This accessory proved to be a game-changer in my industrial and scientific work. The cutting is incredibly quick and clean with no burrs left behind. It is suitable for a range of fiberboard thicknesses and sizes, making it a versatile tool. However, it can be slightly tricky to maintain the precision of the hole in thicker fiberboard due to the blades slight wandering .Overall, I am impressed with this tool's performance and can't imagine going back to the conventional saws..
