Frequently Asked Questions
Q: Can this end mill be used to plunge cut? A: Yes, it is a center-cutting end mill, meaning it can plunge directly downwards into the material.
Q: What is the benefit of the 8% Cobalt? A: The addition of cobalt increases the tool’s hot hardness, allowing it to cut tougher alloys and run at higher speeds without failing.
