Why the 20° Positive Rake Angle Makes Cutting Easier
The 20-degree positive rake angle on this insert means the cutting edge bites into the material more smoothly, reducing resistance and heat buildup. Think of it like slicing bread with a sharp knife angled just right—it makes the job cleaner and requires less force. This angle helps improve cutting efficiency and tool life, especially when milling tougher metals, so your machine works smarter, not harder.
