Boneham AM00000574 Press Fit Drill Bushing Pm 4.7 in

Product Description

The BONEHAM AM00000574 is a press fit headless drill bushing with an industry code designation of PM, used to guide drill bits with precision during machining and fabrication operations. Manufactured from steel, this bushing is designed for permanent installation using a press fit method, seating securely into a drill jig or fixture plate without the need for locking hardware or a head flange. The inside diameter measures 4.7 inches, the body outside diameter measures 8.00 millimeters, and the overall bushing length is 16.00 millimeters. It is a non-renewable type, meaning it is intended for fixed, long-term installation rather than field replacement during a job run.

This bushing is suited for use in production machining environments, tool shops, and jig-and-fixture fabrication. It is appropriate for applications where consistent hole location and drill guidance are required across repeated operations. The headless design allows the bushing to sit flush with the jig plate surface, making it well suited for close-tolerance work where a flanged bushing would interfere with workpiece clamping or mating surfaces. Machinists, tool-and-die makers, and fixture builders are the primary installers of this component.

Key Features

• Press fit installation method for permanent, secure seating in jig plates and fixture bodies
• PM industry bushing code designation for standardized sizing and interchangeability
• Inside diameter of 4.7 inches for precise drill bit guidance
• Headless design allows flush mounting with jig plate surface
• Steel construction for durability in repeated drilling operations
• Non-renewable type intended for fixed, permanent installation

Compatibility

Designed as a standard PM-code press fit headless drill bushing for use in machining jigs and fixture plates requiring a permanently installed, flush-mount drill guide.

Installation Notes

Installation is performed by pressing the bushing into a properly sized and toleranced hole in the jig plate using a hydraulic or arbor press. The receiving hole must be machined to the correct interference fit tolerance for the outside diameter before installation. Do not drive the bushing with a hammer or mallet, as this can distort the bore or damage the seating surface. Once pressed in, the bushing is not intended to be removed or replaced.
