Review on Tungsten-Cutting Hardwood Milling Tool by HQMaster by David Dober

I've had great results with this cutting 6061 aluminum. They won't hold a sharp edge for long, but the simple geometry of the single groove means I can most likely rework it on my grinder. I'll just try to match the contours to my new ones. Keep in mind that they are all slightly smaller but consistent (5.75mm) which isn't a problem when you factor that into CAM.
