Why the 20° Positive Rake Angle Boosts Your Milling Game
That 20-degree positive rake angle isn’t just a random number — it's like the sweet spot on a baseball bat that gets you optimal force with minimal effort. This angle ensures your cutter bites into the material smoothly, reducing resistance and preventing tool overheating. Think of it like slicing through butter rather than hacking through a block of cheese — less effort, cleaner cuts, and longer tool life. This design helps keep your machine running cooler and your work looking sharp.

- Align the clamp-style insert carefully into the holder slot.
- Ensure the 20° positive rake angle is oriented correctly for your cut.
