Boneham PT125CN Press Fit Headless Drill Bushing Steel

Product Description

The BONEHAM PT125CN is a press fit headless drill bushing designed to guide cutting tools with precision in jig and fixture applications. Manufactured from steel, this type P bushing features an inside diameter of 0.086 inches (wire gauge No. 44) with a close tolerance of +0.0001 to +0.0004 inches, a body outside diameter of 3/16 inches, and an overall length of 5/16 inches. It installs without a head, keeping it flush with the jig plate surface. Machinists, toolmakers, and fixture builders use this bushing to maintain accurate hole location and consistent drill guidance across production runs.

This bushing is suited for use in drill jigs and fixture plates where a permanent, non-renewable press fit installation is required. The headless design is appropriate when a flush or sub-flush installation is needed and clearance above the jig plate is limited. Its compact dimensions make it a practical choice for close-center hole patterns and high-density fixture layouts in both job shop and production environments.

Compatibility

Designed as an OEM-style replacement or new-build component for standard drill jig and fixture plates requiring a type P press fit headless bushing with a 0.086 inch inside diameter and 3/16 inch outside diameter.

Installation Notes

Press fit bushings are typically installed by toolmakers or machinists using an arbor press. The receiving bore in the jig plate must be machined to the specified interference fit tolerance before installation. Do not hammer the bushing in directly without a press or driver to avoid misalignment or damage to the bushing bore. Once pressed in, this bushing is not designed for removal and reuse.
