Holemaking Platform


A true multi-problem solver in one platform, the Top Cut 4 indexable holemaking platform is targeted to end users that need one drill that can be applied to a variety of drilling applications and different workpiece materials. Its breadth of application capabilities includes through- and cross-holes, inclined entry and exit opportunity, 45-deg corner, half-cylindrical, concave, and chain drilling. Four true cutting edges combined with WIDIA-grade technology result in notably higher speeds and feeds, higher metal-removal rates, and extended tool life. Top Cut 4 features high-stability shanks in lengths of 2XD, 3XD, 4XD, and 5XD, in both metric and inch configurations.

Diameter ranges from 12 to 68 mm (0.473 to 2.5 inches). Eight insert sizes cover the complete diameter range. The cutting edge profile of the central and periphery inserts works together, leading to high stabilization of the drill, preventing tool drifting even on irregular surfaces.

Robust cutter bodies are marked by deep helix angled flutes for efficient chip evacuation even at 5XD length. Large coolant holes mean efficient coolant delivery and extended insert life.

Moreover, Top Cut 4 is available through NOVOTM, WIDIA´s digital process knowledge application. With powerful process knowledge available on iPadTM and other digital devices, NOVO provides far more useful process knowledge than any online catalog alone, all obtained in a fraction of the time.
