Value Collection SC84949940 Type B Tool Holder Bushing

Product Description

The VALUE COLLECTION SC84949940 is a Type B rotary tool holder bushing designed for use in machining and toolholding applications. With a 1 inch inside diameter and a 2 inch outside diameter, this bushing provides a precise, stable interface between rotating tool holders and machine spindles or fixture bores. The length under head measures 3.5 inches, and the head thickness is 0.295 inches. Weighing 2.09 pounds, this is a solid, shop-grade component built for demanding production and maintenance environments. Installation is typically performed by machinists or tool room technicians during spindle setup, fixture assembly, or toolholder configuration.

This Type B bushing is suited for use in rotary tool holder setups found in CNC machining centers, manual mills, lathes, and similar machine tool platforms. The 1 inch bore accommodates standard toolholder shanks of that diameter, while the 2 inch OD allows it to seat securely in appropriately sized bores or fixtures. It is a single-piece, sold-individually component intended for direct installation into compatible toolholding systems. Machinists replacing worn or damaged bushings will find the dimensional profile consistent with standard Type B bushing specifications.

Installation Notes

Installation is performed by a qualified machinist or tool room technician. Before installing or removing any toolholder bushing, ensure the machine spindle is fully stopped and locked out per OSHA lockout/tagout procedures. Press or drive the bushing into the bore with appropriate tooling to avoid damage to the seating surface or head. Inspect the bore and mating surfaces for wear, burrs, or contamination before seating the new bushing.
