Boneham AM00000335 Drill Bushing Hm 9.5 Inch Id

Product Description

The BONEHAM AM00000335 is a press fit headless drill bushing manufactured to HM industry code standards. It is used to guide drill bits with precision during machining and fabrication operations, providing a hardened steel bore that resists wear and maintains accurate hole location over repeated use. The bushing features a 9.5-inch inside diameter and a body outside diameter of approximately 0.591 inches (15.00 mm), with an overall length of approximately 0.472 inches (12.00 mm). It is installed without a head flange, seating flush into the jig plate for applications where a low-profile installation is required. Machinists, toolmakers, and fabrication professionals install this bushing using press-fit tooling in drill jig assemblies.

This bushing is suited for use in drill jigs and fixture plates across general metalworking, tooling, and production machining environments. It is a non-renewable type, meaning it is pressed permanently into the jig plate and is not designed for removal and replacement during normal service. The HM industry code designation indicates a specific combination of inside diameter, outside diameter, and length that conforms to standard drill bushing classifications, allowing it to be sourced as a direct replacement within tooling programs that specify HM-series bushings.

Key Features

• Press fit installation for secure, permanent seating in drill jig plates
• HM industry code classification for standardized dimensional interchangeability
• 9.5-inch inside diameter for precise drill bit guidance
• Steel construction for durability and wear resistance in production environments
• Headless design provides flush, low-profile fit in jig fixtures
• Non-renewable bushing — designed for permanent installation

Compatibility

Designed as an OEM-style replacement or new-installation drill bushing for drill jig fixtures requiring an HM-series press fit headless bushing with a 9.5-inch inside diameter.

Installation Notes

Installation is performed by toolmakers or machinists using an arbor press or hydraulic press to seat the bushing into a properly reamed jig plate bore. The mating bore in the jig plate must be machined to the correct press fit tolerance for the body outside diameter before installation. Do not hammer the bushing in directly without a driver to avoid damage to the bore or bushing. Once pressed in, this bushing is not intended to be removed or reused.
