Does it better. Does it faster. Does it longer. The ULTIMATECUT Countersink 4S in HSSE-Co5 with even longer tool life for even faster work results. The newly developed ULTIMATECUT countersink 4S works with four instead of three cutting edges. The distribution of the forces acting on the four cutting edges noticeably reduces the axial and radial forces and guarantees extremely smooth and material-friendly running of the tool through the unequal division. The new ULTIMATECUT countersink 4S thus not only ensures a perfect countersinking pattern without chatter marks, but also particularly energy-saving and material-saving work with up to 50%-time savings and up to 3 times longer tool life. Another plus: For the first time, countersinking with diameters up to max. 40 mm can even be carried out with hand-held screwing and drilling tools using the newly developed cutting-edge technology. The new ULTIMATECUT countersink 4S works equally precisely in pillar drilling machines as well as in CNC-controlled machining centers. The new ULTIMATECUT countersink 4S has a 3-surface shank as standard, which prevents slipping in the drill chuck and ensures a consistently optimal power transmission in the work process. RUnaTEC Even more wear-resistant, even more biting material removal. The RUnaTEC coating developed in-house by RUKO guarantees even higher performance. Particularly with demanding materials, such as heat-treated steel, the coated RUnaTEC version convinces with powerful penetration into the material and even better wear resistance.
