Boneham AM00000347 Drill Bushing Hm 9.8 Inch Id

Product Description

The BONEHAM AM00000347 is a press fit headless drill bushing manufactured from steel and classified under industry code HM. It is designed to guide cutting tools during drilling operations, maintaining precise hole location and alignment in jig and fixture applications. With an inside diameter of 9.8 inches and a body outside diameter of 15.00 mm, this bushing is pressed directly into a drill jig plate without the use of a flange or locking collar. Machinists, tool-and-die makers, and production fixture builders install this type of bushing where a flush, low-profile installation is required and the bushing is intended to remain fixed in the jig body.

This bushing is suited for use in drilling jigs, fixture plates, and precision guide assemblies in industrial machining environments. The headless press fit design makes it appropriate for applications where a smooth top surface is necessary or where a flanged bushing would interfere with workpiece clearance. It is commonly installed in production and toolroom settings where consistent hole accuracy across repeated drilling cycles is critical.

Key Features

• Press fit installation — no flange or locking collar required for secure seating
• HM industry classification for standard headless drill bushing identification
• Steel construction for durability and wear resistance in repetitive drilling operations
• Inside diameter of 9.8 inches for precise tool guidance
• Non-renewable design — intended as a permanently seated bushing in the jig body
• Overall bushing length of 12.00 mm keeps the profile compact for close-clearance fixtures

Compatibility

Designed as a direct-fit replacement or new-installation headless drill bushing for steel drill jig plates and fixture bodies requiring an HM-type press fit bushing with a 9.8-inch inside diameter.

Installation Notes

Press fit bushings are typically installed by toolmakers or machinists using an arbor press or hydraulic press. The jig plate bore must be machined to the appropriate tolerance for an interference fit before installation. Do not hammer the bushing in freehand, as this can cause misalignment or damage to the bore. Removal of a permanently pressed bushing generally requires pressing or drilling out and replacing the bushing along with the surrounding jig material.
