Value Collection SC84949445 Type J Tool Holder Bushing

Product Description

The VALUE COLLECTION SC84949445 is a Type J rotary tool holder bushing designed for use in drill presses, jig borers, and machining centers where precise tool location and support are required. This bushing 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 demand secure, concentric tool guidance. The head thickness measures 0.3504 inches. At 2.31 pounds, this is a solid, heavy-duty component intended for professional machine shop and industrial tooling setups. Installation and changeover are handled by machinists and tooling technicians.

Type J tool holder bushings are commonly used in fixed and renewable bushing plate assemblies found in production drilling and boring operations. The 1.75 inch distance between hole centers is a standard dimension that aligns with common jig plate configurations. This bushing is appropriate for both light production runs and repetitive high-volume drilling operations where tool alignment consistency is critical to part quality and throughput.

Key Features

• Type J bushing geometry for compatibility with standard tool holder plate systems
• 0.75 inch inside diameter for precise tool or liner fit
• 2.5 inch outside diameter provides stable seating in the bushing plate
• 4 inch length under head supports deep-reach tooling applications
• 0.3504 inch head thickness for positive axial location against the plate face
• 2.31 pound solid construction suited for sustained industrial use

Compatibility

Designed as an OEM-style replacement or direct-fit component for Type J rotary tool holder bushing applications in standard drill jig and tooling plate assemblies.

Installation Notes

Installation is performed by qualified machinists or tooling technicians. Ensure the bushing plate bore and mating surfaces are clean and free of burrs before pressing or seating the bushing. Power down and lock out all machine energy sources before servicing any tooling or bushing plate components. Do not force-fit the bushing with impact tools, as this may damage the bore or alter the bushing geometry.
