Gatzaag ToughMaterial Starter Kit

Long Life and Fast Changing! Individually ground teeth made from fine, hard carbide. Most hole saws for wood and metal seem to work fine - until you hit a hardened nail or screw. Then they scream and smoke and grind until their teeth are torn off, and you still only have half a hole. With its carbide teeth, the EXPERT Tough Material barely slows down when it hits metal – it cuts neatly through and keeps on cutting holes, time and again. The Bosch EXPERT Tough Material Hole Saw great all-rounder for every tradesman – because half a hole is not even worth half a hole. Exceptional durability is built in with Bosch Carbide Technology.
