Since 1974 we specialize in the production of drilling, countersinking, and cutting tools. The high-quality precision tools from our production facility in Germany provide high-performance tools for the professional user in industry and trade. We are your reliable partner in the field of metal cutting. Our drive is our fascination.


Step Drill

Completely renewed, the new RUKO step drill generation impresses with its uncompromising effectiveness. Improved control on more difficult to cut materials, such as thin sheet and Plexiglas, whilst still providing outstanding performance on tougher materials such as stainless steel. Unique new cutting geometry design provides an easy, low force, seamless transition between the increasing hole diameters. Faster and higher service life than ever thanks to the new point cut, the specially developed chip space geometry and the optimization of the helix angle. Versatile in its application, Plexiglas and wood can also be easily cut in addition to materials like steel and stainless steel, with the best drilling results at the same time.

The newly developed cutting geometry of the ULTIMATECUT by RUKO enormously reduces the axial and radial forces, which are affecting the tool during the countersinking.. The variably running relief grinding was specially developed and ensures a very quiet countersinking procedure and a perfect surface quality, which guarantees the best results. The specially developed flute parameters, such as the angle, the transition radius as well as the extra-wide chip flute, ensure an optimal chip and heat removal and therefore enable a high wear resistance. Furthermore, the new geometry prevents material welding and reduces the countersinking force. Considerably less feed power while countersinking is now necessary. The materials can be handled either with a very high as well as with a very low cutting speed, without loss of quality/loosing quality concerning the result.
