Value Collection SC84950070 Type B Tool Holder Bushing

Product Description

The VALUE COLLECTION SC84950070 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 2.25-inch inside diameter, 2.5-inch outside diameter, and a 4-inch length under the head, this bushing provides a precise bore for guiding drill bits, reamers, or other rotary tooling. The head thickness measures 0.334 inches. Weighing approximately 2.288 pounds, this bushing is built for repeated use in production drilling and boring operations on the shop floor.

Type B press-fit bushings like this one are standard in jig and fixture work across job shops, tool rooms, and manufacturing facilities. This size is suited for heavy-duty drilling applications where a large-diameter guide bore is needed to maintain positional accuracy. It is typically installed by machinists and toolmakers setting up drill jigs for repetitive hole-location tasks on metal workpieces.

Key Features

• Type B bushing configuration for press-fit installation in drill jig liners
• 2.25-inch inside diameter provides a large-bore guide for rotary tooling
• 2.5-inch outside diameter for secure press-fit retention in the jig plate
• 4-inch length under head offers extended tool guidance along the drill axis
• 0.334-inch head thickness seats flush against the jig plate surface

Compatibility

Designed as a standard Type B press-fit replacement or new-installation bushing for drill jigs and fixtures requiring a 2.25-inch bore guide with a 2.5-inch outside diameter.

Installation Notes

Installation is typically performed by a machinist or toolmaker using a hydraulic or arbor press to seat the bushing into a prepared liner or jig plate bore. Ensure the receiving bore is clean and dimensionally correct before pressing to avoid galling or misalignment. Do not hammer the bushing directly without a proper driver to avoid damage to the head or bore surface. Follow applicable shop standards for press-fit tolerances and jig plate material specifications.
