Dormer Pramet Releases LNEX 12 Insert, SLN12X Cutter

Dormer Pramet, Czech Republic, a global manufacturer and supplier of tools for the metal cutting industry, released the LNEX 12 insert designed for shoulder milling and the SLN12X cutter.

The LNEX 12 is a robust insert designed for shoulder milling with a maximum depth of cut up to 10 mm. It features a positive rake angle and narrow T-land to provide a smooth cutting action with lower demands on spindle torque.

The peripherally ground insert offers improved wall accuracy and straightness creating a true 90° corner. The LNEX12 also features a patented U-groove segment on all four cutting edges providing a good surface finish and expands its application range to low-power machines and small depths of cut. In addition, the two-sided design supports performance by making ramping possible.

The insert comes in two different geometries: F for machining various workpiece materials in light and medium applications and M is suited for medium to semi-roughing in steels and cast irons.

Alongside the new insert is a line of perfectly matched cutters. The Pramet SLN12X series is available in cylindrical, weldon and shell styles, featuring internal coolant systems for improved surface quality.

Its improved body strength and thick core offer enhanced rigidity, giving a reliable cutting process with low vibrations and long tool life for both the insert and cutter. Easily accessible large clamping screws provide simple indexing and handling of inserts.

The combination of the LNEX 12 inserts and the SLN12X cutters gives operators a smooth cut with a clean finish, reducing the need for additional operations, such as deburring.
