Value Collection SC84950203 Rotary Tool Holder Bushing Type B

Product Description

The VALUE COLLECTION SC84950203 is a Type B rotary tool holder bushing designed for use in precision machining and toolholding applications. It features a 2.25-inch inside diameter, a 3.5-inch outside diameter, and a length under head of 5.25 inches. The head thickness measures 0.365 inches. Weighing 2.464 pounds, this bushing provides the dimensional stability and fit required for accurate tool positioning in rotary tool holders. Machinists and toolroom technicians rely on this style of bushing to support and locate rotating tools within machine spindles and holders.

This Type B bushing is suited for use in toolholding setups on mills, lathes, and similar machine tool equipment where a press or slip fit is required between the holder and the cutting tool shank. It is appropriate for both production floor and toolroom environments. The 2.25-inch bore accommodates tool shanks of that diameter, while the 3.5-inch OD fits corresponding holder bores. Sold individually, it is a straightforward replacement or new-installation component for shops maintaining or expanding their toolholding inventory.

Compatibility

Designed as an OEM-style replacement or direct-fit component for rotary tool holder assemblies requiring a Type B bushing with a 2.25-inch ID and 3.5-inch OD.

Installation Notes

Installation is typically performed by a machinist or toolroom technician. Before installing or removing a tool holder bushing, ensure the machine spindle is fully powered down and locked out per applicable OSHA lockout/tagout procedures. Clean the holder bore and bushing OD thoroughly before fitting to ensure proper seating and dimensional accuracy. Do not force the bushing if resistance is encountered — verify bore and OD dimensions against the holder specifications before pressing or driving into place.
