Value Collection SC84949858 Type B Tool Holder Bushing

Product Description

The VALUE COLLECTION SC84949858 is a Type B rotary tool holder bushing designed for use in drill jigs, tool holders, and precision machining fixtures. With a 0.75 inch inside diameter and a 1.75 inch outside diameter, this bushing guides cutting tools accurately during drilling, reaming, and boring operations. The head measures 0.295 inches thick, and the length under head is 3 inches. Weighing 1.914 pounds, this bushing is built for repeated industrial use. It is installed by machinists, tool-and-die workers, and precision fabricators who require consistent tool guidance and repeatability across production runs.

This Type B bushing is suited for use in jig plates and fixture assemblies in both production and job-shop environments. Type B bushings are typically press-fit or installed into liner bushings within a drill jig plate, providing a renewable wear surface that guides drills, reamers, or other rotary cutting tools to a precise location. The 3 inch length under head accommodates thicker workpieces or deeper jig plates where additional tool guidance depth is required.

Key Features

• Type B bushing design for use in standard drill jig and tool holder assemblies
• 0.75 inch inside diameter and 1.75 inch outside diameter for precise tool guidance
• 3 inch length under head accommodates deeper jig plates and thicker workpieces
• 0.295 inch head thickness provides a secure seating surface within the fixture
• Solid construction at 1.914 pounds supports high-repetition machining applications

Compatibility

Designed as an OEM-style replacement or direct fitment bushing for standard Type B rotary tool holder and drill jig applications requiring a 0.75 inch ID, 1.75 inch OD, and 3 inch length under head.

Installation Notes

Installation is typically performed by machinists or toolmakers during jig assembly or bushing replacement. The mating bore in the jig plate or liner bushing should be verified for correct tolerance fit before pressing the bushing into place. Ensure the jig or fixture is fully secured and all rotating equipment is powered down before servicing or replacing a bushing. Follow applicable ASME tooling and fixture standards for proper press-fit tolerances and seating procedures.
