I was hoping for better results from this brand, but unfortunately my experience with this router bit was frustrating... As my tests showed, it quickly dulled and did not easily cut through the wood I was working with. I expected a more reliable product considering its high price point in the Industrial and Scientific category..
This is Amana bit, works great, lasts a long time. As expected from Amana. Bought for my X-Carve for 3D relief carving and it does the job perfectly. No complaints.
