Boneham AM00000085 Drill Bushing Hm 2.8 Inches Id

Product Description

The BONEHAM AM00000085 is a press fit headless drill bushing with an HM industry code designation, designed to guide drill bits and cutting tools with precision in jig and fixture applications. Made from steel, this bushing installs without a head flange, sitting flush within the drill jig plate for a clean, low-profile fit. The inside diameter measures 2.8 inches, with a body outside diameter of 6.00 millimeters and an overall length of 8.00 millimeters. It is a non-renewable type, meaning it is pressed permanently into the jig plate rather than designed for repeated removal and replacement. Machinists and toolmakers install this type of bushing during jig fabrication or repair.

This drill bushing is suited for production drilling operations where a permanent, headless guide is preferred. It fits into drill jig plates in both job shop and production manufacturing environments. The HM code indicates a standardized size classification used across the tooling industry to match bushings to compatible jig components. Applications include repetitive hole location drilling in metal fabrication, aerospace, and general machining setups where dimensional consistency across multiple workpieces is required.

Key Features

• Press fit installation method for permanent, secure seating in jig plate
• Headless design provides flush, low-profile mounting
• HM industry code for standardized sizing and cross-reference
• Inside diameter of 2.8 inches for accurate tool guidance
• Steel construction for durability in repetitive drilling operations
• Non-renewable type — designed for permanent installation

Compatibility

Designed as an OEM-style replacement or new-installation drill bushing for jig plates and fixtures requiring an HM-coded, press fit headless bushing with a 2.8 inch inside diameter.

Installation Notes

Installation is performed by machinists or toolmakers using a press or arbor press to seat the bushing flush into a properly sized jig plate bore. The mating bore in the jig plate must be machined to the correct interference fit tolerance before installation. Do not drive the bushing in with impact tools, as this can damage the bushing bore or distort the jig plate. Once pressed in, this bushing is not intended for removal and reuse.
