Boneham H2622GM Press Fit Headed Drill Bushing

Product Description

The BONEHAM H2622GM is a Type H press fit headed drill bushing designed to guide cutting tools with precision in jig and fixture applications. It features an inside diameter of 0.213 inches with a tight tolerance of +0.0001 to +0.0004 inches, ensuring consistent hole location and repeatability. The body outside diameter is 13/32 inches, and the length under the head measures 1-3/8 inches. Constructed from steel hardened to 60 to 65 HRC, this bushing resists wear under repeated drilling cycles. It is installed by machinists and toolmakers and meets ANSI standards for drill bushing interchangeability.

This bushing is suited for use in drill jigs and fixtures where a permanent, non-renewable guide bushing is required. The headed design seats against the jig plate surface, providing a positive stop during installation. The counterbored configuration accommodates recessed mounting arrangements. It is commonly used in production machining environments, toolrooms, and precision fabrication settings where accurate hole placement is critical across multiple workpieces.

Key Features

• Press fit installation — no locking collar or liner bushing required
• Inside diameter tolerance of +0.0001 to +0.0004 inches for precise tool guidance
• Steel construction hardened to 60 to 65 HRC for extended wear life
• Headed (Type H) design provides a positive seating surface against the jig plate
• Counterbored head allows flush or recessed mounting configurations
• Meets ANSI drill bushing standards for dimensional interchangeability

Compatibility

Designed as an ANSI-standard Type H press fit headed drill bushing for use in drill jigs and fixtures requiring a permanent, non-renewable bushing of 0.213 inches inside diameter.

Installation Notes

Press fit bushings are installed by toolmakers or machinists using an arbor press — never drive in with a hammer, as this can damage the bushing bore or distort the jig plate. The receiving hole in the jig plate must be machined to the appropriate press fit tolerance before installation. Once pressed in, this bushing is not intended for field removal or replacement. Ensure the jig plate and workpiece are secured before beginning any drilling operation.
