🐍 Cobra Carbide 27304 Hi Performance Diameter: Unleash the Power! Review

It's not 60 degrees horizontal, it's 60 degrees vertical, so instead of the router shown in the photo, you're getting this thing that looks more like a lead screw on a 3D printer than a consumer CNC end mill. And while this is probably normal for most CNCs, it's a big problem for Shapeoko. On the first cut, when the drill moved about 60% of what I normally use with the trusted 4-blade 30-degree
