With 7 quick-change blades with Ø 25, 32, 38, 45, 50, 56 and 62 mm and a cutting depth of 23 mm, the multi-blade hole saw offers you flexible equipment for a wide range of interior works projects. With the saw blades made from hardened and tempered strip steel, it is ideal for wood and drywall materials (e.g. plasterboard and OSB panels). The hexagon shank makes it compatible with all commercially available cordless screwdrivers and power drills. A Ø-8-mm centring drill bit helps you to position your drilled hole exactly. The multi-blade hole saw has a safety lock to reliably fix the conduit hole saw in the drill plate. This is especially important for good working safety when using cordless screwdrivers with a fast rotation stop mechanism. To enable you to get going straight away, the hole saw comes pre-assembled. The multi-blade hole saw is TÜV-tested, meaning you can be sure of a safe, quality product.
