Value Collection SC99292740 Type J Tool Holder Bushing

Product Description

The VALUE COLLECTION SC99292740 is a Type J rotary tool holder bushing designed to locate and support cutting tools within tool holders and jig plates on drilling and machining equipment. With an inside diameter of 0.4375 inches and an outside diameter of 1.0000 inches, this bushing provides a precise bore for guiding drill bits, reamers, and similar rotary tooling. The head thickness measures 0.265 inches, and the length under the head is 1.750 inches. Machinists and toolroom technicians install this bushing as a renewable liner in fixed or slip-type tool holder applications where accurate hole location and tool support are critical.

This Type J bushing is suited for use in drill jigs, fixture plates, and production tooling setups found in machine shops, manufacturing facilities, and maintenance environments. It is appropriate for both light-duty and moderate-production drilling operations where a headed bushing style is required to provide a positive stop against the jig plate surface. The distance between hole centers is 7/8 inches, which should be verified against the jig or fixture design before installation.

Key Features

• Type J headed bushing profile provides a positive seating shoulder against the jig plate surface
• Inside diameter of 0.4375 inches for precise tool guidance
• Outside diameter of 1.0000 inches for standard tool holder and jig plate bores
• Head thickness of 0.265 inches for secure retention and flush or proud mounting
• Length under head of 1.750 inches accommodates typical jig plate thickness requirements
• Sold individually, allowing single-piece replacement or incremental tooling builds

Compatibility

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

Installation Notes

Tool holder bushings of this type are typically installed by machinists or toolroom technicians using a press or bushing driver to seat the bushing flush or to the shoulder within the jig plate bore. Power down and lock out all machinery before removing or installing tool holder bushings. Verify bore diameter, length under head, and head thickness against the jig plate specifications before pressing the bushing into place. Do not hammer directly on the head face without a proper driver to avoid distorting the bushing bore.
