Boneham AM00000471 Press Fit Headless Drill Bushing Pm

Product Description

The BONEHAM AM00000471 is a press fit headless drill bushing designed to guide drill bits with precision in jig and fixture applications. Manufactured from steel and designated with industry code PM, this bushing features a 19-inch inside diameter, a 30-millimeter body outside diameter, and an overall length of 45 millimeters. It installs without a locking head or retaining ring, seating directly into a prepared hole in a drill jig for a clean, flush fit. Machinists, tool and die makers, and fixture builders rely on this type of bushing to maintain accurate hole location and extend the service life of drilling fixtures in production environments.

This bushing is suited for use in metalworking drill jigs and fixtures where repeatable hole positioning is required. The press fit installation method makes it appropriate for permanent or semi-permanent fixture setups. It is a single-piece, non-renewable bushing, meaning it is intended to remain in place once pressed in rather than be swapped out for different drill sizes. Typical applications include production drilling, reaming, and boring operations where consistent alignment across multiple workpieces is critical.

Key Features

• PM industry code designation for press fit headless drill bushing type
• Steel construction for durability and wear resistance in drilling applications
• 19-inch inside diameter to accommodate corresponding drill or tool shank
• 30-millimeter body outside diameter for secure seating in jig plate
• 45-millimeter overall bushing length for adequate tool guidance depth
• Non-renewable design - press fit for permanent fixture installation

Compatibility

Designed as an OEM-style replacement or direct-fit component for steel drill jigs and fixtures requiring a PM-code press fit headless bushing with a 19-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 a properly sized jig plate bore. Ensure the receiving hole is machined to the appropriate interference fit tolerance before pressing to avoid bushing damage or misalignment. Do not hammer the bushing in directly without a driver or press tool, as this can distort the bore or damage the bushing face. Always verify inside diameter clearance with the intended drill or reamer before final installation.
