Boneham AM00000652 Drill Bushing Pm 6.9 in Id Steel

Product Description

The BONEHAM AM00000652 is a press fit headless drill bushing rated to industry code PM, designed to guide drill bits with precision in metalworking and machining operations. With an inside diameter of 6.9 inches and a body outside diameter of 12.00 millimeters, this bushing is installed directly into a jig plate without a retaining head, providing a flush, low-profile fit. Manufactured from steel hardened to 60 to 65 HRC, it delivers the wear resistance required for repetitive drilling cycles in production environments. Machinist and toolroom professionals install this part as a fixed liner or renewable guide component in drill jig assemblies.

This bushing suits applications in metal fabrication shops, production machining cells, and tooling rooms where consistent hole location accuracy is required. The PM industry code designation identifies it as a standard press fit type per ANSI specifications, making it a direct fit in jig plates designed around that standard. It is appropriate for use in both light and moderate-duty drilling operations where a non-renewable, permanent-style bushing is acceptable.

Key Features

• Press fit installation method - no flange or retaining head for a flush, compact profile
• PM industry code classification per ANSI standards
• Steel construction hardened to 60 to 65 HRC for extended wear life
• Inside diameter tolerance of +0.005 to +0.014 mm for precise bit guidance
• Non-renewable design - intended as a permanent fixed liner in the jig plate
• Overall bushing length of 20.00 mm suitable for standard jig plate thicknesses

Compatibility

Designed as an ANSI-standard PM-code press fit headless drill bushing for use in drill jig plates requiring a permanent, non-renewable liner with a 6.9-inch inside diameter.

Installation Notes

Installation is performed by machinists or toolmakers using an arbor press or hydraulic press to seat the bushing flush into the jig plate bore. Ensure the receiving bore is machined to the correct interference fit tolerance before pressing in. Do not hammer the bushing directly without a proper driver to avoid deformation of the bore or bushing face. Once pressed in, this bushing is not designed for removal and replacement during service.
