Welcome to the world's first.
04 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.
130° max 10,0 mm HSS 4 90° ULTIMATECUT Step drills HSS RUnaTEC, spiral fluted with turbo tip Ø2 Ø1 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.

Effective without compromises. 04 The new RUKO step drill generation • Up to 4 times more holes • Smooth and quiet drilling • Significantly improved drilling result Upgraded and Improved Product. Improved specification replaces previous version.
04 FlowStep Technology Information and videos Improved control on more difficult to cut materials, such as thin sheet and Plexiglas, whilst still providing outstanding performance on tougher materials such as stainless steel. Unique new cutting geometry design provides an easy, low force, seamless transition between the increasing hole diameters.
118° 2 90° Ø2 max 4,0 mm Ø1 Step drills HSS and HSSE-Co 5, spiral fluted with split point The CBN ground and spiral flutes guarantee quiet running and high cutting performance. Especially the chip flow is optimized, so even long, non-breaking chips will be removed easily. The optimized chip flow protects the cutting edges and reduces built-up edges and cold weld marks. The chamfer on the base of the cone makes withdrawal of the tool from the material simple when through hole drilling.

The reduced load of the cutting edges allows a higher feed rate especially for soft materials like non-ferrous metals. The chamfer on the base of the cone makes withdrawal of the tool from the material simple when through hole drilling.
