Boneham AM00000022 Hm Press Fit Headless Drill Bushing 11in Id

Product Description

The BONEHAM AM00000022 is a press fit headless drill bushing manufactured to HM industry standards. It is used to guide drill bits and other cutting tools with precision in jig and fixture applications. The bushing installs without a head or flange, seating flush within a drilled or reamed hole in the jig body. Machined from steel, it provides a hard, wear-resistant bore surface that maintains accurate hole location during repetitive drilling operations. Key dimensions include an 11-inch inside diameter and an 18.00 mm body outside diameter with a 12.00 mm overall length. It is a permanent, non-renewable installation.

This bushing is suited for industrial tooling, jig plate construction, and production machining environments where consistent hole placement is required across high-cycle operations. It is appropriate for use in both light and heavy manufacturing settings where a headless, press-in style bushing is specified by the tooling design. Each unit is sold individually and is packaged as a single piece. Machinists, toolmakers, and fixture builders are the primary installers in shop or toolroom environments.

Key Features

• HM industry bushing code for standardized interchangeability
• Press fit installation method for permanent, flush-mount seating
• 11-inch inside diameter for precise tool guidance
• Steel construction provides hardness and wear resistance at the bore surface
• Non-renewable design for fixed, long-term jig installations
• Headless profile eliminates flange interference with workpiece surfaces

Compatibility

Designed as an OEM-style replacement or new-installation bushing for jigs and fixtures requiring an HM-code press fit headless drill bushing with an 11-inch inside diameter.

Installation Notes

Press fit bushings are typically installed by toolmakers using an arbor press or hydraulic press to achieve the required interference fit. The receiving hole in the jig plate must be precision-reamed to the correct tolerance for the bushing outside diameter before installation. Never drive the bushing in with an impact tool, as this can damage the bore geometry. Once pressed in, the bushing is considered permanent and is not intended for removal and replacement.
