ULTIMATECUT

Metal cutting in a new dimension.

The ULTIMATECUT step drill revolutionizes the work process and sets new standards in machining time with time savings of up to 75%. The step drill from RUKO achieves this through its revolutionary cutting edge geometry by combining the most diverse applications and tools. This means less tools needed, no tool changes and ultimate flexibility.

Unique in every step.

No center punching thanks to specially developed turbo tip.

No tool changes due to pre-drilling and different drill hole diameters, which would occur with for e.g. twist drills.

No problems in hard-to-reach places, for e.g. T-beams, where the use of big machines with core drills is problematic.

No problems with low holding forces of magnetic stand drilling machines for materials < 10 mm, since it can be drilled with a manual drilling machine.

No extra deburring necessary, the next step takes over this function.
