5-piece ULTIMATECUT cone/deburring countersink set DIN 335 90°, dia. 6.3 - 10.4 - 16.5 - 20.5 - 25.0 mm

FAST. SHARP. STRONG. SENSATIONAL.

High quality work, lower costs. The newly developed ULTIMATECUT 4S countersink works with four instead of three cutting edges. The distribution of the forces acting on the four cutting edges noticeably reduces the axial and radial forces and guarantees extremely smooth and material-friendly operation of the tool thanks to the uneven distribution.

The new ULTIMATECUT 4S countersink not only ensures a perfect countersink pattern without chatter marks, but also particularly energy-efficient and material-friendly working with up to a 50% time saving and up to a three times longer service life for the tools used.
