⚙️ Benefits and Applicability:

Compatibility:
Compatibility explanations (%):
• 90–80%: Optimal performance, the router bit works efficiently and durably.
• 79–60%: Good processing, but requires maintenance (sharpening or cooling).
• <60%: The wood is too hard or oily, leading to rapid wear of the HSS M2 router bit.
Recommendation: For exotic or very hard woods, router bits made of cemented carbides (Widia) would be a more suitable choice.
