Boneham AM00000477 Press Fit Headless Drill Bushing Pm

Product Description

The BONEHAM AM00000477 is a press fit headless drill bushing manufactured to ANSI standards in steel with a hardness of 60 to 65 HRC. Carrying the industry code PM, this bushing is designed to guide drill bits and cutting tools with precise, repeatable accuracy during machining and fabrication operations. The inside diameter measures 2.65 inches, with a tolerance of +0.002/+0.008 mm, ensuring consistent bore guidance across production runs. The headless design allows the bushing to sit flush within the jig plate. This component is installed by machinists, toolmakers, and precision fabrication professionals working with drill jigs and fixture setups.

This bushing is suited for use in drill jig applications where a permanent, non-renewable press fit installation is required. With a body outside diameter of 6.00 mm and an overall length of 8.00 mm, it fits compact jig plates and close-tolerance fixture configurations. The steel construction and high Rockwell hardness rating make it appropriate for high-cycle drilling operations in industrial and manufacturing environments where dimensional accuracy and wear resistance are critical.

Key Features

• Press fit installation method for permanent, secure seating in jig plates
• PM industry code classification per ANSI standards
• Inside diameter of 2.65 inches with tolerance of +0.002/+0.008 mm
• Hardness rated 60 to 65 HRC for extended wear life in high-cycle applications
• Headless design allows flush mounting within the fixture
• Non-renewable design intended for fixed, long-term installations

Compatibility

Designed as an OEM-style press fit headless drill bushing conforming to ANSI standards, suitable for use in standard drill jig plates and machining fixtures requiring a PM-coded permanent bushing.

Installation Notes

Press fit bushings are installed by toolmakers or precision machinists using an arbor press or hydraulic press to seat the bushing flush and square within the jig plate bore. Power down and de-energize all associated machinery before beginning fixture modification or bushing replacement. Verify bore dimensions in the jig plate before installation, as press fit components are not designed for removal once seated. Follow applicable shop safety procedures and manufacturer guidelines for press fitting steel components.
