Most wood and metal hole saws seem to work well until you hit a hardened nail or screw. Then they screech, smoke, and saw until their teeth come off, and you still only have half a hole. The carbide-toothed EXPERT Tough Material barely slows down when it touches metal, it cuts cleanly through and continues cutting holes.
Each tooth, made using Bosch Carbide Technology, is perfectly cut, made from the hardest metal, laser-welded, and polished six times. This makes the Bosch EXPERT Tough Material hole saw ideal for heavy and versatile jobs: In addition to wood and metal, it is also a good hole saw for stainless steel, bricks, soft tiles, and reinforced plastics.
The Bosch EXPERT Tough Material hole saw is a great universal tool for every worker, because half a hole is not even worth half a hole.
