Boneham AM00000295 Drill Bushing Hm 8.3 Inches Id

Product Description

The BONEHAM AM00000295 is a press fit headless drill bushing manufactured to industry code HM and designed to guide drill bits with precision during machining operations. Made from steel, this bushing installs permanently into a jig plate without a head or flange, keeping the working surface flush. It accepts tooling with an inside diameter of 8.3 inches and features a body outside diameter of 15.00 millimeters and an overall length of 25.00 millimeters. Machinists, tool and die makers, and jig builders use this bushing in production drilling applications where consistent hole location and repeatable accuracy are required across multiple workpieces.

This press fit headless drill bushing is suited for use in drill jig fixtures in both production and toolroom environments. The HM industry code designates a specific standardized size series, making it a recognized fitment in jig and fixture assemblies that call for headless press fit bushings. It is non-renewable, meaning it is intended for permanent installation rather than field replacement during a production run. Applications include metalworking, fabrication, and general machining where a fixed, flush-mount drill guide is preferred.

Key Features

• Press fit installation method for permanent, flush-mount placement in jig plates
• Headless design keeps the jig surface unobstructed during drilling
• HM industry code for standardized sizing and interchangeability
• Steel construction for durability under repeated tooling contact
• Non-renewable bushing intended for fixed, long-term jig use

Compatibility

Designed as an OEM-style replacement or new-build component for drill jig fixtures requiring a press fit headless bushing in the HM size series.

Installation Notes

Press fit bushings are typically installed by a machinist or tool and die maker using an arbor press or hydraulic press to seat the bushing flush with the jig plate surface. The receiving hole in the jig plate must be machined to the correct press fit tolerance for the bushing outside diameter before installation. Do not hammer the bushing in with an impact tool, as this can damage the bushing bore or distort the jig plate. Once pressed in, this bushing is not designed for removal or field replacement.
