world's first.
The new RUKO
step drill
5 in 1 tool
Up to 75% time savings
Ultimate flexibility
Unique in every step.
No center punching thanks to specially developed turbo tip.
No tool changesdue 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.
