Top Cut 4 has a breadth of application capabilities that include through and cross-holes, and inclined entry and exit holes. The drills can also complete 45° corner, half-cylindrical, concave and chain drilling operations. Featuring four true cutting edges that combine with Widia grade technology, higher speeds and feeds and, subsequently, metal-removal rates can be achieved, says the company, which cites tool life as a further advantage.
Discussing the Top Cut 4, Widia product manager Vivian Pavlov, says: “Process stability is a significant challenge and was the driver behind Top Cut 4 and its development. Process stability is the ability to quickly select and successfully apply a tool, even in an unfamiliar or unstable condition. Users need one drill that can be applied in a variety of drilling operations and workpiece materials.”
Top Cut 4’s periphery and centre inserts feature proprietary cutting profiles for good centring capability and workpiece penetration. The inserts are clearly differentiated to eliminate operator confusion, and are available in grades for high-speed applications, tough material demands and high metal removal rates. Specific geometries are can be selected with reinforced cutting edges and a steep chip breaker for steel, cast iron and short-chipping materials. ITC can also offer inserts with an optimised chip groove for stainless steel, long-chipping steels and machining applications where low power consumption is required.
Widia’s Top Cut 4 features stable tool shanks in lengths of 2xD, 3xD, 4xD and 5xD, in both metric and imperial dimensions, with diameter ranges from 12 to 68 mm. There are eight insert sizes that cover the complete diameter range. The cutter bodies incorporate high helix angled flutes for optimised chip evacuation, even at 5xD, says the company. Furthermore, large coolant holes mean efficient coolant delivery and extended insert life.
The Top Cut 4 platform is available through Widia’s NOVO digital process knowledge application.
