Boneham P4816LR Press Fit Headless Drill Bushing

Product Description

The BONEHAM P4816LR is a press fit headless drill bushing manufactured from steel, designed to guide drill bits and cutting tools with precision in jig and fixture applications. With an inside diameter of 17/32 inches and a body outside diameter of 3/4 inches, this bushing accepts standard drill shanks and maintains accurate hole location under repeated use. The 1-inch overall length provides sufficient bearing surface for stable tool guidance. Installation is by press fit, seating the bushing permanently into the jig plate without a retaining head. Machinists, toolmakers, and fixture builders working in job shops, production environments, and maintenance settings are the primary installers.

This bushing fits into drill jig plates and fixture bodies where permanent, non-renewable bushing installation is required. Industry code P designates its dimensional series, making it straightforward to specify as a direct replacement or original component in standard P-series jig setups. It is suited for production drilling, reaming guidance, and precision hole location in both manual and CNC-assisted fixture work. Applications span metal fabrication, general machining, and assembly tooling across industrial and commercial manufacturing environments.

Key Features

• Press fit installation for permanent, non-renewable seating in jig plates
• Headless design sits flush with the jig plate surface, eliminating interference with workpiece or tooling clearance
• 17/32 inches inside diameter with a tight tolerance of +0.0001 to +0.0005 inches for precise drill guidance
• 3/4 inches body outside diameter conforming to P-series industry dimensional standards
• 1-inch overall length provides adequate bearing surface for accurate tool alignment
• Steel construction for durability and wear resistance in repeated-use drilling operations

Compatibility

Designed as a standard P-series press fit headless drill bushing for use in drill jig plates and tooling fixtures requiring a permanent bushing with a 3/4 inches outside diameter press fit seat.

Installation Notes

Installation is performed by toolmakers or machinists using an arbor press or hydraulic press to seat the bushing flush into the jig plate bore. The receiving bore in the jig plate must be machined to the appropriate press fit tolerance before installation. Once pressed in, the bushing is not intended to be removed or replaced. Always verify bore dimensions and alignment before pressing to avoid bushing distortion or plate damage.
