Boneham P3222HL Press Fit Headless Drill Bushing Steel

Product Description

The BONEHAM P3222HL is a press fit headless drill bushing manufactured from steel with a hardness of 60 to 65 HRC. It features a 0.261-inch inside diameter, a 1/2-inch body outside diameter, and an overall length of 1-3/8 inches. Designed for permanent installation in drill jigs and fixture plates, this bushing guides drill bits, reamers, and other cutting tools with repeatable precision. The headless design allows the bushing to sit flush with the jig plate surface, making it well suited for applications where a protruding head would interfere with workpiece clearance or tool travel. Installation is by press fit, requiring no additional fasteners or locking hardware.

This bushing is used in machine shop, tool and die, and production drilling applications where a fixed, non-renewable guide bushing is required. It conforms to ANSI standards and carries the industry code P, which designates its dimensional series. Typical applications include drill jig fixtures used in metalworking, fabrication, and precision machining environments. It is installed by toolmakers, machinists, and fixture builders working on production or prototype drilling operations.

Key Features

• Press fit installation method — no locking collar or set screw required
• Headless design allows flush mounting in jig plates
• Steel construction hardened to 60 to 65 HRC for wear resistance
• Inside diameter tolerance of +0.0001 to +0.0005 inches for consistent tool guidance
• Counterbored design for secure seating in the host fixture
• Conforms to ANSI standards; industry code P dimensional series

Compatibility

Designed as a permanent press fit drill bushing for use in ANSI-standard drill jig fixtures requiring a P-series headless bushing with a 0.261-inch inside diameter and 1/2-inch outside diameter.

Installation Notes

Press fit bushings are installed by toolmakers or machinists using an arbor press or hydraulic press sized for the bushing OD and fixture bore. The receiving bore in the jig plate must be machined to the correct interference fit tolerance before installation. Once pressed in, this bushing is not intended to be removed or replaced. Always de-energize and lock out any associated machinery before performing fixture maintenance or bushing installation.
