Lasts up to 50x longer than a BiMetal hole saw in tough materials. 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. 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 Tough Material 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 Tough Material Hole Saw great all-rounder for every tradesman - because half a hole is not even worth half a hole. For use with the Bosch Power Change Plus keyless arbor: offering accuracy and robustness.
