The RUKO ULTIMATECUT step drill with FLOWSTEP® tip
Innovation through FLOWSTEP® tip
- 6x more holes possible
- Up to 75% faster spot drilling
- Perfect centering
The so-called FLOWSTEP® tip impresses with its performance and makes it unique in terms of speed, ease of movement and drilling results.
The 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® technology
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.
RUKO nano Technology - up to 16 times longer service life and optimised, smooth countersink surface
RUKO's RUnaTEC coating represents a significant advance in tool technology by offering an unrivalled combination of wear resistance, hardness and performance. This specially developed coating has been designed to significantly increase the life and efficiency of cutting tools, making it a valuable innovation for a wide range of cutting applications.
Extremely high wear resistance
The RUnaTEC coating is characterised by its extremely high wear resistance. This is achieved through the application of advanced coating technologies that form a dense, uniform layer that effectively protects the surface of the tool from wear. This property is particularly advantageous when machining hard or abrasive materials, where conventional uncoated tools would wear out quickly.
Increased heat hardness
Another outstanding advantage of the RUnaTEC coating is its increased hot hardness. Tools with this coating retain their cutting edge integrity even at high machining temperatures, which typically occur during intensive cutting processes. This enables consistently high tool performance over a wide temperature range and reduces the risk of tool failure due to overheating.
No material welding
The RUnaTEC coating effectively prevents material welding, a common challenge when machining sticky or soft materials. By minimising adhesion between the workpiece and tool, the coating improves the surface quality of the machined parts and simplifies chip removal, resulting in a smoother surface.
Optimum, smooth surfaces
By reducing friction between the tool and the workpiece, the RUnaTEC coating enables the creation of optimised, smooth surfaces. This improved surface quality is not only aesthetically pleasing, but can also increase the functionality of components, for example by improving fatigue resistance.
Extremely high nano-hardness
The exceptional nano-hardness of the RUnaTEC coating contributes significantly to the overall performance of the coated tools. This nano-hardness leads to a further increase in wear resistance and enables the tools to deliver precise cuts even under difficult conditions.
