Why the 80-Degree CNMA Style Makes a Difference
The 80-degree angle of the CNMA insert isn’t just a number—it plays a big role in how smoothly and accurately your cutting goes. Think of it like the angle of a ski on a slope; too steep or too shallow, and you won’t have the best control. With this angle, you get an ideal balance that allows the insert to slice through metal efficiently while maintaining strong edge strength. This means you get cleaner cuts and a longer-lasting tool, which saves you time and money in the long run.
