Bosch Professional Zubehör EXPERT Tough Material hole saw set, 22/25/35/40/51/68 mm, 9 pcs.

Lasts up to 50 times longer than a bi-metal hole saw in tough materials - Most hole saws for wood and metal seem to work fine - until you hit a hardened nail or screw. One quick jerk and now you're missing a few teeth. With its carbide teeth, the Expert Tough Material hardly slows down when it hits metal. It penetrates the material cleanly and cuts it reliably. Each tooth made with Bosch Carbide Technology has optimum quality of the hardest metal. It is laser welded and ground six times to achieve the perfect cutting shape. This makes the Bosch Expert Tough Material hole saw ideal for heavy-duty tasks and all-round work: In addition to wood and metal, the hole saw can also be used well for stainless steel, brick, soft tiles and reinforced plastics. The Bosch Expert Tough Material hole saw is an excellent all-rounder for every craftsman - because nobody can use only half a hole. For use with the Power Change Plus quick-action adapter from Bosch: for accuracy and robustness.
