RUKO Countersink 4S HSS-Co5 RUnaTEC UltimateCut
The new ULTIMATECUT 4S countersink features four cutting edges instead of three. Distributing the forces across four edges significantly reduces axial and radial forces and ensures exceptionally smooth, material-friendly operation thanks to the uneven pitch. ULTIMATECUT 4S provides vibration-free performance and a clean countersunk surface, while enabling energy-efficient, material-saving work. The result is up to 50% faster machining and up to three times longer service life. As an additional benefit, the new cutting technology allows countersinking up to 40 mm in diameter even with handheld screwdriving and drilling tools. The tool comes standard with a three-flat shank that prevents slipping in the drill chuck and ensures consistent power transmission during operation.
RUnaTEC coating:
Even greater wear resistance and more efficient material removal. The RUnaTEC coating developed by RUKO guarantees high performance. Especially in demanding materials such as heat-treated steel, the coating provides effective penetration and excellent wear resistance.
