Boneham AM00000541 Drill Bushing Pm 3.8mm Id Steel

Product Description

The BONEHAM AM00000541 is a press fit headless drill bushing in the PM industry code series, manufactured from hardened steel and designed to guide drill bits with precision in jig and fixture applications. With an inside diameter of 3.8 mm and a body outside diameter of 7.00 mm, this bushing is pressed directly into a drill jig plate without the use of a head flange. The overall bushing length is 12.00 mm. Hardness is rated at 60 to 65 HRC, providing wear resistance under repeated drilling cycles. Inside diameter tolerance is +0.004/+0.012 mm. Machinists, tool and die makers, and production drilling technicians are the primary installers.

This bushing is suited for production and prototype drilling operations where a renewable bushing is not required. The headless press fit design keeps the bushing flush with the jig plate surface, making it appropriate for close-clearance drilling setups. It is used in metal fabrication shops, machine shops, and manufacturing facilities where consistent hole location is critical. The PM industry code designation conforms to ANSI standards for drill bushing interchangeability.

Key Features

Compatibility

Designed as an OEM-style replacement or new-installation component for drill jigs and fixtures requiring a PM-series press fit headless bushing with a 3.8 mm inside diameter conforming to ANSI standards.

Installation Notes

Press fit bushings are installed by qualified machinists or tool and die technicians using an arbor press or hydraulic press to seat the bushing flush and square in the jig plate bore. The jig plate bore must be machined to the correct interference fit tolerance before installation. Once pressed in, the bushing is not designed for removal or replacement. Ensure the jig plate is secured and the bore is clean and free of burrs before pressing.
