Boneham AM00000186 Drill Bushing Hm 5.3 in Id

Product Description

The BONEHAM AM00000186 is a press fit headless drill bushing manufactured to HM industry standards. It is designed to guide drill bits accurately during precision hole-making operations in metalworking and machining applications. The bushing features a 5.3-inch inside diameter and a steel construction, providing the rigidity and wear resistance required for consistent, repeatable drilling. It is installed without a head or locking collar, seating flush or below the jig plate surface. Machinists, tool and die makers, and production shop technicians are the typical installers of this component.

This bushing is suited for use in drill jigs and fixture plates where controlled hole location is critical. The headless press fit design makes it appropriate for applications where a flush or recessed bushing is required and the bushing will remain fixed in the jig body for the production run. It is commonly found in precision manufacturing environments, machine shops, and metal fabrication facilities where repeatable positional accuracy is a production requirement.

Key Features

• HM industry standard bushing code for straightforward cross-reference and replacement
• Press fit installation method — no set screw or retaining ring required
• Headless design allows flush or sub-flush seating in jig plates
• Steel construction provides hardness and wear resistance for sustained drilling operations
• Non-renewable design — intended as a permanent press-fit installation in the jig body

Compatibility

Designed as an OEM-style replacement or new-installation drill bushing for standard HM-series drill jig fixtures in precision metalworking and machining setups.

Installation Notes

Press fit bushings are typically installed by a machinist or toolmaker using an arbor press or hydraulic press to achieve proper interference fit in the jig plate bore. The mating bore in the jig plate must be machined to the correct tolerance to achieve the required press fit; verify bore diameter against the bushing outside diameter specification before installation. Do not hammer the bushing in without a press tool, as this can damage the bushing OD or distort the jig plate bore. Once pressed in, the bushing is not intended to be removed and reinstalled.
