Boneham H208FV Press Fit Headed Drill Bushing

Product Description

The BONEHAM H208FV is a Type H press fit headed drill bushing designed to guide drill bits and cutting tools with precision in jig and fixture applications. Manufactured from steel with a hardness rating of 60 to 65 HRC, this bushing delivers consistent bore alignment and long service life under repeated drilling cycles. The inside diameter measures 0.191 inches and the body outside diameter measures 5/16 inches, with a length under head of 1/2 inch. It is installed by pressing directly into a pre-bored jig plate without the need for locking mechanisms, making setup fast and repeatable for production environments.

This bushing is suited for use in drill jigs, fixture plates, and tooling setups found in machine shops, fabrication facilities, and manufacturing operations. It is appropriate for both one-time production runs and moderate-volume applications where a non-renewable press fit design meets the required accuracy and durability. Machinists, toolmakers, and fixture builders are the primary installers of this component.

Key Features

• Press fit installation method for fast, tool-free seating in jig plates
• Type H headed design with a head outside diameter of 27/64 inches and head height of 1/8 inch
• Steel construction hardened to 60 to 65 HRC for wear resistance
• Inside diameter tolerance of +0.0001 to +0.0004 inches for precise drill guidance
• Meets ANSI standards for drill bushing geometry and fitment
• Non-renewable (fixed) design — no liner bushing required

Compatibility

Designed as a direct-fit replacement or new-installation press fit headed drill bushing for standard jig plates and fixture tooling that accept a 5/16 inch body outside diameter, Type H bushing per ANSI specifications.

Installation Notes

Press fit bushings are installed by a toolmaker or machinist using an arbor press into a precision-bored hole in the jig plate. The receiving bore must be machined to the correct tolerance to achieve the required interference fit — consult ANSI bushing press fit tables before boring. Once installed, these bushings are not intended for removal and replacement; plan jig plate design accordingly. Always verify that the bushing ID matches the drill or reamer being guided before pressing into the plate.
