Q: What shank size does this spiral router bit use?

Q: What materials can this spiral router bit cut?
A: The YG8 alloy spiral router bit is suitable for trimming and flush cutting solid wood, MDF (medium-density fibreboard), plywood, and laminated boards. Its spiral edge design ensures clean, smooth cuts on all these materials.
Q: What is the recommended operating speed for this router bit?
A: For optimal performance and a clean cut finish, this bit is recommended to be used at 18,000 to 24,000 RPM. Always ensure your router is set within this range for safe and efficient operation.
Q: Why does this bit have both upper and lower bearings?
