Boneham H1312BF Press Fit Headed Drill Bushing

Product Description

The BONEHAM H1312BF is a Type H press fit headed drill bushing designed to guide cutting tools with precision in jig and fixture applications. It features a 3/64 inch inside diameter and a 13/64 inch body outside diameter, with a 3/4 inch length under the head. Manufactured from steel hardened to 60-65 HRC, this bushing delivers the wear resistance and dimensional stability required for repetitive drilling, reaming, and similar operations. The counterbored head design seats flush or into a recessed pocket, securing the bushing permanently in the jig plate without a locking collar. Installation is by press fit, eliminating the need for additional retention hardware.

This bushing is suited for use in production drilling jigs, tooling fixtures, and machine shop setups where consistent hole location is critical across high-cycle runs. The headed design provides a positive shoulder stop that controls insertion depth and prevents the bushing from pushing through the jig plate under cutting thrust. It is commonly installed by machinists, toolmakers, and fixture builders working to ANSI standards in manufacturing and metalworking environments.

Key Features

• Type H press fit design installs permanently without a locking collar
• 3/64 inch ID with tolerance of +0.0001 to +0.0004 inches for precise tool guidance
• Steel construction hardened to 60-65 HRC for extended wear life
• Counterbored head seats into jig plate for flush or recessed mounting
• Conforms to ANSI standards for drill bushing dimensions and tolerances
• Head outside diameter of 19/64 inch, head height of 3/32 inch

Compatibility

Designed as an OEM-style replacement or new-installation press fit headed drill bushing for standard ANSI-compliant drilling jigs and tooling fixtures requiring a Type H bushing with 3/64 inch ID.

Installation Notes

Press fit bushings are installed by a toolmaker or machinist using an arbor press to drive the bushing squarely into a prepared hole in the jig plate. The jig plate hole must be machined to the correct interference fit tolerance before installation. Once pressed in, this bushing is not intended to be removed or replaced. Verify jig plate material and thickness are adequate to support the press fit retention force before installation.
