Boneham H2022FH Press Fit Headed Drill Bushing

Product Description

The BONEHAM H2022FH 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 0.173 inches (wire gauge #17) with a tight tolerance of +0.0001 to +0.0004 inches, ensuring consistent hole placement across repeated drilling operations. The body outside diameter is 5/16 inches, the head outside diameter is 27/64 inches, and the head height is 1/8 inches. Hardened to 60-65 HRC, this bushing maintains accuracy under sustained production use. Machinists, toolmakers, and fixture builders install this component in drill jigs to control tool alignment and protect the workpiece.

This bushing is suited for production environments where a headed, press fit bushing is required in a counterbored jig plate. The 1-3/8 inch length under head accommodates moderate plate thickness and provides stable tool guidance through the full cutting depth. The head seats flush against the jig plate surface when installed in a counterbored hole, preventing axial movement during use. It is appropriate for both manual drilling and machine-fed drill press operations in metalworking, fabrication, and toolroom settings.

Key Features

• Press fit installation method for permanent, non-renewable jig bushing applications
• Inside diameter tolerance of +0.0001 to +0.0004 inches for precise tool guidance
• Hardness of 60 to 65 HRC for long service life in repetitive drilling operations
• Counterbored head design seats flush in the jig plate surface
• Meets ANSI standards for drill bushing dimensions and tolerances
• Steel construction for durability in metalworking and fabrication environments

Compatibility

Designed as an ANSI-standard Type H press fit headed drill bushing for use in counterbored drill jig plates requiring a permanent, non-renewable bushing with a 0.173 inch bore and 5/16 inch body diameter.

Installation Notes

Installation is performed by a toolmaker or machinist using an arbor press or hydraulic press to seat the bushing into a precision-reamed counterbored hole in the jig plate. The jig plate bore must be machined to the appropriate press fit tolerance before installation. Once pressed in, this bushing is not intended for removal or replacement. Verify inside diameter clearance with the drill or reamer shank before pressing the bushing into the fixture.
