Boneham AM00000740 Press Fit Headless Drill Bushing Pm

Product Description

The BONEHAM AM00000740 is a press fit headless drill bushing conforming to industry code PM, designed to guide drill bits with precision in jig and fixture applications. Machined from steel, this bushing features an inside diameter of 0.370 inches (9.40 mm) and an overall length of 0.472 inches (12.00 mm). It installs permanently into a drill jig plate via press fit, requiring no locking collar or retaining hardware. Machinists, tool and die makers, and fixture builders use this bushing to maintain accurate hole location and extend the working life of drill jigs in production and repair environments.

This bushing is suited for use in drill jigs, fixture plates, and production tooling where a permanent, non-renewable guide bushing is required. The headless PM-style profile sits flush with or below the jig plate surface, making it appropriate for applications where a protruding flange would interfere with workpiece seating or clamping. It is commonly installed in both light manufacturing and heavy production shops handling repetitive drilling operations on metal, plastic, or composite workpieces.

Key Features

• Press fit installation - no collar or locking ring required for permanent seating
• PM industry code headless profile seats flush with jig plate surface
• Inside diameter of 0.370 inches (9.40 mm) for precise drill guidance
• Overall bushing length of 0.472 inches (12.00 mm)
• Steel construction for durability in repetitive drilling applications
• Non-renewable design - intended as a permanent press fit installation

Compatibility

Designed as an OEM-style replacement or new-installation press fit headless drill bushing for drill jigs and fixture plates requiring a PM-style guide bushing with a 0.370 inch (9.40 mm) inside diameter.

Installation Notes

Press fit bushings are typically installed by a machinist or toolmaker using an arbor press to drive the bushing squarely into a properly toleranced hole in the jig plate. Ensure the receiving bore is machined to the correct interference fit tolerance before pressing. Do not use a hammer directly on the bushing face, as this can damage the bore geometry. Removal of a pressed bushing generally requires destruction of the bushing, as the PM type is non-renewable.
