Bit broken on first use. I have been using this type of bit for a long time and there was no such problem. Don't know if the bit is defective or a cheap fake?
For cutting 3/16" edge cast acrylic smooth as glass. I will order more soon. Update: 9-9-2019 the quality of these bits has dropped a lot. I'll look around for another brand. What happened Amana, those beats were amazing but not so much now.
I was an idiot. I did a test cut with this and was so shocked by the quality of the cut that I was completely insane as I forgot to lower the router before moving the fence and the fence broke off. Nothing turned, I was just an asshole and distracted by the quality of the result (perfect satin finish on 1/4" cast acrylic after one pass). Now I'm sad every time I look at this bat in my collection. I can't even bring myself to throw it out I hope to replace it one day.
