The RUKO tungsten-carbide multigrade hole saws MHS can be used in magnetic and standard drills for a maximum of 20.0 mm in steel and for hand drills up to 6.0 mm in steel. They are suitable for high-alloyed steels such as stainless and acid-resistant steel, as well as steel and cast steel (up to 20.0 mm), non-ferrous and light metals, and plastics (up to 28.0 mm). Applications include drilling flat materials, tubes, and vaulted surfaces, with overlapped holes possible.

The Ø 15.0 up to 30.0 mm hole saw MHS and shank are in one piece, complete with a pilot pin and wrench. The Ø 31.0 up to 100.0 mm hole saws MHS are available without an arbor. For sizes Ø 65.0 up to 100.0 mm, we recommend using our Morse taper holder.
