Why the 45-Degree Cutting Angle Makes a Difference
The 45-degree angle of this SEKN insert isn’t just a random detail—it’s key to how the tool handles cutting forces. Picture slicing through wood or metal the way you’d cut a cake: the angled edge lets the insert engage the material smoothly, which leads to cleaner cuts and less resistance. This means less heat generation, less wear on your tool, and a smoother finish on your workpiece.
