Step by step to excellence.
Now also available in HSSE-Co 5 for machining stainless steel.
The RUKO ULTIMATECUT Step drill with FLOWSTEP® tip
- Drills longer. For extra-long service life.
- Perfect centering. Precise drilling without drifting for precision from the very first cut.
- No tool changes. For uninterrupted drilling.
The addition of the HSSE-Co 5 variant now also enables the machining of the most demanding materials such as stainless steel.
The FLOWSTEP® tip
The FLOWSTEP® tip enables precise centering without center punching and faster drilling on different materials and surfaces, such as pipes. Pre-drilling with smaller diameters is completely eliminated, as are time-consuming tool changes. In addition, the FLOWSTEP® tip significantly reduces strain, enabling sustained, fatigue-free work.
The FLOWSTEP® technology
The 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. FLOWSTEP® technology ensures noticeably effortless operation.
The difference you can feel: refinement at the highest level
RUKO's proprietary RUnaTEC coating guarantees ideal heat dissipation and thus an extra-long tool life. It enables even simpler and less strenuous machining, which is truly 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.
