Ruko Bimetal hole saws HSS variable teeth

The RUKO bi-metal hole saws can be used in hand and pillar drilling machines. For pillar drilling machines, please use only manual feed.

With easily machinable materials, the variable tooth design ensures a more uniform cut and reduced effort. The lower vibration and heat generation during cutting result in up to three times longer tool life. Suitable for unalloyed steel (up to 700 N/mm² strength), non-ferrous and light metals, plastics, gypsum, lightweight construction, fiber, plywood panels, and wood processing.
