ULTIMATECUT

New dimension in performance.

Thanks to the revolutionary FLOWSTEP® tip, precise centering and faster spot drilling are possible on a wide range of materials. The specially developed unique cutting edge geometry leads to a much smoother and quieter drilling process due to its smooth step transitions, which significantly reduces the processing time and improves the drilling result considerably.

Even more precise with each step.

Precise centering without center punching even on round surfaces such as pipes.

Extremely fast and force-saving tapping.

Smooth and quiet drilling process, without jamming in the material.

Better and cleaner work result.

Guaranteed durability and speed due to in-house RUKO nano Technology coating, in short RUnaTEC.
