Value Collection SC84950153 Tool Holder Bushing Type B

Product Description

The VALUE COLLECTION SC84950153 is a Type B rotary tool holder bushing used in machine tool setups to locate and support cutting tools within a drill jig or fixture. With a 1 inch inside diameter and a 3.5 inch outside diameter, this bushing provides accurate tool guidance during drilling, reaming, or boring operations. The head thickness measures 0.365 inches, and the length under the head is 5.25 inches, making it suited for applications that require extended reach into a workpiece or fixture plate. Machinists and toolroom professionals install this component as part of precision jig and fixture assemblies.

This bushing is designed for use in industrial machining environments where repeatable tool positioning is critical. It fits into prepared jig plate bores and holds cutting tools or drill bushings in alignment during production runs. The Type B designation indicates a specific head and body geometry standardized for tool holder bushing applications. It is appropriate for both short-run and high-volume drilling fixtures where location accuracy directly affects finished part quality.

Key Features

• Type B bushing geometry for standardized jig and fixture compatibility
• 1 inch inside diameter for precise cutting tool or liner bushing fit
• 3.5 inch outside diameter provides a stable seating surface in the fixture plate
• 5.25 inch length under head accommodates deep fixture plates or extended tool guidance requirements
• 0.365 inch head thickness keeps the bushing positively seated against the fixture surface
• Weighs 2.464 pounds, indicating a heavy-duty, solid construction suitable for production use

Compatibility

Designed as a standard Type B tool holder bushing for use in drill jigs and machining fixtures requiring a 1 inch inside diameter and 3.5 inch outside diameter bushing seat.

Installation Notes

Installation is performed by toolroom machinists or fixture builders. The receiving bore in the jig plate should be finish-reamed to the proper press or slip fit tolerance before installing this bushing. Ensure all machinery is powered down and all stored energy is released before working on or near the fixture assembly. Do not force the bushing into an undersized bore, as this can crack the jig plate or distort the bushing bore diameter.
