Hole saws are great accessories, but attaching them to drills has always been a tedious and precision-demanding task. Professionals spend time and money on this. With EXPERT Power Change Plus, you can change hole saws in seconds, thanks to Bosch's smart one-click attachment. This keyless system does not require attachment with screws or bolts. Simply pull one hole saw out and push another one in.
Despite its apparent simplicity, EXPERT Power Change Plus still ensures a secure connection: with a reinforced shaft and a closely opposing guide drill, it actually gives less play than conventional systems.
The hole saw system Bosch EXPERT Power Change Plus is designed to give hole saw users the best connectivity with maximum efficiency. It saves your time and performs the toughest tasks at a high level.
