Ruko ULTIMATECUT countersink 4S HSSE-Co 5 DIN 355 90°

Can do it better. Can do it faster. Can do it longer. The Ultimatecut conical countersink 4S in HSSE-Co5 offers a longer tool life for quicker results. The newly developed Ultimatecut conical countersink 4S operates with four cutting edges instead of three. The distribution of forces across the four cutting 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 conical countersink 4S not only provides a perfect countersink appearance without chatter marks but also allows for particularly energy-efficient and material-friendly 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 allows for countersinking with a diameter of up to 40 mm using handheld screw and drilling tools. The new Ultimatecut conical countersink 4S works equally precisely in pillar drilling machines as well as in CNC-controlled machining centers. The new Ultimatecut conical countersink 4S comes standard with a 3-flat shank, which prevents slipping in the drill chuck and ensures consistently optimal power transmission during the working process.
