The Power Change Plus System offers more robustness and precision than its predecessor. Its reinforced shank provides improved tolerances, creating less play and greater accuracy. Additionally, it enables better guidance, due to its pilot drill bit. Its unique keyless system only requires one simple click to unplug the hole saw, offering fast and easy plug ejection. Use this system as a keyless connection between power tools and hole saws. It is suitable for use with all corded and cordless drill drivers.
