Milling from a different angle

Dormer Pramet introduced a versatile new line of tools and inserts to support economical shoulder milling applications in a wide variety of materials. The TNGX10 double-sided triangular inserts – launched under our Pramet brand – offers depth of cut up to 5mm and feature six cutting edges for excellent economy and low machining costs.


A wide range of cutters are available with the new assortment, from 18mm up to 80mm, and with a high number of teeth available – even for small diameters – the cutters provide increased productivity. The inserts are suitable for numerous materials such as steel, stainless steel, cast iron and non-ferrous metals, as well different applications, including shoulder, face and slot milling, helical interpolation, ramping and progressive plunging.


In a recent product test, face milling M3 stainless steel, the TNGX insert had double the durability, compared to a competitor’s equivalent insert. To support the new shoulder milling range, three new positive geometries have also been launched.


Geometry F has a narrow peripheral land and is suited to light and medium machining for low to medium carbon steel. Geometry M with a medium T-land is also suitable for light and medium machining, but for carbon steel and stainless steels. Finally, geometry FA has a sharp cutting edge and is particularly for machining non-ferrous metals. Its polished insert face reduces sticking of the machined material, promoting longer tool life and better workpiece finish quality.
