Boneham CB00001344 Press Fit Headed Drill Bushing

Product Description

The BONEHAM CB00001344 is a Type H press fit headed drill bushing designed to guide cutting tools with precision in jig and fixture applications. Manufactured from steel, this bushing features a 0.111 inch inside diameter and a 0.25 inch body outside diameter. It is pressed directly into a drill jig plate and remains fixed in place during service, making it a permanent-style bushing suitable for high-volume or repetitive drilling operations. The headed design provides a positive stop against the jig surface, ensuring consistent tool depth and alignment across production runs.

This bushing is suited for use in machine shops, fabrication environments, and toolroom applications where accurate hole location is critical. It is installed in drill jigs used for metalworking operations including drilling, reaming, and similar guided-tool processes. Its steel construction and press fit design make it appropriate for production fixtures where the bushing is not intended to be replaced in service.

Installation Notes

Installation is performed by machinists or toolmakers using a press to seat the bushing into a correctly sized hole in the jig plate. The mating hole in the jig plate must be machined to the appropriate tolerance to achieve a proper interference fit. Do not hammer the bushing in without proper support, as this can damage the head or distort the bore. Ensure the jig plate and bushing are clean and free of burrs before pressing.
