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 Multi Material PC Plus barely slows down when it hits metal – it cuts neatly through and keeps on cutting holes, time and again.
Made with Bosch Carbide Technology, each tooth is an optimum grade of the hardest metal, laser welded and ground six times for the perfect cutting shape. This makes the Bosch EXPERT Multi Material PC Plus Hole Saw ideal for tough jobs and all-round trades work: As well as wood and metal, it’s a good hole saw for stainless steel, brick, soft tiles and reinforced plastics.
The Bosch EXPERT Multi Material PC Plus Hole Saw great all-rounder for every professional – because half a hole is not even worth half a hole.
