Boneham AM00000356 Press Fit Headless Drill Bushing Hm

Product Description

The BONEHAM AM00000356 is a press fit headless drill bushing manufactured to HM industry standards. It is designed to guide drill bits and other cutting tools with precision in jig and fixture applications. Made from steel, this bushing is pressed directly into a drill jig plate without a head flange, keeping the top surface flush. The inside diameter designation is M and the body outside diameter is 18 mm. The overall bushing length is 20 mm. Machinists, toolmakers, and fixture builders rely on this type of bushing to maintain accurate hole location and extend tool life in production drilling operations.

This bushing is suited for use in drill jigs and production fixtures where a flush, headless installation is required. The press fit design holds the bushing securely in the jig plate without additional fasteners, making it a clean solution for tight-tolerance applications. It is commonly installed in metalworking shops, machine shops, and manufacturing facilities handling repetitive drilling, reaming, or boring operations. The non-renewable design means it is intended as a permanent installation once pressed in.

Compatibility

Designed as an OEM-style replacement or direct-fit option for HM-type press fit headless drill jig bushings with an M inside diameter designation and an 18 mm outside diameter.

Installation Notes

Press fit drill bushings are typically installed by toolmakers or machinist trades using an arbor press or hydraulic press. The jig plate bore must be machined to the correct interference fit tolerance before installation to ensure proper retention. Do not hammer the bushing in without a press and driver to avoid damage to the bushing or jig plate. Once pressed in, this non-renewable bushing is not designed for removal and reinstallation.
