Value Collection SC84949585 Tool Holder Bushing Type J

Product Description

The VALUE COLLECTION SC84949585 is a Type J rotary tool holder bushing used to locate and support cutting tools in drill jigs and tooling fixtures. With a 2.5-inch inside diameter and a 3-inch outside diameter, it accepts larger-shank rotary tools and fits into corresponding jig bodies with a secure press or slip fit. The head is 0.365 inches thick, and the length under the head measures 4.5 inches, making it suited for deeper tooling setups. Machinists, tool-and-die makers, and production floor technicians install these bushings to maintain precise tool alignment during drilling, reaming, or boring operations.

This Type J bushing is intended for use in industrial machining environments where repeatable hole location is critical. Type J bushings are headless-style slip-renewable or press-fit components used in standard drill jig assemblies. The 4.5-inch length under the head accommodates thicker workpiece fixtures or stacked jig plates. Typical applications include production drilling fixtures, reaming jigs, and multi-spindle tooling setups in both job-shop and high-volume manufacturing settings.

Key Features

• Type J bushing geometry with a 0.365-inch thick head for positive axial seating
• 2.5-inch inside diameter accommodates large-shank rotary tools
• 3-inch outside diameter for corresponding jig plate bore fitment
• 4.5-inch length under the head suits deep fixture and stacked-plate setups
• Weighs 2.464 pounds — substantial steel construction for rigidity under cutting loads
• UNSPSC Code 27112809 for procurement and catalog classification

Compatibility

Designed as a standard Type J tool holder bushing for use in drill jig assemblies and machining fixtures requiring a 3-inch OD bore and a 2.5-inch ID tool passage.

Installation Notes

Tool holder bushings are installed by machinists or tooling engineers during fixture build or maintenance. Press-fit bushings should be installed using an arbor press to avoid damage to the bushing bore or jig plate. Slip-renewable types should be secured with the appropriate locking mechanism before any cutting operation begins. Always verify bore alignment with the fixture plate before final seating to maintain positional accuracy.
