Rigid and compact turning tools

Engineered with an interface repeatability within ±2µm for the insert carrying cassette, this enables inserts to be quickly and easily changed outside of the machining zone with highly accurate relocation within the toolholder.

The GND-Series ISO Polygon Cassette Grooving System expands the original Sumitomo GND grooving system launched in 2012 and in 2014 the extended range introduced a polygon monoblock shank toolholder series. This addition accommodated turning, copying and facing applications involving positive and negative inserts.

Maintaining the same ultra-rigid, self-guiding coupling design of the polygon monoblock holder providing quick and easy setting, the GND-Series ISO cassette grooving system introduces both PSC straight and L-style holders for external grooving applications. These cover groove widths from between 2mm by up to 12mm deep to 6mm by 18mm in depth.

There is a series of external left and right hand multi-purpose cassettes GNDCMR and GNDCML for profiling or turning wide grooves and seven chipbreaker-style coated carbide inserts. These have been specially developed to provide excellent chip control across applications involving carbon and alloy steels, stainless steels, cast iron and exotic alloys.

Inserts enable higher performance to be achieved when general machining plus being ideal for applications where the use of lower feed rates or low cutting forces are involved. There is also a special dedicated GF insert for part-off and a RG insert for general profiling applications.
