Value Collection SC05880091 Rotary Tool Holder Bushing Lbf

Product Description

The VALUE COLLECTION SC05880091 is a Type LBF rotary tool holder bushing used in machine tool setups to locate and guide cutting tools with precision. It features a 0.375 inch inside diameter, a 1.5 inch outside diameter, and a length under head of 3.1563 inches, with a head thickness of 0.625 inches. This bushing seats into a drill jig or tooling plate and maintains accurate tool positioning during drilling, reaming, or boring operations. Machinists and toolroom technicians install this part when building or servicing jig-and-fixture assemblies on CNC or manual machine tools.

Type LBF bushings are designed for renewable liner bushing applications where the bushing is locked in place during use and can be replaced without disturbing the jig plate. This part is suited for production environments where tooling wears and must be swapped out regularly. Its head design allows positive retention in the liner, preventing rotation or pullout under cutting forces. Typical applications include metalworking production jigs, assembly fixtures, and precision drilling operations in both job-shop and high-volume manufacturing settings.

Key Features

• Type LBF design provides positive locking in renewable liner bushings for secure tool guidance
• Inside diameter of 0.375 inches (3/8 inch) accommodates standard drill and reamer shanks
• Outside diameter of 1.5 inches fits standard liner bushing bores
• Length under head of 3.1563 inches supports deep-hole tooling setups
• Head thickness of 0.625 inches ensures stable seating and positive retention in the liner
• Sold individually, suitable for single-unit replacement or new fixture builds

Compatibility

Designed as a standard Type LBF renewable tool holder bushing for use with compatible liner bushings in drill jig and fixture applications where a 3/8 inch tool bore and 1-1/2 inch outside diameter are required.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Before servicing a jig assembly, ensure the machine is powered down and all tooling is removed from the spindle. The bushing is inserted into the liner by aligning the locking notch and rotating to engage the lock; no press fit is required for renewable-style assemblies. Verify inside diameter clearance against the tool shank specification before installation to confirm proper fit.
