With this adjustable hole saw, you can drill all hole diameters from 45 to 130 mm. You only need one product for many diameters. The 3 groups of three teeth saw effortlessly through plasterboard and softwood panels and ensure fine and clean cuts with their special set teeth. The size is set in 3 simple steps: loosening, synchronised adjustment and fixing. The integrated millimetre scale and other scales for standard installation diameters help you to find the right radius at a glance. The working area is protected by the large drill disc. Sufficiently large openings reliably remove dust during rotation and prevent it from getting stuck in the drill body. This ensures that the function of the setting mechanism is permanently guaranteed despite intensive dust formation.
