Cordless Innovation Built on a Proven Legacy

Building on the trusted performance of the original Master-Lee stud hole cleaner, the Battery Powered Stud Hole Cleaner introduces enhanced freedom and mobility without sacrificing the rugged reliability that maintenance crews have relied on for decades. This cordless model brings the same proven cleaning power—now in a more flexible, operator-friendly form.

Eliminating the need for power cords enhances both safety and maneuverability, reducing trip hazards and simplifying work in tight or obstructed areas around the reactor vessel. This makes it an ideal solution for environments where cord management can complicate workflow or introduce risks during critical path operations.

Purpose-built for cleaning the stud holes of reactor vessels, the tool features a rotating brush driven by a rechargeable battery-powered motor, delivering consistent torque and performance throughout the cleaning process. The operator can easily adjust the brush insertion depth to match the hole geometry, ensuring complete and uniform cleaning.

To support proper alignment and reduce physical strain, the design incorporates a centering guide that stabilizes the tool inside the reactor head stud hole opening. The system also includes a built-in vacuum port, allowing for connection to an external vacuum to actively remove debris during use—maintaining cleanliness and minimizing post-cleaning tasks.

Field teams benefit from the mobility of cordless operation combined with the heritage of the Master-Lee design, which has been successfully used in outage settings for years. The battery-powered model carries that reputation forward, offering an ALARA-conscious, user-friendly solution that improves safety, efficiency, and job site cleanliness.
