Delivering true 90° shoulder milling with new TNGX

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

With improved cost per edge, the global manufacturer has introduced a new range of TNGX16 inserts and STN16 cutters. The larger double-sided inserts have six-cutting edges, providing greater depths of cut (up to 10mm) and higher feed compared to its existing TNGX10 range.

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

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

The TNGX16 assortment is available in radii from 0.4mm to 1.6mm and alongside a wide range of grades. It is supported by three geometries, F, M and FA. F is the first choice for low to medium carbon content steel. A high positive geometry with narrow peripheral land makes it suitable for light to medium machining.

The M geometry is for machining carbon steel, stainless steel and cast iron. Its positive geometry with medium T-land, makes it ideal for light to medium machining. Suitable for non-ferrous metals, FA is a high positive geometry with a sharp cutting edge. Its polished insert face reduces sticking of machined material.

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

Manufactured from coated tool steel for better resistance against corrosion and reduce friction, the cutter features large and strong clamping screws for easier handling and stability. A precision machined pocket design enables performance repeatability and security.
