Boneham P2022EC Press Fit Headless Drill Bushing

Product Description

The BONEHAM P2022EC is a press fit headless drill bushing designed to guide cutting tools with precision during drilling, reaming, and boring operations. This bushing features a 0.136 inch (No. 29 wire gauge) inside diameter, a 5/16 inch body outside diameter, and an overall length of 1-3/8 inches. Manufactured from steel and hardened to 60-65 HRC, the P2022EC delivers the wear resistance and dimensional stability required for production drilling jigs and fixture tooling. It meets ANSI standards and is designed for permanent installation without a locking collar or head flange.

This bushing is suited for use in precision drill jigs, fixture plates, and tooling assemblies in metalworking, machining, and general manufacturing environments. The headless design allows flush seating within a counterbored hole, making it well-suited for confined or tight-clearance jig configurations where a headed bushing would interfere with the workpiece or clamping setup. The P2022EC is a non-renewable type, intended for fixed, long-term installation.

Key Features

• Press fit installation method for permanent, secure seating in drill jig plates
• Headless design allows flush or below-surface mounting in counterbored holes
• Inside diameter: 0.136 inches (No. 29 wire gauge) with a tight tolerance of +0.0001 to +0.0004 inches
• Body outside diameter: 5/16 inches; overall length: 1-3/8 inches
• Steel construction hardened to 60-65 HRC for extended wear life
• Counterbored and ANSI-compliant; non-renewable fixed design

Compatibility

Designed as an ANSI-standard P-series press fit headless drill bushing for use in compatible drill jig fixtures requiring a 5/16 inch outside diameter bushing seat.

Installation Notes

Installation is performed by machinists or toolmakers using a press or arbor press to seat the bushing into a properly toleranced counterbored hole in the jig plate. Ensure the mating hole is machined to the correct interference fit before pressing to avoid bushing distortion or damage to the jig. Because this is a non-renewable bushing, removal after installation may damage the surrounding fixture material. Always deburr and clean the mounting hole before pressing the bushing into place.
