-fit liners and is appropriate for use in drill jig plates in both job-shop and production settings. The 2.5 inch length under the head provides clearance for chip evacuation and tool travel in deeper workpiece applications.

Key Features

• Type B flanged head design seats and locates positively in the jig plate without additional fasteners
• 0.625 inch inside diameter guides standard drill shanks and reamers accurately
• 1.5 inch outside diameter fits standard Type B press-fit liner bores
• 2.5 inch length under the head accommodates deeper workpiece thicknesses and chip clearance
• 0.265 inch head thickness provides a positive axial stop without excessive protrusion
• Weighs 1.804 pounds, indicating a solid, full-length construction

Compatibility

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

Installation Notes

Installation is typically performed by a toolmaker or machinist using an arbor press to seat the bushing into a pre-machined liner bore. Power down and de-energize all machine tool circuits before pressing or removing bushings from a live fixture. Verify bore diameter and surface finish of the liner to ensure proper press-fit interference and avoid galling. Do not hammer the bushing directly without a proper driver or press plate, as this can damage the head seating surface.
