Boneham CB00001162 Drill Bushing Type H 1/4 in Id 1/2 in Od

Product Description

The BONEHAM CB00001162 is a Type H press fit headed drill bushing machined from hardened steel for use in jig and fixture applications. It features a 0.25 inch inside diameter, a 0.5 inch body outside diameter, and a 39/64 inch head outside diameter, providing a secure press fit installation in drill jig plates. The bushing is hardened to 60 to 65 HRC, delivering the surface durability needed to guide drill bits accurately under repeated use in production and maintenance environments. This is a non-renewable, fixed-position bushing intended for applications where the bushing remains permanently installed in the jig body.

This bushing is suited for metalworking, fabrication, and machining operations where repeatable hole location accuracy is required. It is commonly installed in drill jigs used in job shops, maintenance repair operations, and production floor environments. The Type H designation follows ANSI standards for headed press fit drill bushings, making it a recognized and interchangeable style across standard tooling setups. Machinists and toolmakers select this bushing when a permanent guide is appropriate and bushing replacement is not anticipated during the service life of the jig.

Key Features

• Press fit installation method for permanent, fixed positioning in drill jig plates
• Type H headed configuration per ANSI standards provides positive axial stop during installation
• Hardened steel construction at 60 to 65 HRC resists wear from repeated drill bit contact
• Inside diameter tolerance of +0.0001 to +0.0004 inches ensures precise drill guidance
• Non-renewable design simplifies jig construction where bushing replacement is not required
• Head outside diameter of 39/64 inches seats flush against the jig plate surface

Compatibility

Designed as an ANSI-compliant Type H press fit headed drill bushing for use in standard drill jig plates sized to accept a 0.5 inch body outside diameter bushing.

Installation Notes

Installation is performed by machinists or toolmakers using an arbor press or similar pressing equipment to seat the bushing into a pre-reamed jig plate bore. Power should be removed from any associated machinery before performing jig modifications. Because this is a non-renewable press fit bushing, the jig plate bore must be accurately sized prior to installation to prevent damage to the bushing or plate. Follow applicable shop safety procedures and ANSI tooling guidelines when pressing bushings into hardened or unhardened jig plates.
