BOSCH PRO Sheet Metal PC Plus Hole Saw, 21 mm

Lasts up to 2x longer than a standard HSS M3 Hole Saw - When you cut sheet metal you want a hole saw that is tough enough to cope with hard steel and still able to make neat and efficient cuts for pipes. The PRO Sheet Metal ticks all these boxes and is a firm favourite with professional metalworkers. We made the PRO Sheet Metal Hole Saw for professionals who need to cut metal. Its teeth are made from HSS with 8% cobalt, which makes them sharp and durable. It has a hardwearing body and a handy ejection spring helping you remove material plugs with ease. For use with the Bosch Power Change Plus keyless arbor: offering accuracy and robustness
