ULTIMATECUT

More precise. More powerful. Faster.

The ULTIMATECUT countersink is a high performance tool which stands for best performance: up to 30% time savings, twice as many countersinks as standard tools and excellent, smooth countersinking results in almost all materials.

The specially developed countersink from RUKO achieves this through its unique cutting edge geometry, with the specially developed variably running relief grinding, transition radius and the extra-wide chip flute.

ULTIMATECUT Countersink

1.
REVOLUTIONARY FLUTE GEOMETRY

The specially developed flute parameters, such as the angle, the transition radius as well as the extra-wide chip flute, ensure an optimal chip and heat removal and therefore enabale a high wear resistance. Furthermore, the new geometry prevents material welding and reduces the countersinking force.

2.
OPTIMIZED RELIEF GRINDING

The variably running relief grinding was specially developed and ensures a very quiet countersinking procedure and a perfect surface quality, which guarantees the best results. (The new RUnaTEC coating increases the quality additionally)

3.
3-SURFACE SHANK

Prevents slipping in the chuck and makes the countersinker perfectly suitable for the application in hand drilling machines.
