Ruko UC COUNTERSINK SET 4S HSS, 90° 12.4 MM 3FL. 102876

High work quality, low costs. 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 uneven distribution. As a result, the new ULTIMATECUT countersink 4S 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 edge technology can even be used to countersink holes with a maximum diameter of 40 mm with hand-held screwing and drilling tools, and the new ULTIMATECUT countersink 4S works just as precisely in pillar drills as it does in CNC-controlled machining centres.The new ULTIMATECUT countersink 4S has a 3-face shank as standard, which prevents slipping in the drill chuck and ensures consistently optimum power transmission in the work process.
