New grades and chipbreakers have been added to the already established GND grooving system with polygon shank and a flexible and economical cassette system for inserts. An array of chipbreakers improves the efficiency in chip control in various applications such as grooving, turning, profiling and cut-off.

Thanks to our new modular grooving system, cassettes for TGA inserts have been added to the modular system for soft grooving. Triangular TGA inserts with integral chipbreakers achieve outstanding chip control. Combined with AC530U grade TGA inserts cover a wide application range for machining of steel, stainless steel and cast iron.

In addition to GND and TGA inserts for soft grooving, tangential CGA inserts enable hard grooving with SUMIBORON grades. Uncoated CBN grade BN250 developed for continuous grooving and coated CBN grade BNC30G for interrupted grooving applications.
