Boneham P5622LK Headless Drill Bushing 1/2 Id Steel

Product Description

The BONEHAM P5622LK is a press fit headless drill bushing designed to guide cutting tools with precision in jig and fixture applications. Manufactured from steel with a hardness rating of 60 to 65 HRC, it delivers consistent bore alignment under repeated use. The bushing features a 0.5-inch inside diameter, a 0.875-inch outside diameter, and an overall length of 1.375 inches. It installs without a head for flush or countersunk applications where a protruding flange is not acceptable. Machinists, toolmakers, and maintenance technicians rely on this type of bushing to maintain hole location accuracy across production runs.

This bushing is suited for use in drill jigs, fixtures, and tooling plates in machine shop, manufacturing, and industrial maintenance environments. The P series headless style is appropriate where the bushing must seat flush with the fixture surface. The inside diameter tolerance of plus 0.0001 to plus 0.0005 inches ensures consistent tool guidance for standard 0.5-inch shank drills, reamers, and similar cutting tools. This part meets ANSI standards and is sold individually.

Key Features

• Press fit installation method — no fasteners or locking mechanisms requiredHeadless design seats flush with fixture or jig plate surfaces
• Steel construction hardened to 60 to 65 HRC for wear resistance
• Inside diameter tolerance of plus 0.0001 to plus 0.0005 inches for precise tool guidance
• Meets ANSI standards for drill bushing dimensions and tolerances
• Non-renewable fixed bushing for permanent or long-run tooling setups

Compatibility

Designed as an OEM-style fixed drill bushing compatible with standard drill jig fixtures requiring a press fit headless bushing with a 0.5-inch inside diameter and 0.875-inch outside diameter per ANSI specifications.

Installation Notes

Press fit bushings are typically installed by a machinist or toolmaker using an arbor press or hydraulic press — never drive with a hammer directly on the bushing face. 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 for removal and replacement. Confirm tool shank diameter against bushing ID tolerance before installation.
