Boneham H208FH Headed Drill Bushing 0.173 in Id Steel

Product Description

The BONEHAM H208FH is a press fit headed drill bushing designed to guide cutting tools with precision during drilling, reaming, and boring operations. Manufactured from steel with a hardness rating of 60 to 65 HRC, this Type H bushing delivers the wear resistance required in production jig and fixture applications. The H208FH features an inside diameter of 0.173 inches (Wire Gauge No. 17) with a close tolerance of +0.0001 to +0.0004 inches, ensuring accurate and repeatable hole location. It installs permanently into a jig plate via press fit and is not designed for renewal or removal once seated.

This bushing is suited for use in drill jigs, fixture plates, and tooling setups found in machine shops, fabrication facilities, and production environments. It is appropriate for applications requiring permanent tool guidance with a headed configuration to provide a positive stop against the jig plate surface. The head outside diameter measures 27/64 inches, the head height measures 1/8 inch, and the length under the head is 1/2 inch. The body outside diameter is 5/16 inch. Toolmakers, machinists, and jig-and-fixture builders are the primary installers of this component.

Key Features

• Press fit installation for permanent, non-renewable seating in jig plates
• Inside diameter of 0.173 inches (No. 17 wire gauge) with tolerance of +0.0001 to +0.0004 inches
• Steel construction hardened to 60 to 65 HRC for extended tool-guide wear life
• Headed (Type H) design provides a positive stop flush against the jig plate surface
• Body outside diameter of 5/16 inch with a 27/64 inch head outside diameter
• Conforms to ANSI standards for drill bushing dimensions and tolerances

Compatibility

Designed as a standard ANSI-compliant Type H press fit headed drill bushing for use in drill jig plates and fixture tooling requiring a permanent, non-renewable bushing with a 0.173 inch bore.

Installation Notes

Installation is performed by machinists or toolmakers using an arbor press or hydraulic press to seat the bushing flush into a precision-bored jig plate hole. The mating hole in the jig plate must be machined to the appropriate press fit tolerance to ensure proper retention. Because this is a non-renewable bushing, the plate hole and bushing should be inspected carefully before pressing, as removal will damage the surrounding material. No power sources need to be isolated, but all cutting and pressing equipment should be confirmed in a safe, controlled state before beginning installation.
