Boneham H266GO Press Fit Headed Drill Bushing 7/32 Id

Product Description

The BONEHAM H266GO is a Type H press fit headed drill bushing manufactured from hardened steel for precision hole-location guidance in drill jigs and fixture applications. With a 7/32 inch inside diameter and a 13/32 inch body outside diameter, this bushing provides a controlled, repeatable drill path for production and toolroom work. The inside diameter is held to a tight tolerance of +0.0001 to +0.0004 inches, ensuring consistent bit alignment across repeated operations. Hardness is rated at 60 to 65 HRC, giving the bushing excellent wear resistance under continuous drilling cycles. Installation is by press fit, requiring no additional locking hardware.

This bushing is suited for use in metal fabrication shops, toolrooms, and manufacturing environments where drill jig accuracy is critical. The headed design provides a positive stop against the jig plate, controlling the installed depth of the bushing. With a 3/8 inch length under the head and a 1/2 inch head outside diameter, it fits standard jig plate thicknesses common in precision machining setups. It is typically installed by toolmakers or fixture builders working to ANSI standards.

Key Features

• Type H press fit installation — no locking ring or liner required
• Inside diameter: 7/32 inch with tolerance of +0.0001 to +0.0004 inches for tight bit guidance
• Hardness: 60 to 65 HRC for high wear resistance in repetitive drilling applications
• Headed design controls installed depth against the jig plate surface
• Meets ANSI standards for drill bushing dimensions and tolerances
• Not renewable — designed as a permanent press fit installation

Compatibility

Designed as a direct-fit replacement or new installation for ANSI Type H press fit headed drill bushing applications requiring a 7/32 inch inside diameter and 13/32 inch body outside diameter.

Installation Notes

Press fit bushings are installed by toolmakers or machinist-trained personnel using an arbor press or hydraulic press — never drive with a hammer, as uneven force will damage the bushing bore or jig plate. Verify the jig plate bore diameter matches the bushing outside diameter tolerance before pressing to avoid galling or undersized fit. Once installed, press fit bushings are considered permanent and are not intended for removal and reuse.
