Applications
This indexable drill insert is primarily suited for modern U-drill systems and supports efficient hole creation in workpieces made of steel and stainless steel. Thanks to its adaptable carbide grade, it serves as an excellent choice for both single-part and series manufacturing in machining facilities where consistent tool performance and smooth workflows are the focus.
Special features
The well-conceived design of the SPMG insert allows the utilization of four cutting edges, which optimizes tooling costs during drilling operations. The combination of tough carbide and a smooth PVD layer provides good resistance against wear and supports organized chip evacuation. With its precise execution, the product ensures reliable dimensional accuracy for boreholes of various diameters.
