The hole saw made of hardened and tempered steel strip with a diameter of 65 mm and a cutting depth of 33 mm is ideal for setting cavity wall boxes in wood and drywall materials (e.g. plasterboard and OSB boards). The hexagonal shank makes it compatible with all commercially available cordless screwdrivers and drills. A Ø 8 mm centre drill makes it easier for you to position your drill hole precisely. The sturdy aluminium mounting plate ensures a long service life. It is pre-assembled so that you can get started straight away.
