The Power Change Plus system offers greater robustness and precision than its predecessor. Its reinforced shank ensures better tolerances, produces less play and greater accuracy. It also enables better guidance thanks to the centering drill. The unique keyless system requires only a simple click to remove the hole saw, allowing quick and easy ejection of the drill core. This system is to be used as a keyless connection between power tools and hole saws. It is suitable for all cordless and corded drill drivers.
