Value Collection SC84950005 Type B Tool Holder Bushing

Product Description

The VALUE COLLECTION SC84950005 is a Type B rotary tool holder bushing designed for use in drill jigs, fixture plates, and machine tool setups. It features a 0.75-inch inside diameter, a 2.5-inch outside diameter, and a 4-inch length under the head, making it suited for applications that require a positive-stop shoulder to locate the bushing at a fixed depth. The head thickness measures 0.334 inches. Weighing approximately 2.288 pounds, this bushing provides the mass and rigidity expected in precision tooling components. Machinists, toolmakers, and fixture builders are the primary installers of this component.

Type B tool holder bushings are commonly used in CNC machining centers, drill press fixtures, and production jig setups where a flanged head is required to prevent the bushing from pulling through the fixture plate. The flanged shoulder seats against the top face of the jig plate, providing consistent depth registration for cutting tools. This bushing is appropriate for both one-off prototype fixtures and high-volume production tooling environments.

Key Features

• Type B flanged head design for positive depth registration in jig plates
• 0.75-inch inside diameter accommodates standard tooling shanks
• 2.5-inch outside diameter for press-fit or slip-fit installation into fixture bores
• 4-inch length under the head suits thick fixture plates and extended reach applications
• 0.334-inch head thickness provides a stable seating flange

Compatibility

Designed as an OEM-style replacement or direct-fit component for drill jig and machine tool fixture setups requiring a Type B flanged rotary tool holder bushing with a 0.75-inch inside diameter and 2.5-inch outside diameter.

Installation Notes

Installation is typically performed by a machinist or toolmaker using a bushing press or arbor press to achieve the correct interference or slip fit within the fixture plate bore. Ensure the mating bore in the jig plate is machined to the appropriate tolerance before pressing or seating the bushing. Power down all associated machinery and secure the workpiece before performing any fixture assembly or bushing replacement work.
