Boneham AM00000218 Drill Bushing Hm 6.2 Inches Id

Product Description

The BONEHAM AM00000218 is a headless drill bushing designed for press fit installation in drill jig applications. Manufactured from steel, this HM-series bushing provides a precise guide bore for drill bits and other cutting tools, maintaining accurate hole location across repeated operations. The inside diameter measures 6.2 inches, with a body outside diameter of approximately 0.472 inches (12.00 mm) and an overall length of approximately 0.394 inches (10.00 mm). It is a non-renewable design, meaning it is permanently pressed into the jig plate rather than being removable for replacement during production runs. Machinists and toolmakers rely on this type of bushing to maintain consistent drill alignment in metal fabrication and precision machining environments.

This bushing is suited for use in drill jig fixtures across a range of machining operations including drilling, reaming, and similar guided-tool processes. It is appropriate for production and toolroom applications where a permanent, flush-mount bushing is required. The headless profile sits flush with or below the surface of the jig plate, making it suitable for close-tolerance fixtures where a flanged bushing would interfere with workpiece positioning or clamping.

Key Features

• Press fit installation for permanent, rigid seating in drill jig plates
• HM industry bushing code for standardized sizing and interchangeability
• 6.2-inch inside diameter for precise drill guidance
• Headless design sits flush with jig plate surface
• Steel construction for durability in repeated-cycle machining use
• Non-renewable design eliminates liner bushing requirement

Compatibility

Designed as an OEM-style replacement or new-build component for standard drill jig fixtures requiring a press fit headless bushing in the HM series.

Installation Notes

Installation is performed by a machinist or toolmaker using a press or arbor press to seat the bushing flush into a properly sized jig plate bore. The receiving bore must be machined to the correct interference-fit tolerance for the bushing outside diameter before installation. Once pressed in, this bushing is not intended for removal or reuse. Ensure the jig plate is secured and the bushing is driven in squarely to prevent bore damage or misalignment.
