Ruko ULTIMATECUT 4S 102890PRO Countersink set 6-piece 6.30 mm, 8.30 mm, 10.40 mm, 12.40 mm, 16.50 m

6-piece UltimateCut Countersink Set DIN 335 90° Ø 6.3 - 8.3 - 10.4 - 12.4 - 16.5 - 20.5 mm. High working quality, lower costs. The newly developed UltimateCut 4S countersink works with four cutting edges instead of three. The distribution of forces across the four edges significantly reduces axial and radial forces, ensuring an extremely smooth and material-friendly operation of the tool due to the unequal division. This means that the new UltimateCut 4S countersink not only provides a perfect countersink appearance without chatter marks but also allows for particularly energy-efficient and material-saving work, achieving up to 50% time savings and up to three times longer tool life. Another advantage: For the first time, the newly developed cutting edge technology enables countersinks with diameters of up to 40 mm to be performed with handheld screw and drilling tools. The new UltimateCut 4S countersink operates equally precisely in pillar drilling machines and CNC-controlled machining centers. The new UltimateCut 4S countersink comes standard with a 3-flat shank that prevents slipping in the drill chuck and ensures consistently optimal power transmission during the working process. RUnaTEC: Even more wear-resistant, even more aggressive in material removal. The RUnaTEC coating, developed by RUKO, guarantees even higher performance. Especially with demanding materials, such as alloyed steel, the coated RUnaTEC variant impresses with powerful penetration into the material and significantly improved wear resistance.
