Boneham AM00000634 Press Fit Headless Drill Bushing

Product Description

The BONEHAM AM00000634 is a press fit headless drill bushing manufactured from steel and designed to guide drill bits with precision during machining operations. Assigned industry code PM, this bushing features an inside diameter of 6.4 inches, a body outside diameter of approximately 0.472 inches (12.00 mm), and an overall length of approximately 0.787 inches (20.00 mm). It installs without a head flange, keeping a low profile in jig plates where flush seating is required. This is a non-renewable bushing, meaning it is pressed permanently into the jig body. Machinists and tool-and-die professionals install this type of bushing in drill jigs to maintain consistent hole location across production runs.

This bushing is suited for use in drill jig assemblies where controlled hole placement and repeatable accuracy are critical. It is appropriate for general metalworking, fabrication shops, and production machining environments. The press fit design locks the bushing securely into the jig body, making it well suited for moderate-to-high volume drilling applications where bushing removal is not required between production runs.

Key Features

• Press fit installation for secure, permanent seating in jig plates
• Headless design provides flush, low-profile fit in close-tolerance jig bodies
• Inside diameter of 6.4 inches for precise drill bit guidance
• Steel construction for durability in production drilling environments
• Non-renewable design eliminates flange interference in tight jig layouts
• PM industry code for standardized bushing identification and sourcing

Compatibility

Designed as an OEM-style replacement or standard component for press fit headless drill jig bushing applications conforming to PM industry code specifications.

Installation Notes

Installation is performed by pressing the bushing into a prepared jig plate bore using an arbor press or hydraulic press - never drive with a hammer, as this can damage the bushing or distort the bore. Ensure the receiving hole is machined to the correct press fit tolerance before installation. This is a permanent installation; the bushing is not designed for removal and reinstallation. Follow applicable shop safety procedures and power down any associated machinery before servicing jig assemblies.
