Boneham AM00000348 Drill Bushing Hm 9.8 in Id Steel

Product Description

The BONEHAM AM00000348 is a press fit headless drill bushing in the HM industry code series, manufactured from steel for use in precision drilling and machining operations. With an inside diameter of 9.8 inches, a body outside diameter of 15.00 millimeters, and an overall length of 20.00 millimeters, this bushing guides drill bits and boring tools to maintain accurate hole location and alignment. It installs permanently into a drill jig plate without a head flange, keeping the bushing flush with the jig surface. Machinists, tool and die makers, and production drilling technicians are the primary installers of this type of component.

This bushing is suited for drill jig applications in metalworking and manufacturing environments where consistent, repeatable hole placement is required. The headless design is appropriate for applications where a protruding flange would interfere with workpiece seating or jig clearance. The press fit installation method locks the bushing in place without mechanical fasteners, making it a reliable fixed-liner option for production runs and quality-controlled drilling setups.

Key Features

• HM industry code series press fit headless design for permanent jig installation
• Inside diameter of 9.8 inches for precise drill bit or tool guidance
• Body outside diameter of 15.00 millimeters for controlled press fit retention
• Overall bushing length of 20.00 millimeters to support adequate tool guidance depth
• Steel construction for durability in production drilling environments
• Non-renewable fixed bushing — designed for long-term single-position use

Compatibility

Designed as an OEM-style fixed liner for steel drill jig plates requiring HM series press fit headless bushings with a 9.8-inch inside diameter.

Installation Notes

Press fit bushings should be installed by a qualified machinist or toolmaker using an arbor press or hydraulic press to seat the bushing squarely and fully into the prepared jig plate bore. The receiving bore must be machined to the appropriate tolerance for an interference fit to ensure the bushing does not rotate or back out during service. Do not hammer the bushing in freehand, as this can damage the bushing bore or distort the outer diameter. Once pressed in, this bushing is not intended to be removed and reinstalled.
