The fine toothing is particularly suitable for cutting metals. It ensures smoother running and reduces the necessary effort. The reduction in heat development during cutting increases tool life, especially in the case of metals. Suitable for alloyed and non-alloyed steels (up to 1.000 N/mm² strength), high chromium alloyed steels such as stainless steel, steels resistant to rusts and acids, non-ferrous and light metals.

Bi-metal hole saws can be used in hand and pillar drills.

When employing pillar drills, use manual advance only.
