Value Collection SC84949775 Tool Holder Bushing Type B

Product Description

The VALUE COLLECTION SC84949775 is a Type B rotary tool holder bushing used to locate and support cutting tools, boring bars, and similar tooling in rotary tool holders and machine spindles. With a 0.5 inch inside diameter, a 1.5 inch outside diameter, and a 2.5 inch length under the head, this bushing provides a rigid, close-tolerance interface between the tool shank and the holder body. The head thickness of 0.265 inches gives the flange enough bearing surface to seat securely against the holder face. Machinists and toolroom technicians install this type of bushing during tooling setup on lathes, mills, and drill presses.

Type B tool holder bushings are used in machine shop and production tooling applications where a flanged bushing is required to adapt a smaller tool shank to a larger holder bore. This bushing suits both manual and CNC setups where consistent tool positioning is critical. It is appropriate for light to moderate metal-cutting operations in job shops, maintenance shops, and production environments. Install by a qualified machinist or toolroom technician following the machine builder's tooling setup procedures.

Key Features

Compatibility

Designed as an OEM-style replacement or standard fitment bushing for Type B rotary tool holders requiring a 0.5 inch ID, 1.5 inch OD flanged bushing.

Installation Notes

Installation should be performed by a qualified machinist or toolroom technician with the machine fully powered down and all spindle motion stopped before handling tooling components. Verify that the holder bore and bushing OD are clean and free of chips or burrs before seating the bushing. Use appropriate arbor press or hand pressure only - do not strike the bushing with a hammer, as this can damage the bore or flange seating surface. Follow the machine builder's torque and retention specifications for the tool holder drawbar or retention knob.
