Boneham AM00000127 Hm Press Fit Drill Bushing 3.75 in

Product Description

The BONEHAM AM00000127 is a press fit headless drill bushing conforming to the HM industry code, designed for precise drill guidance in machining and tooling applications. Manufactured from steel, this bushing features a 3.75-inch inside diameter and a body outside diameter of 7.00 millimeters with an overall length of 8.00 millimeters. It installs without a head flange, seating flush with the jig plate surface for applications where a low-profile installation is required. This component is installed by machine shops, toolroom technicians, and production machinists who require consistent, repeatable drill positioning in jig and fixture setups.

This drill bushing is suited for use in drill jig plates and fixture bodies where press-fit retention and precise bore guidance are required. It is a non-renewable type, meaning it is pressed permanently into the jig body rather than retained with a lock mechanism. Typical applications include production drilling operations in metalworking environments where maintaining accurate hole location across repeated cycles is critical. The HM industry code designation allows direct cross-referencing with standard tooling catalogs used across the machining trade.

Key Features

• HM industry code designation for standard cross-reference compatibility
• Press fit installation method seats bushing permanently into jig plate
• Headless design provides flush, low-profile seating in the jig body
• Steel construction offers durability for repeated drilling operations
• Non-renewable design — intended for permanent press-in installation
• 3.75-inch inside diameter for precise drill or tool guidance

Compatibility

Designed as an OEM-style replacement or direct-fit component for drill jig plates and fixture assemblies requiring an HM-code press fit headless bushing with a 3.75-inch inside diameter.

Installation Notes

Installation is performed by toolroom or machine shop personnel using an arbor press or hydraulic press to seat the bushing flush into the jig plate bore. Ensure the receiving hole in the jig plate is machined to the correct interference fit tolerance before pressing to avoid bushing damage or bore distortion. Once pressed in, this non-renewable bushing is not designed for removal and reinstallation. Follow applicable shop safety procedures when operating pressing equipment.
