How the 20-Degree Positive Milling Design Improves Your Machining
The 20-degree positive angle on the SEAN-42 AFN insert helps reduce the resistance during cutting, kinda like slicing a ripe tomato instead of a hard one. This angle softens the impact on your materials and tools, allowing smoother chip flow and less heat buildup. What does that mean for you? Less wear and tear on your machine and a cleaner finish on your workpiece. It’s a simple twist in design that keeps your milling process running cooler and longer, making your job way easier.
