Boneham PT2812HW Press Fit Headless Drill Bushing

Product Description

The BONEHAM PT2812HW is a press fit headless drill bushing designed to guide drill bits and other cutting tools with precision during machining and fabrication operations. Built from steel, this bushing features a 0.281 inch inside diameter, a 7/16 inch body outside diameter, and a 3/4 inch overall length. The headless profile allows the bushing to sit flush within a drill jig plate, making it well suited for applications where a protruding flange would interfere with the workpiece or tooling setup. It is a fixed, non-renewable bushing intended for permanent press fit installation in jig tooling.

This bushing is used in drill jig applications across metalworking, fabrication, and precision machining environments. It is appropriate for both production and maintenance shop settings where repeatable hole location accuracy is required. The P industry code designates its dimensional series, and the inside diameter tolerance of plus 0.0001 to plus 0.0005 inches ensures consistent tool guidance across repeated drilling cycles. Machinists and toolmakers are the primary installers of this component.

Key Features

• Press fit installation method for permanent, stable seating in jig plates
• Headless design allows flush mounting with no protruding flange
• 0.281 inch inside diameter with tight tolerance of plus 0.0001 to plus 0.0005 inches for accurate tool guidance
• Steel construction provides durability under repeated drilling operations
• Non-renewable fixed bushing intended for long-term jig tooling use
• Compact 3/4 inch overall length suits thin and standard jig plate thicknesses

Compatibility

Designed as an OEM-style replacement or new-installation drill bushing for steel jig plates requiring a press fit headless style in the P industry code dimensional series.

Installation Notes

Installation is performed by toolmakers or machinists using an arbor press or hydraulic press to seat the bushing flush into a properly reamed jig plate bore. The receiving bore must be machined to the appropriate interference fit tolerance before pressing to avoid bushing damage or misalignment. Do not hammer the bushing directly without a driver to prevent distortion of the bore or bushing ID. Always verify inside diameter clearance with the intended drill or tool shank before committing the bushing to a permanent jig plate installation.
