Bosch Professional Zubehör PRO Multi Material PC Plus hole saw, 21 mm

Lasts up to 2x longer than a standard HSS M3 hole saw. For electricians and plumbers, hole saws are invaluable for installing pipes, junction boxes, and recessed lights. Ideally, you want just one type of hole saw for all the challenges and materials that interior construction presents. The solution: the PRO Multi Material. The PRO Multi Material hole saw features an improved tooth design for fast and smooth cuts. Its high-cobalt HSS alloy ensures durability. It is particularly suitable for steel cladding and drywall. With the Power Change plus adapter, hole saws and pilot drills can be changed more quickly, and core removals are easier. Designed for use with Bosch's Power Change Plus quick-change adapter: for precision and robustness.
