Boneham AM00000431 Press Fit Headless Drill Bushing Pm

Product Description

The BONEHAM AM00000431 is a press fit headless drill bushing designed to guide drill bits with precision in jig and fixture applications. Classified under industry code PM, this bushing is manufactured from steel for durability under repeated drilling cycles. It features an inside diameter of 13.5 inches, a body outside diameter of 22.00 millimeters, and an overall bushing length of 28.00 millimeters. The headless design allows flush seating in the jig plate without a flange protruding above the surface. Machinists, tool and die makers, and production drilling crews install this type of bushing as a fixed, non-renewable guide in hardened drill jigs.

This bushing is suited for production environments where a permanent, press-fit installation is preferred over a renewable slip-fit arrangement. It is commonly used in flat jig plates for repetitive hole-location drilling in metal fabrication, aerospace component work, and general machining operations. The press fit installation makes it appropriate for high-cycle applications where bushing movement or rotation must be eliminated. It ships as a single unit, making it practical for prototype fixtures as well as production tooling builds.

Key Features

• Press fit installation method for permanent, non-rotating seating in jig plates
• PM industry bushing code for standardized fitment and interchangeability
• Steel construction for wear resistance during high-cycle drilling operations
• Headless design allows flush mounting without a flange above the jig surface
• Non-renewable design suited for fixed, long-term jig installations
• Inside diameter of 13.5 inches for precise drill bit guidance

Compatibility

Designed as an OEM-style replacement and standard fitment press fit headless drill bushing for jig and fixture tooling plates requiring a PM-code, non-renewable bushing.

Installation Notes

Press fit headless drill bushings are installed by machinists and tool and die technicians using an arbor press or hydraulic press to seat the bushing flush with the jig plate surface. Ensure the jig plate bore is machined to the correct interference fit tolerance before pressing to avoid bushing damage or improper seating. Do not use a hammer directly on the bushing bore face. Verify all workholding fixtures are fully secured and equipment is at rest before installation.
