Help with double layer vcarve

[WillAdams (William Adams (Carbide 3D))]

The problematic tool (for me) is the RC-1142 which other folks have noted vibrates quite a bit:

90 degree Amana bit vibrating like crazy

Wondering if this is normal. Finally got to use my new Amana bit last night. Usually the machine is pretty quiet but when I put this bit on it immediatly had a ton of vibration and was way louder than normal. Is a bit this size normal to make the router make this noise or not? Not sure if it matters but here’s a video.
