Does it better. Does it faster. Does it longer. They used to be called nerds.
The innovative countersink 4S is now also available in HSSE-Co 5 version.
The new countersink 4S HSSE-Co 5
- with special strengths for high-performance machining of demanding Hardox steels
- best performance in stationary + manual use
- significantly less feed force required
- up to 3x more countersinking possible
- up to 50% faster sinking
- extremely smooth running
- optimum countersink pattern without chatter marks
Four cutting edges for maximum performance and limitless efficiency
With its specially developed four cutting edges and unequal spacing, the HSS version of the ULTIMATECUT countersink 4S already guarantees optimum countersinking results in both stationary and manual use, with significant time savings.
The distribution of forces across the four cutting edges reduces the axial and radial forces, which protects the tool and significantly increases tool life.
With the addition of the HSSE-Co5 variant, the range of applications for the ULTIMATECUT 4 S series has been further extended with the possibilities for professional machining of stainless steels and demanding Hardox steels.
Countersink 4S: Left with coating, right without coating.
Optimum countersink pattern
Even experienced craftsmen can suffer from chatter marks, unevenness or uneven countersinks. With the ULTIMATECUT countersink 4S, however, this is a thing of the past.
The special design of the tool makes it possible to achieve flawless countersinks with exceptional precision. The unequal pitch ensures that the countersink glides through the material and leaves a round countersink without chatter marks.
This technology significantly reduces vibration during the countersinking process, resulting in improved surface quality. The precise design of the cutting edge geometry of the ULTIMATECUT countersink 4S enables even chip removal, which in turn minimises heat generation and reduces the risk of material deformation.
"Our ULTIMATECUT product line stands for the highest precision and quality in the tool industry. The introduction of the HSSE version of our ULTIMATECUT countersink 4S emphasises our commitment to continuous improvement and the development of innovative solutions. This countersink adds improved performance and efficiency to the proven strengths of the HSS model without diminishing the qualities of HSS, but rather increasing the application possibilities for our users."

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.
