As a cautious milling enthusiast, I deliberated a lot before purchasing this item. But now that I did I can confidently say it exceeded my expectations.As my tests showed, this milling accessory is a beast when it COMES to roughing and finishing. The cutting precision is excellent and the shank diameter is just right for my setup. The only downside i noticed was that it's not the cheapest option out there. Nevertheless, it's worth it if you're looking for high-quality industrial and scientific cutting tools..
