Boneham PT2810HD Press Fit Headless Drill Bushing

Product Description

The BONEHAM PT2810HD is a press fit headless drill bushing used to guide drill bits and other cutting tools with precision in jig and fixture applications. Classified under Industry Code P, this bushing features a 0.246 inch (Letter D) inside diameter and a 7/16 inch outside diameter, with an overall length of 5/8 inch. Machined from steel for durability in production drilling operations, it is installed directly into a drill jig plate without the use of a head flange, keeping the profile flush with the workpiece surface. Licensed machinists, toolmakers, and precision manufacturing technicians are the primary installers of this component.

The PT2810HD is suited for fixed jig applications where the bushing is pressed permanently into the jig body and does not require removal between operations. The headless design makes it appropriate for installations where clearance above the jig plate surface is restricted. It is commonly used in metalworking, assembly line fixturing, and production drilling setups where repeatable hole location accuracy is required.

Key Features

• Press fit installation method — no additional fasteners required
• Headless design for flush, low-profile mounting in jig plates
• 0.246 inch inside diameter (Letter D, Industry Code P) with a close inside diameter tolerance of +0.0001 to +0.0004 inches
• 7/16 inch body outside diameter and 5/8 inch overall length
• Steel construction for wear resistance in repetitive drilling applications
• Non-renewable (fixed) bushing — intended for permanent installation

Compatibility

Designed as an OEM-style replacement or direct-fit component for drill jigs requiring an Industry Code P, headless, press fit bushing with a 0.246 inch inside diameter and 7/16 inch outside diameter.

Installation Notes

Installation is typically performed by toolmakers or machinists using an arbor press or hydraulic press to seat the bushing flush within a prepared jig plate bore. The receiving bore in the jig plate should be machined to the appropriate interference fit tolerance before pressing. Verify bore diameter and surface finish prior to installation to avoid galling or misalignment. Once pressed in, this bushing is not designed for removal and reinstallation.
