True 90° shoulder milling solution

Dormer Pramet has expanded its offer for true 90° shoulder milling in various materials.

With improved cost per edge, the company’s new range of TNGX16 inserts and STN16 cutters feature larger double-sided inserts with six-cutting edges, providing greater depths of cut (up to 10 mm) and higher feed compared with its existing TNGX10 range.

By offering low cutting resistance, the assortment improves the connection between passes, creating high surface quality. This reduction in forces leads to smooth, quiet machining for additional process security.

Positive geometry and through-coolant offer improved chip evacuation across a range of materials, including steels, stainless steels, cast iron and non-ferrous metals.

Dormer Pramet’s TNGX16 assortment is available in radii from 0.4 to 1.6 mm and in a range of grades. Three geometries, F, M and FA, support the insert. F is the first choice for low to medium carbon content steel. A high positive geometry with narrow peripheral land makes F geometry suitable for light to medium machining.

M geometry is for machining carbon steel, stainless steel and cast iron. This positive geometry with medium T-land makes it suitable for light to medium machining.

For use on non-ferrous metals, FA is a high positive geometry with a sharp cutting edge. The polished insert face reduces adhesion to machined material.

Meanwhile, STN16 tool holders provide a higher number of teeth for greater productivity in comparison with the original assortment. The differential pitch offers smooth machining in diameters above 50 mm.
