Boneham AM00000679 Drill Bushing Pm 7.7 Inch Id

Product Description

The BONEHAM AM00000679 is a press fit headless drill bushing with a PM industry code, designed to guide drill bits with precision in fixed jig tooling applications. Manufactured from hardened steel with a hardness rating of 60 to 65 HRC, it delivers the wear resistance required for repetitive drilling operations. The bushing features a 7.7-inch inside diameter and a body outside diameter of 12.00 mm, with an overall length of 10.00 mm. It is installed using an interference press fit and is not renewable once seated. Machinists, tool and die makers, and precision fabrication technicians install this component during jig and fixture assembly.

This bushing is suited for use in drill jig tooling where consistent hole location accuracy is critical across production runs. Its headless profile sits flush with the jig plate surface, making it appropriate for applications where a protruding flange would interfere with workpiece clearance. Typical use cases include production machining environments in industrial and manufacturing settings where ANSI-standard tooling components are specified.

Key Features

• Press fit installation method for secure, fixed seating in the jig plate
• PM bushing industry code per ANSI standards
• Hardened steel construction rated 60 to 65 HRC for extended wear life
• Inside diameter tolerance of +0.005/+0.014 mm for precise drill guidance
• Headless design allows flush mounting with no protruding flange
• Not renewable — intended as a permanent press fit installation

Compatibility

Designed as an ANSI-standard PM-code press fit headless drill bushing for use in fixed drill jig and fixture applications where a permanent, non-renewable bushing is required.

Installation Notes

Installation is performed by tool and die makers or precision machinists using an arbor press or hydraulic press to seat the bushing into the jig plate bore. Verify bore diameter and surface finish in the jig plate before pressing to ensure proper interference fit. Once pressed into position, the AM00000679 is not intended to be removed or replaced. Follow applicable shop safety procedures and ANSI tooling standards during installation.
