Review on Niagara Cutter N85658 Uncoated Finishing by Daniel Tonini

This is a quality cutter. I use it on my Shapeoko 2 CNC machine with great results. It's durable too. I screwed up and left my machine unattended while I was milling aluminum and when I came back I found that the groove in the aluminum was clogged and snagged on the drill so it was now cutting very deep grooves in the panel. Instead of vomiting, he just kept chewing. The shank was destroyed (*sad face*) but the end mill seems to have survived the collision and continues to cut normally. I'll microscopy the end mill in the near future to see what the actual damage is; but I'm still very impressed, this bit isn't broken.
