Value Collection SC05880034 Rotary Tool Holder Bushing Lb

Product Description

The VALUE COLLECTION SC05880034 is a Type LB rotary tool holder bushing designed for use in drill jigs and precision machining setups. It provides a hardened, close-tolerance bore that guides cutting tools accurately during repetitive drilling, reaming, or boring operations. The bushing measures 0.625 inches inside diameter, 1.5 inches outside diameter, and 3.125 inches in length under the head, with a head thickness of 0.375 inches. At 2.222 pounds, this is a solid, durable component suited for production tooling environments where positional accuracy is critical. Machinists, tool-and-die makers, and fixture builders are the typical installers.

Type LB drill bushings are used in fixed jig plates for production drilling and reaming applications in both light and heavy manufacturing. The 5/8 inch bore accommodates drill shanks, reamers, and boring tools of that diameter, while the 1.5 inch OD provides a secure press-fit or slip-fit interface with the jig liner bushing. The 3.125 inch length under the head makes this bushing appropriate for setups requiring extended tool guidance through thicker jig bodies or for work requiring additional chip clearance between the bushing face and the workpiece.

Key Features

• Type LB configuration with a flanged head for positive axial positioning in the jig plate
• 0.625 inch inside diameter for use with matching drill or reamer shanks
• 1.5 inch outside diameter for standard liner bushing compatibility
• 3.125 inch length under head provides extended tool guidance for thicker fixtures
• 0.375 inch head thickness adds rigidity and secure seating against the jig surface
• 2.222 pound construction indicates a robust, full-body bushing suitable for production use

Compatibility

Designed as an OEM-style replacement or direct-fit component for drill jig setups requiring a Type LB liner bushing with a 5/8 inch bore and 1-1/2 inch outside diameter.

Installation Notes

Installation is typically performed by a machinist or toolmaker using a bushing press or arbor press to seat the bushing into the liner or jig plate bore. Ensure the mating bore in the jig plate is clean, free of burrs, and dimensionally correct before pressing. De-energize or lock out any machine the jig is mounted to before servicing tool holders or bushings. Do not hammer bushings directly without a proper driver to avoid damage to the head or bore.
