Boneham AM00000230 Drill Bushing Hm 6.6 in Id

Product Description

The BONEHAM AM00000230 is a press fit headless drill bushing designed to guide drill bits and cutting tools with precision in production drilling applications. Classified under industry code HM, this bushing features a 6.6-inch inside diameter and is manufactured from steel for durability under repeated tooling cycles. It is headless in profile, meaning it sits flush with the jig plate surface, making it well suited for applications where a protruding flange would interfere with workpiece clamping or fixture clearance. Licensed machinists and tooling specialists install this bushing in drill jigs and fixture plates as part of precision manufacturing setups.

This bushing is used in industrial and production machining environments where consistent hole location accuracy is required. The press fit installation method locks the bushing firmly into the jig plate without additional fasteners, providing a stable guide for high-volume drilling operations. It is non-renewable, meaning it is intended as a permanent press fit installation rather than a slip-in replaceable liner.

Key Features

• HM industry code classification for standard headless press fit drill bushing applications
• 6.6-inch inside diameter provides precise drill guidance
• Steel construction for wear resistance under continuous drilling cycles
• Headless design sits flush with jig plate surface, eliminating flange interference
• Press fit installation method secures the bushing without additional fasteners
• Non-renewable design for permanent fixture integration

Compatibility

Designed as an OEM-style replacement or new-installation drill bushing for steel jig plates and fixture assemblies requiring an HM-classified headless press fit bushing with a 6.6-inch inside diameter.

Installation Notes

Installation is performed by qualified machinists or tooling technicians using a hydraulic or arbor press to seat the bushing flush into a properly toleranced jig plate bore. The receiving bore in the jig plate must be machined to the correct interference fit tolerance for the bushing outside diameter before pressing. Do not hammer the bushing directly without a proper driver to avoid damage to the bore or bushing geometry. Verify bore cleanliness and bushing alignment before applying press force.
