Boneham AM00000300 Drill Bushing Hm 8.5 Inch Id

Product Description

The BONEHAM AM00000300 is a press fit headless drill bushing in the HM industry code series, designed to guide drill bits with precision in production drilling applications. With an inside diameter of 8.5 inches and a body outside diameter of approximately 0.591 inches (15.00 mm), this bushing provides accurate hole location and consistent tool guidance. Constructed from steel, it delivers durability under repeated drilling cycles. The headless design allows flush mounting in jig plates without a protruding flange, making it suited for applications where clearance is limited or where multiple bushings must be closely spaced.

This bushing is used in metal fabrication, machine shops, and production environments where drill jigs are required for repeatable, accurate hole placement. It is installed in jig plates or fixture bodies and is not designed to be renewed or replaced in the field once pressed in. Machinists, tool and die makers, and fixture builders are the typical end users for this type of component.

Key Features

• HM industry code series headless press fit design for flush, flangeless installation
• 8.5 inch inside diameter provides precise drill bit guidance
• Steel construction for strength and wear resistance under repeated use
• Fixed (non-renewable) bushing — permanently pressed into the jig plate
• Overall bushing length of approximately 0.787 inches (20.00 mm)

Compatibility

Designed as an OEM-style replacement or direct-fit component for drill jigs and fixture plates requiring an HM series press fit headless drill bushing with an 8.5 inch inside diameter.

Installation Notes

Press fit bushings are installed by machinists or tool and die makers using an arbor press to achieve proper interference fit into the jig plate bore. Ensure the receiving bore is machined to the correct tolerance before pressing to avoid bushing damage or improper seating. This is a non-renewable bushing and is not intended for removal or reuse once installed. Follow applicable shop safety practices and secure workpieces firmly before pressing.
