Value Collection SC84949734 Tool Holder Bushing Type B

Product Description

The VALUE COLLECTION SC84949734 is a Type B rotary tool holder bushing designed for use in drill jigs and tooling fixtures where precise bore alignment is required. With an inside diameter of 0.625 inches, an outside diameter of 1.25 inches, and a length under head of 2.125 inches, this bushing provides a stable, close-tolerance guide for cutting tools during machining operations. The head thickness measures 0.265 inches, giving it a positive-stop shoulder that seats flush against the jig plate. Machinists, tool and die makers, and CNC setup technicians install this type of component as part of fixed or slip-renewable drill bushing systems.

This Type B tool holder bushing is suited for production drilling, reaming, and boring applications in both job-shop and production machining environments. It fits into jig plates where a headed bushing with a 1.25-inch outside diameter is specified. Typical installations involve press-fitting or slip-fitting the bushing into a liner or directly into a jig body to guide drill bits, reamers, or other rotary cutting tools to a precise location repeatedly across multiple workpieces.

Key Features

• Type B headed bushing profile provides a positive-stop shoulder for consistent seating depth
• Inside diameter of 0.625 inches for guiding standard rotary cutting tools
• Outside diameter of 1.25 inches for compatibility with matching liner or jig bore
• Length under head of 2.125 inches supports deep-hole guidance and extended tool travel
• Head thickness of 0.265 inches adds clamping surface and prevents axial migration during use
• Weighs 1.606 pounds — solid construction for stable, repeatable tool guidance

Compatibility

Designed as an OEM-style replacement or standard tooling component for drill jig assemblies requiring a Type B headed bushing with a 0.625-inch bore and 1.25-inch outside diameter.

Installation Notes

Installation is typically performed by a machinist or tooling technician. Ensure the receiving bore in the jig plate is clean and dimensionally verified before pressing or sliding the bushing into position. Power down and lock out any associated machine before servicing or replacing bushings in a live fixture. Follow applicable ANSI and shop safety standards for press-fit tooling components.
