This adjustable hole saw lets you drill all holes from 45-90 and 45-130 mm. You only need one product for many diameters! The three triple tooth blades saw through plasterboard and softwood boards with ease, and ensure fine and clean cuts with their special, straight-set toothing. The size is set in three simple steps: loosen, adjust synchronously, and fasten. The integrated millimetre scale as well as further scales for standard installation diameters help you to find the right radius at a glance. The large drill disc protects the work area. Sufficiently large openings reliably remove the dust during rotation and stop it getting stuck in the drill body. This ensures the function of the positioning mechanism in the long term despite the formation of large quantities of dust.
