Value Collection SC84950047 Rotary Tool Holder Bushing

Product Description

The Value Collection SC84950047 is a Type B rotary tool holder bushing designed for use in precision machining and toolholding applications. It features a 1.5-inch inside diameter and a 2.5-inch outside diameter, with a 4-inch length under the head and a head thickness of 0.334 inches. The bushing serves as a bore-reduction liner within rotary tool holders, maintaining accurate tool positioning and minimizing runout during machining operations. Machinists and toolroom technicians install this component in CNC and manual machine setups where controlled bore sizing is required.

This bushing is suited for use in toolholding systems that accept a 2.5-inch OD body and require a 1.5-inch ID bore. Typical installation scenarios include turret toolholders, boring bars, and rotary holder assemblies on lathes and machining centers. The 4-inch length under the head provides sufficient engagement depth for stable support in moderate-depth holder pockets.

Key Features

• Type B bushing configuration for compatibility with standard rotary toolholder systems
• 1.5-inch inside diameter for accurate bore reduction and tool positioning
• 2.5-inch outside diameter for secure fit within the holder bore
• 4-inch length under head for stable engagement in deeper holder pockets
• 0.334-inch head thickness provides positive axial stop and seating surface
• Weighs 2.288 pounds, indicating a robust, solid construction suitable for production use

Compatibility

Designed as a direct-fit Type B rotary tool holder bushing for toolholding assemblies requiring a 2.5-inch OD and 1.5-inch ID bore configuration. Consult the toolholder manufacturer specifications to confirm fitment before installation.

Installation Notes

Installation is typically performed by a machinist or toolroom technician. Ensure the machine spindle is fully powered down and all stored energy is released before accessing the toolholder assembly. Clean the bore and bushing surfaces before seating to avoid misalignment or galling. Do not force-fit the bushing; confirm bore tolerances match before pressing or driving into place.
