Face Milling Insert SEMT13T3 or SEKT13T3? How to choose?
At present, Mitsubishi SEMT13T3AGSN-JM VP15TF is widely used and loved by many metalworking factories. Mitsubishi describes this model like this: High accuracy M class insert. For a wide range of work piece materials and cutting conditions.
Our make SEKT13T3AFTR in tungsten carbide material and cermet material.
So what is the difference between the “M” and “K” class?
According to the ISO CNC insert code naming rules, the 3rd symbol refer to the tolerance or the precision of the insert.
| Symbol | Tip height (mm) | ΦI.C (mm) | Thickness (mm) |
| M | ±0.08-±0.18 | ±0.05-±0.13 | ±0.13 |
| K | ±0.013 | ±0.05-±0.13 | ±0.025 |
In general, “K” class has higher accuracy than “M” class. In terms of accuracy, SEKT13T3 has higher accuracy than SEMT13T3.
Then many people will ask: Does your SEKT13T3 can match our Mitsubishi face mills? Should we import your SEKT13T3 face mills from your company? Then our current face mills cannot be used, and the shipping cost will be higher.
Yes, this is a problem that many customers will be concerned about. But we can tell you very clearly that you don’t have to worry about these issues at all.
Below is our explanation of this problem:

| Model | LE | IC | S | BS | KRINS | AN |
| SEKT13T3AFTR | 13.38 | 13.38 | 3.97 | 2.77 | 45° | 30° |
Our has the courage to innovate. Our customers has positive feedback about our carbide material SEKT13T3 with coating. However, some customers has higher requirement for the insert. A part of clients use SEKT13T3 face milling inserts to process steel parts, and they want a higher surface finish. Therefore, we produce new material: cermet material without coating. The cermet insert without coating is very suitable for semi-finishing and finishing of the steel parts processing, and can achieve a higher surface finish.
Our is located in Zhuzhou City, and tungsten carbide inserts blank here is in the top quality of China. If you are interested in our square face milling inserts, please feel free to contact us.
