With these adjustable hole saws, you can create all hole diameters from 45 to 90 mm and 45 to 130 mm. You only need one product for many diameters! The three triple-tooth groups cut effortlessly through drywall and softwood panels, ensuring fine and clean cuts with their specially designed staggered teeth. Adjusting the size is done in three simple steps: loosening, synchronizing, and fixing. The integrated millimeter scale, along with additional scales for common installation diameters, helps you find the correct radius at a glance. The large drill plate protects the work area. Sufficiently large openings reliably channel dust away during rotation and prevent it from getting stuck in the drill body. This ensures the functionality of the adjustment mechanism remains intact despite intense dust generation.
