Boneham AM00000027 Press Fit Headless Drill Bushing Hm

Product Description

The BONEHAM AM00000027 is a press fit headless drill bushing classified under industry code HM. It is designed to guide drill bits with precision during machining operations, reducing tool wander and improving hole accuracy. The bushing is manufactured from steel, providing durability under repeated use in production and maintenance environments. With an inside diameter of 12.5 inches, a body outside diameter of 22.00 millimeters, and an overall bushing length of 16.00 millimeters, this part is sized for specific jig plate applications. It is a non-renewable bushing, meaning it is intended as a permanent press-in installation rather than a slip-in replacement style.

This drill bushing is used in machine shop, tooling, and manufacturing environments where accurate hole guidance is required. It is well suited for drill jigs in both production and repair settings. The press fit installation method means the bushing is driven or pressed directly into the jig plate bore without a locking mechanism, making it appropriate for fixed, dedicated-use tooling setups. Machinists and toolmakers working with steel jig plates will find this bushing compatible with standard HM-series tooling applications.

Key Features

• HM industry code classification for standard drill bushing compatibility
• Press fit installation method for permanent, fixed positioning in jig plates
• Steel construction for durability and resistance to wear under repeated drilling cycles
• Non-renewable design suited for dedicated single-operation tooling fixtures
• Inside diameter of 12.5 inches for precise drill bit guidance
• Compact body with 22.00 millimeter outside diameter and 16.00 millimeter overall length

Compatibility

Designed as an OEM-style press fit headless drill bushing for use in HM-series drill jig applications requiring a permanent bushing installation.

Installation Notes

Installation of press fit drill bushings is typically performed by machinists or toolmakers using an arbor press or hydraulic press to seat the bushing flush and square within the jig plate bore. The jig plate bore should be verified to the correct tolerance before pressing to avoid damage to the bushing or plate. Do not drive the bushing with an impact tool or strike it directly with a hammer without a proper seating fixture. Always verify the inside diameter clearance against the intended drill bit size before finalizing the tooling setup.
