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

With easily machinable materials, the variable tooth design ensures a more even cut and reduced effort. The lower vibration and heat generation during cutting result in up to three times longer service life. They are 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.
