ULTIMATECUT taper and deburring countersink set 4S HSS RUnaTEC DIN 335 90° in plastic case 6 pieces Ruko

FAST. SHARP. STRONG. SENSATIONAL.

Work quality up, costs down. The newly developed ULTIMATECUT countersink 4S works with four cutting edges instead of three. The distribution of the forces acting on the four cutting edges noticeably reduces the axial and radial forces and guarantees extremely smooth and gentle running of the tool thanks to the unequal distribution.

The new ULTIMATECUT countersink 4S therefore not only ensures a perfect countersinking pattern without chatter marks, but also particularly energy-saving and material-friendly working with up to 50 % time savings and up to 3 times longer tool life.

Another plus: for the first time, the newly developed cutting technology can even be used for countersinks with diameters up to max. 40 mm with hand-held screwing and drilling tools.

The new ULTIMATECUT countersink 4S works just as precisely in pillar drills as it does in CNC-controlled machining centers.

The new ULTIMATECUT countersink 4S has a 3-face shank as standard, which prevents it from slipping in the drill chuck and ensures consistently optimum power transmission during the work process.

RUnaTEC
Even more wear-resistant, even more biting when removing material. The RUnaTEC coating developed by RUKO guarantees even higher performance. The coated RUnaTEC variant is particularly impressive when it comes to demanding materials such as tempered steel, thanks to its powerful penetration into the material and even better wear resistance.
