The RUKO ULTIMATECUT Step drill with FLOWSTEP® tip

Precise centring without centre punching and faster drilling on different materials and surfaces such as pipes. The FLOWSTEP® tip guarantees an easy and smooth drilling process without jamming in the material. This tip also saves time when drilling, as fast and easy drilling is possible without much effort. The twist drill also has the advantage that it is no longer necessary to pre-drill with small drill bits, especially for large drill diameters. This completely eliminates the need to change tools, which also saves a lot of time and tools.

The FLOWSTEP® tip gets its name from the FLOWSTEP® technology developed by RUKO. This specially developed, unique cutting edge geometry leads to a much smoother and quieter drilling process thanks to its gentle step transitions, which significantly reduces the machining time and considerably improves the drilling result. Another guarantee for durability and speed is the proprietary RUKO nano Technology coating, RUnaTEC for short. Thanks to the three-surface shank, the tools are also ideally suited for use in hand-held drills.

Our ULTIMATECUT Premium line guarantees a doubling of tool life due to the RUKO-own RUnaTEC-coating Aa doubling of tool life and even simpler and more energy-saving machining of even demanding materials, which is actually noticeable.

The RUnaTEC-coating has an extremely high wear resistance and nano-hardness, increased hot hardness, does not result in material welding and achieves an optimum, smooth surface.
