Boneham P166CY Press Fit Headless Drill Bushing

Product Description

The BONEHAM P166CY is a press fit headless drill bushing designed to guide cutting tools accurately through jigs and fixtures in precision metalworking and fabrication applications. Classified under Industry Code P, this bushing features a 0.098 inch (No. 40 wire gauge) inside diameter with a tightly held tolerance of +0.0001 to +0.0004 inches, ensuring consistent hole placement across repeated operations. The body outside diameter measures 1/4 inch with an overall length of 3/8 inch. Manufactured from steel hardened to 60 to 65 HRC, it delivers the wear resistance required for high-cycle drilling operations. Machinists, tool and die makers, and jig builders are the primary installers.

This bushing is suited for use in drill jig assemblies where a permanent, non-renewable liner is acceptable. The headless profile allows flush installation into jig plates without surface protrusion, making it appropriate for close-tolerance fixtures used in production environments. Its press fit installation method provides a secure, interference-fit hold within a prepared bore. The part conforms to ANSI standards, making it compatible with standard jig and fixture design practices in both job shop and production machine shop settings.

Compatibility

Designed as an ANSI-standard press fit headless drill bushing for use in drill jigs and fixtures requiring a permanent, non-renewable bushing of Industry Code P classification.

Installation Notes

Press fit bushings are installed by machinists or toolmakers using an arbor press or similar controlled pressing equipment to avoid damage to the bushing bore or host jig plate. The receiving bore in the jig plate must be machined to the appropriate interference fit tolerance before installation. Once pressed in, this bushing is not intended for removal or replacement. Power down all associated machinery before performing any jig maintenance or bushing installation work.
