Boneham AM00000241 Drill Bushing Hm 6.8 Inch Id Steel

Product Description

The BONEHAM AM00000241 is a press fit headless drill bushing manufactured to HM industry code standards. It is designed to guide drill bits, reamers, and other cutting tools with precision during machining and fabrication operations. The bushing features a 6.8-inch inside diameter, a body outside diameter of 12.00 millimeters, and an overall length of 20.00 millimeters. Constructed from steel, this headless style bushing installs flush into a jig plate without a flange, making it well suited for applications where a smooth, unobstructed working surface is required. Machinists, tool and die makers, and precision fabricators rely on this type of component for repeatable hole location accuracy in production jig and fixture assemblies.

This bushing is used in drill jig fixtures across light manufacturing, metalworking shops, and precision machining environments. The press fit installation method means the bushing is driven or pressed directly into a prepared hole in the jig plate, where it remains fixed during drilling operations. It is appropriate for both production runs and low-volume fabrication work where consistent hole placement is critical. The non-renewable design means the bushing is installed as a permanent fixture component and is not intended to be removed and replaced during service.

Key Features

• HM industry code classification for standardized interchangeability in drill jig applications
• Press fit installation for secure, permanent seating in jig plates
• 6.8-inch inside diameter guides tooling with close dimensional accuracy
• Steel construction provides wear resistance and durability under repeated drilling cycles
• Headless design allows flush mounting where a flange would interfere with the workpiece or fixture
• Non-renewable configuration suited for permanent fixture installations

Compatibility

Designed as an OEM-style replacement or new-installation drill bushing for use in press fit drill jig fixtures requiring an HM-coded headless bushing with a 6.8-inch inside diameter.

Installation Notes

Installation is typically performed by a machinist or tool and die maker using an arbor press or hydraulic press to drive the bushing into a precision-reamed hole in the jig plate. The receiving hole must be machined to the correct interference fit tolerance before installation to ensure proper retention. Power down all associated machinery before fitting or removing jig components. Do not hammer the bushing directly without a proper driver to avoid distorting the bore or damaging the seating surface.
