Description
Why the 6.35 mm Thickness Matters
Thickness is the most overlooked spec on a turning insert. A thicker insert resists the bending load that a deep cut applies, and it conducts heat away from the cutting zone more effectively. The DNMG 150608 is a third thicker than a standard CNMG 120408, and on heavy cuts you feel that difference in edge stability rather than in the catalogue.
That is why the DNMG is often the right answer on larger diameter shaft work and on machines that will happily pull a deep cut – it takes the load without the corner deflecting.
When to Choose DNMG
- Combined roughing and profiling on the same component, where you do not want to index between two tools.
- Larger diameter shaft turning where the cut is deep and the insert needs the thickness.
- Shallow contours that a CNMG cannot follow but which do not need the extreme reach of a VNMG.
- Heavier cuts on capable machines where the extra thickness translates directly into edge stability.
