Value Collection SC84949767 Tool Holder Bushing Type B

Product Description

The VALUE COLLECTION SC84949767 is a Type B rotary tool holder bushing designed to locate and support cutting tools, drill bits, and boring bars within tool holders and jig boring fixtures. With a 1-inch inside diameter and a 1.25-inch outside diameter, this bushing provides a precise bore interface that reduces runout and maintains accurate tool positioning during machining operations. The head thickness measures 0.265 inches and the length under head is 2.125 inches. Machinists and toolroom technicians install this bushing to extend tool holder life and maintain consistent hole location in production and job-shop environments.

This Type B tool holder bushing is suited for use in drill jigs, rotary tool holders, and boring fixtures found in machine shop settings, both in small-batch job shops and higher-volume production lines. The 1-inch bore accommodates common shank diameters in that size range, making it a practical replacement or spare for standard tooling setups. Installation is typically performed by machinists or toolroom personnel during fixture setup or tool holder maintenance.

Compatibility

Designed as an OEM-style replacement or spare for Type B rotary tool holder bushings with a 1-inch bore, suitable for use in standard drill jig and rotary tool holder applications that accept this bushing geometry.

Installation Notes

Installation is performed by qualified machinists or toolroom technicians. Always power down and lock out the machine spindle before removing or seating a tool holder bushing. Press or hand-seat the bushing squarely into the holder bore to avoid cocking or galling the fit surfaces. Verify bore cleanliness and check for burrs on both the bushing OD and the holder bore before installation to maintain dimensional accuracy.
