Boneham PT2810HG Press Fit Headless Drill Bushing

Product Description

The BONEHAM PT2810HG is a press fit headless drill bushing designed to guide drill bits and reamers with precision in jig and fixture applications. It features a 0.25-inch inside diameter, a 7/16-inch (0.4375-inch) body outside diameter, and a 5/8-inch (0.625-inch) overall length. Manufactured from steel and hardened to 60-65 HRC, this bushing delivers the wear resistance required for repeated drilling operations in production environments. The headless design allows it to sit flush within the jig plate, keeping the work surface clear. Inside diameter tolerance is held to +0.0001 to +0.0004 inches for consistent, repeatable hole location. Licensed machinists, toolmakers, and fixture builders typically specify and install this component.

This bushing is suited for use in drill jigs, fixture plates, and tooling assemblies where a permanent, non-renewable press fit installation is required. The P industry code designation follows ANSI standards for drill bushing sizing and interchangeability, making it straightforward to specify on engineering drawings. It is commonly used in metalworking, fabrication, and precision machining shops handling repetitive hole-drilling operations that demand tight positional accuracy across multiple workpieces.

Key Features

• Press fit installation — no set screw or locking collar required
• Headless design sits flush with jig plate surface
• 0.25-inch inside diameter with +0.0001 to +0.0004 inch tolerance
• Hardened steel construction at 60-65 HRC for extended wear life
• ANSI standard P-series industry code for drawing specification compatibility
• Non-renewable fixed bushing intended for permanent installation

Compatibility

Designed as an ANSI-standard P-series press fit headless drill bushing suitable for use in drill jigs and fixture plates requiring a 7/16-inch diameter installation bore and a 0.25-inch nominal drill guide.

Installation Notes

Press fit bushings are installed by toolmakers or machinists using an arbor press or hydraulic press — never hammer directly on the bushing face, as this can damage the bore or distort the outer diameter. The receiving hole in the jig plate must be machined to the correct interference fit tolerance before installation. Once pressed in, this bushing is not intended for removal or replacement. Always verify bore alignment before pressing to final depth.
