Value Collection SC90011974 Tool Holder Bushing Type B

Product Description

The VALUE COLLECTION SC90011974 is a Type B rotary tool holder bushing used in drill jigs, fixture plates, and precision machining setups. It features an inside diameter of 0.1875 inches, an outside diameter of 0.7500 inches, and a length under head of 1.5000 inches. The head thickness measures 0.1900 inches. This bushing guides cutting tools, drill bits, and reamers to precise locations during machining operations. It is handled and installed by machinists, tool-and-die makers, and CNC setup technicians working in production or job-shop environments.

This Type B tool holder bushing is suited for use in fixed or renewable bushing systems on drill jigs and production fixtures. It is appropriate for light-to-medium duty drilling, reaming, and boring operations where accurate hole location is required. The compact outside diameter and short-to-medium length under head make it a practical choice for confined fixture layouts or closely spaced hole patterns on machined workpieces.

Key Features

• Type B bushing geometry with a flanged head for positive axial seating
• Inside diameter of 0.1875 inches for 3/16 inch tooling
• Outside diameter of 0.7500 inches for standard jig plate bores
• Length under head of 1.5000 inches for adequate tool guidance depth
• Head thickness of 0.1900 inches provides a positive stop against the fixture surface
• Lightweight at 0.132 pounds, minimizing fixture weight in multi-bushing applications

Compatibility

Designed as an OEM-style replacement or direct fitment bushing for drill jig and fixture applications requiring a Type B configuration with 3/16 inch inside diameter and 3/4 inch outside diameter.

Installation Notes

Installation is performed by machinists or tooling technicians. The mating jig plate bore should be reamed to the appropriate press or slip fit tolerance before installation to ensure accurate bushing location. Deburr and clean the bore and bushing exterior before pressing or seating. Always secure the workpiece and de-energize any associated machine before servicing or replacing tooling bushings.
