Value Collection SC05880000 Rotary Tool Holder Bushing Lb

Product Description

The VALUE COLLECTION SC05880000 is a Type LB rotary tool holder bushing designed for use in drill jigs and precision tooling setups. It features a 0.250-inch inside diameter and a 1.500-inch outside diameter, with a 3.125-inch length under the head and a 0.375-inch head thickness. This style of liner bushing is used to guide cutting tools such as drills, reamers, and boring tools with repeatable accuracy. It is installed by machinists and toolroom technicians working with jig-and-fixture systems in production and job-shop environments.

Type LB liner bushings are press-fit or slip-fit into a drill jig body and serve as a renewable guide element for rotating cutting tools. This bushing suits applications where a head-style bushing is required to positively locate the bushing in the jig plate and resist axial pullout during tool retraction. It is appropriate for use in both dedicated production jigs and general-purpose fixture setups where consistent hole location is critical.

Key Features

• Type LB head-style liner bushing for positive axial retention in jig plates
• 0.250-inch inside diameter for guiding quarter-inch shank cutting tools
• 1.500-inch outside diameter for a stable, rigid fit in the jig body bore
• 3.125-inch length under the head provides extended tool guidance for deep-hole applications
• 0.375-inch head thickness adds a robust seating surface against the jig plate face

Compatibility

Designed as an OEM-style replacement or standard-specification Type LB liner bushing for use in drill jigs and tooling fixtures that accept a 1.500-inch outside diameter head-style bushing with a 0.250-inch bore.

Installation Notes

Installation is typically performed by a machinist or toolroom technician. Ensure the jig plate bore is clean and dimensioned to the correct tolerance before pressing or fitting the bushing. Power down and lock out any machine the jig is mounted to before inserting or removing bushings. Do not use a bushing with a worn or oversized ID, as this will compromise hole location accuracy.
