Boneham AM00000342 Drill Bushing Hm 9.75 in Id

Product Description

The BONEHAM AM00000342 is a press fit headless drill bushing in the HM industry series, designed to guide drill bits and cutting tools with precision during machining and metalworking operations. This bushing features a 9.75-inch inside diameter and a steel body construction, making it a durable choice for high-repetition drilling applications. It installs without a head flange, seating flush within a jig plate or fixture body for applications where a low-profile installation is required. Machinists, toolmakers, and manufacturing technicians install this bushing type in drill jigs, fixtures, and production tooling setups where consistent hole location is critical.

This bushing is suited for use in metal fabrication, production machining, and tooling environments where press fit installation provides a secure, non-removable bushing seat. It is appropriate for both light production and heavy-duty fixture applications requiring precise drill guidance. The HM industry code designates its dimensional standard, allowing it to serve as a direct dimensional replacement within HM-series tooling setups. It is installed by pressing directly into a prepared hole in the jig body without additional hardware.

Key Features

• Press fit installation method for a permanent, secure seat in jig plates and fixtures
• HM industry code designation for standardized dimensional compatibility
• 9.75-inch inside diameter for large-bore drill guidance applications
• Steel body construction for wear resistance and long service life
• Headless design allows flush, low-profile installation within fixture bodies
• Non-renewable bushing intended for permanent installation

Compatibility

Designed as an OEM-style replacement or direct-fit option for HM-series press fit headless drill bushing applications in standard drill jig and fixture tooling setups.

Installation Notes

Installation is performed by toolmakers or machining professionals using an arbor press or hydraulic press to seat the bushing flush into a precisely reamed jig plate hole. The receiving hole must be machined to the correct interference fit tolerance for the bushing outside diameter before installation. Power down all associated machinery before performing bushing installation or removal. Once pressed in, this bushing is not designed for removal and reinstallation.
