Boneham PT3612IF Press Fit Headless Drill Bushing Steel

Product Description

The BONEHAM PT3612IF is a press fit headless drill bushing designed to guide cutting tools with precision during drilling operations. Classified under industry code P, this bushing features a 19/64-inch inside diameter and a 9/16-inch outside diameter, with an overall length of 3/4 inch. Constructed from steel, it delivers the hardness and wear resistance required for production drilling jigs and fixtures. The headless design allows flush installation without a protruding flange, making it well suited for close-tolerance tooling applications. Installation is accomplished by pressing the bushing directly into a prepared hole in the drill jig plate.

This bushing is used in machine shop and manufacturing environments where repeatable hole location accuracy is required. It fits into drill jig plates and tooling fixtures used for production runs in metalworking, fabrication, and assembly operations. The P-series press fit style is a widely recognized industry standard for permanent bushing installations where the bushing is not intended to be routinely replaced during a production run. Machinists, toolmakers, and fixture builders are the primary installers of this component.

Key Features

• 19/64-inch inside diameter with a tight tolerance of +0.0001 to +0.0005 inches for precise tool guidance
• 9/16-inch outside diameter for a secure press fit into standard jig plate bores
• 3/4-inch overall length provides adequate depth for stable drill guidance
• Headless design allows flush seating with the jig plate surface
• Steel construction resists wear and deformation under repeated drilling cycles
• Non-renewable press fit style intended for permanent installation

Compatibility

Designed as an OEM-style replacement or new-installation component for drill jigs and fixtures requiring a P-series press fit headless bushing with a 19/64-inch inside diameter and 9/16-inch outside diameter.

Installation Notes

Installation is performed by toolmakers or machinists using a press or arbor press to seat the bushing flush into the jig plate bore. The receiving hole in the jig plate must be machined to the appropriate interference fit tolerance before pressing. Do not use a hammer directly on the bushing face, as this can damage the bore or distort the bushing. This is a permanent, non-renewable bushing and is not intended for removal and reinstallation once pressed into place.
