Value Collection SC84949890 Tool Holder Bushing Type B

Product Description

The VALUE COLLECTION SC84949890 is a Type B rotary tool holder bushing designed for use in drill press and machining setups where precise bore alignment is required. With a 1.500-inch inside diameter and a 1.750-inch outside diameter, this bushing provides a secure, repeatable guide for cutting tools and drill bits. The head measures 0.295 inches thick, and the length under the head is 3.000 inches. At 1.914 pounds, this is a solid, heavy-duty component intended for installation by machinists and tool-room technicians working with rotary tooling fixtures.

This Type B tool holder bushing is suited for production drilling, jig boring, and fixture-based machining operations in industrial and job-shop environments. It is used in applications where the bushing head bears against the jig plate surface and the body extends through the plate to guide the tool. The 3.000-inch body length accommodates thicker jig plates or fixtures requiring extended guidance. Machinists and toolmakers working with standard drill jig assemblies will find this bushing dimensionally consistent with common Type B specifications.

Key Features

• Type B head style with 0.295-inch head thickness for positive seating against jig plate surfaces
• 1.500-inch inside diameter provides consistent tool guidance for matching-diameter drill or boring tools
• 1.750-inch outside diameter for press-fit or slip-fit installation into standard jig plate bores
• 3.000-inch length under head accommodates thicker fixture plates requiring extended tool guidance
• Sold as a single unit with a minimum order quantity of 1

Compatibility

Designed as a standard Type B replacement or new-installation bushing for rotary tool holder jig and fixture assemblies requiring a 1.500-inch ID and 1.750-inch OD configuration.

Installation Notes

Tool holder bushings are installed by machinists and toolmakers using press or hand-fit methods depending on the specified tolerance class. Always confirm the jig plate bore diameter and tolerance before pressing the bushing into place. Ensure the work fixture is fully de-energized and secured before any tooling changes. Do not hammer directly on the bushing head; use an appropriate press arbor or driver to avoid distortion.
