Boneham CB00001352 Press Fit Headed Drill Bushing

Product Description

The BONEHAM CB00001352 is a Type H press fit headed drill bushing designed to guide cutting tools with precision in jig and fixture applications. It features a 0.104 inches inside diameter (Wire Size #37) and a 1/4 inches body outside diameter, with a 1/2 inches length under the head. Constructed from steel hardened to 60-65 HRC, this bushing delivers consistent hole placement accuracy under repeated drilling cycles. The headed design provides a positive stop against the jig plate surface. Machinists, toolmakers, and fixture builders install this component in production drilling setups where repeatable positional accuracy is required.

This bushing is suited for use in drill jigs and machining fixtures in metalworking environments, both light manufacturing and production-floor settings. The press fit installation method locks the bushing permanently into the jig body without additional hardware. It conforms to ANSI standards for drill bushing geometry and tolerancing, making it a direct fit in jigs designed to those specifications. The inside diameter tolerance of +0.0001 to +0.0004 inches supports close-tolerance drilling operations where drill wander must be minimized.

Key Features

• Type H headed press fit design provides a positive stop flush against the jig plate
• 0.104 inches ID (Wire Size #37) with tolerance of +0.0001 to +0.0004 inches for close-tolerance drilling
• Steel construction hardened to 60-65 HRC for extended wear life in production use
• 1/2 inches length under head guides drill through thicker jig plates
• 23/64 inches head outside diameter and 3/32 inches head height per ANSI standards
• Non-renewable press fit design for permanent installation in fixed jig bodies

Compatibility

Designed as an ANSI-standard press fit headed drill bushing for use in drill jigs and fixtures requiring a Type H bushing with a 1/4 inches body outside diameter and 0.104 inches inside diameter.

Installation Notes

Press fit headed drill bushings are installed by toolmakers and fixture builders using an arbor press or similar controlled pressing equipment. The jig plate bore must be machined to the appropriate interference fit tolerance before installation. Once pressed in, the bushing is not intended for removal or reuse. Always verify bore size and finish in the jig plate before pressing to avoid bushing damage or misalignment.
