Boneham PT126DA Press Fit Headless Drill Bushing

Product Description

The BONEHAM PT126DA is a press fit headless drill bushing designed to guide twist drills and other cutting tools with precision during machining and fabrication operations. Built to ANSI standards, this bushing features a 0.0995 inch inside diameter, a 3/16 inch body outside diameter, and a 3/8 inch overall length. Manufactured from steel with a hardness of 60 to 65 HRC, it delivers the wear resistance required for repetitive drilling cycles in jig and fixture applications. The headless profile allows flush installation in jig plates where a protruding flange would interfere with workpiece seating.

This bushing is suited for use in drill jigs and production fixtures where consistent hole location is critical. The press fit installation method locks the bushing permanently into the jig plate bore, making it appropriate for fixed, high-volume drilling operations where tooling does not need to be exchanged between setups. It is not renewable once pressed in. Machinists, tool and die makers, and fixture builders are the primary installers of this component.

Key Features

• Press fit installation for permanent, vibration-resistant seating in jig plates
• Headless design allows flush mounting where flanged bushings cannot be used
• Steel construction hardened to 60 to 65 HRC for long service life in repetitive drilling applications
• Inside diameter tolerance of +0.0001 to +0.0004 inches for precise drill guidance
• Meets ANSI standards for drill bushing geometry and dimensional accuracy
• Bushing Industry Code P for straightforward cross-referencing

Compatibility

Designed as an OEM-style replacement or direct-fit component for drill jigs and fixtures requiring a permanent press fit headless bushing with a 0.0995 inch ID and 3/16 inch OD per ANSI specifications.

Installation Notes

Press fit bushings are installed by a machinist or tool and die maker using an arbor press or hydraulic press. 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 removable without damaging the jig plate. Ensure the plate and bushing are free of burrs, chips, and contaminants before pressing to achieve full seating depth.
