Value Collection SC84950161 Tool Holder Bushing Type B

Product Description

The VALUE COLLECTION SC84950161 is a Type B rotary tool holder bushing designed to locate and support cutting tools in drill jigs, fixtures, and precision machining setups. With an inside diameter of 1.25 inches and an outside diameter of 3.5 inches, this bushing provides a secure bore interface for tooling while the 5.25-inch length under the head delivers ample guiding depth for deep-hole or extended-reach applications. The head measures 0.365 inches thick, providing a solid seating surface against the jig plate. This component is installed by machinists and tooling specialists working in production or job-shop environments.

Type B tool holder bushings are commonly used in drill jig assemblies where a press-fit liner bushing or slip-renewable configuration is required. The 3.5-inch outside diameter suits larger jig plate bores, making this bushing appropriate for heavy-duty fixtures handling large-diameter tooling. It is suited for use in metalworking, manufacturing, and machine shop applications where precise tool guidance and repeatable positioning are critical to part quality.

Key Features

• Type B configuration for use in standard rotary tool holder bushing applications
• 1.25-inch inside diameter for large-bore tool guidance
• 3.5-inch outside diameter for press or slip fit into jig plate bores
• 5.25-inch length under head provides extended guiding depth for deep-reach tooling
• 0.365-inch head thickness ensures solid seating and axial location against the fixture face
• Weighs 2.464 pounds, indicating robust, heavy-duty construction

Compatibility

Designed as an OEM-style replacement or direct-fit component for rotary tool holder bushing applications requiring a Type B bushing with a 1.25-inch ID and 3.5-inch OD.

Installation Notes

Installation is performed by machinists or tooling technicians. Ensure the jig plate bore is clean and dimensionally verified before pressing or seating the bushing. Power down all associated machinery and secure the workpiece fixture before servicing or replacing bushings. Do not force-fit the bushing with impact tools, as this can damage the bore or alter the bushing geometry.
