Value Collection SC97305577 Type B Tool Holder Bushing

Product Description

The VALUE COLLECTION SC97305577 is a Type B rotary tool holder bushing used to locate and support cutting tools in drill jigs, fixtures, and tooling plates. With a 0.375-inch inside diameter, a 1.0000-inch outside diameter, and a length under head of 1.75 inches, it provides precise tool guidance during drilling and reaming operations. The head measures 0.265 inches thick, giving it a positive stop against the jig plate surface. This bushing is handled and installed by machinists, tool-and-die makers, and maintenance technicians in production and repair environments.

Type B tool holder bushings are commonly used in drilling jigs and modular fixturing systems where a headed, press-fit style bushing is required. They are suited for applications demanding close-tolerance hole guidance in both light and heavy production settings. The headed design prevents the bushing from being pushed through the plate during tool entry and is a standard configuration in jig-bushing work across metal fabrication and general machining operations.

Key Features

• Type B headed design provides a positive stop against the jig plate surface
• Inside diameter of 0.375 inches (0.3750 inches decimal) for standard drill and reamer guidance
• Outside diameter of 1.0000 inches for consistent press-fit or slip-fit installation
• Head thickness of 0.265 inches adds rigidity and prevents bushing migration under load
• Length under head of 1.75 inches accommodates moderate plate thickness and tool travel

Compatibility

Designed as an OEM-style replacement or direct-fit component for standard Type B rotary tool holder bushing applications in drill jigs and machining fixtures.

Installation Notes

Installation is typically performed by a machinist or tooling technician. Ensure the receiving bore in the jig plate is machined to the correct tolerance for the intended fit class before pressing or inserting the bushing. De-energize any associated machine tool and secure the workpiece before performing bushing installation or replacement. Follow applicable shop safety procedures and consult fixture design standards for correct press-fit tolerances.
