Icon of a new performance class

More process reliability: The new drills are internally cooled. Thanks to shallow grooves, the coolant flows unimpeded, while hazardous chip jams are at the same time avoided. Because of the new design of the lands, the liquid washes around the drill continuously, producing a unique cooling effect.

Longer tool life: The solid carbide mass directly behind the cutting edge makes the DC170 incredibly sturdy. Even extreme temperatures are effectively dissipated.

Higher hole quality: An effect of the new type of alignment of the lands is significantly smoother drill running. Because they are continuously guided, vibration is reduced to a minimum, and so the DC170 wins favour across the board.

Less expensive manufacturing: The distinctive cooling channels ensure the optimum operating temperature. Drills straight from the factory are supplied with eight visible channels that can be used as a scale for regrinding.

The DC170 drills can be reconditioned up to three times, until only two cooling channels are left remaining. Users who make full use of this nowvisible regrinding potential can lower their manufacturing costs.​
