With 5 quick-change inserts in diameters of 68, 74, 80, 90 and 100 mm and a cutting depth of 33 mm, the electrical installation hole saw offers you flexible equipment for preparing electrical installations (e.g. sockets, recessed spotlights). It is ideal for wood and drywall (e.g. plasterboard, OSB). The hexagonal shank makes it compatible with all commercially available cordless screwdrivers and drills. A centring drill (Ø 10 mm) makes it easier for you to position your hole precisely. The multi-rip hole saw has a safety lock that reliably secures the drill collars in the drill disc. This is particularly important for high work safety when using cordless screwdrivers with a fast rotation stop.
