Boneham P6416MR Press Fit Headless Drill Bushing

Product Description

The BONEHAM P6416MR is a press fit headless drill bushing designed to guide cutting tools with precision in metalworking and machining applications. Classified under Industry Code P, this bushing features an inside diameter of 11/16 inches (0.6875 inches decimal) and a body outside diameter of 1 inch, with an overall length of 1 inch. Manufactured from steel and hardened to 60 to 65 HRC, the P6416MR delivers the wear resistance and dimensional stability required for accurate, repeatable hole drilling in production and tooling environments. The headless design allows flush seating in a jig plate without an exposed flange. Licensed machinists and toolroom technicians are the primary installers.

This bushing is suited for use in drill jigs and fixture plates across general manufacturing, precision machining, and toolroom fabrication. The press fit installation method means the bushing is permanently seated into the jig body, making it appropriate for high-volume production setups where the bushing position does not require frequent change. The inside diameter tolerance of +0.0001 to +0.0005 inches ensures close guidance of standard drill sizes in the 11/16-inch range, maintaining positional accuracy across repeated drilling cycles.

Key Features

• Industry Code P press fit headless configuration for permanent jig installation
• Inside diameter of 0.6875 inches with a tolerance of +0.0001 to +0.0005 inches for precise drill guidance
• Steel construction hardened to 60 to 65 HRC for extended wear life
• Overall length of 1 inch and 1-inch OD for consistent seating in standard jig plates
• Non-renewable design suited to fixed, high-volume drilling operations
• Conforms to ANSI standards for dimensional interchangeability

Compatibility

Designed as an ANSI-standard press fit headless drill bushing for use in drill jigs and fixture plates requiring a P-series bushing with an 11/16-inch inside diameter and 1-inch outside diameter.

Installation Notes

Press fit bushings are installed by toolroom machinists or fixture builders using an arbor press or hydraulic press to drive the bushing flush with the jig plate surface. The receiving bore in the jig plate must be machined to the correct interference fit tolerance before installation. Once pressed in, this non-renewable bushing is not designed for removal and replacement. Always verify jig plate material hardness and bore finish before pressing to avoid bushing distortion or dimensional shift.
