The Power Change Plus system offers greater robustness and precision than its predecessor. Its reinforced shank ensures better tolerances, less backlash and greater precision. It also provides better guidance thanks to the centring drill. The unique keyless system requires only a simple click to remove the hole saw, enabling quick and easy core ejection. This system can be used as a keyless connection between power tools and hole saws. Suitable for all cordless and mains-powered screwdrivers. Diameter mm: 8.7
