WIDIA indexable holemaking platform

Latrobe, Pennsylvania – Expanded capabilities and improved performance combine for outstanding results in the new Top Cut 4 indexable holemaking platform. A multi-problem-solver in one platform, Top Cut 4 is targeted to end users that need one drill that can be applied in a variety of drilling applications and different workpiece materials.

Top Cut 4´s breadth of application capabilities include through- and cross-holes, inclined entry and exit opportunity, 45° corner, half-cylindrical, concave, and chain drilling. And four true cutting edges result in notably higher speeds and feeds, higher metal-removal rates, and extended tool life.

Top Cut 4 periphery and center inserts each feature proprietary cutting profiles for excellent centering capability and workpiece penetration. The inner and outer (center and periphery) inserts are clearly differentiated for no mixups, and are available in grades for high-speed applications, high toughness demands, and high metal-removal rates in general.

Specific geometries are available with such features as reinforced cutting edges and a steep chipbreaker for steel, cast iron, and short-chipping materials, or an optimized chip groove for stainless steel, long-chipping steels, and where low power consumption is required.

In addition, Top Cut 4 is featuring high-stability shanks in lengths of 2XD, 3XD, 4XD, and 5XD, in both metric and inch configurations. Diameter ranges from 12mm to 68mm (0.473” to 2.5”). 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.
