Roughing and finishing tools with unique chipbreaker geometry deliver higher productivity with less horsepower than other high-performance mills. Our exclusive flute design reduces cutting forces, creating smaller chips that can be removed faster and easier thus eliminating the cause of most tool chatter. Titanium Aluminum Nitride coating (TiAlN). Excellent for high strength steels, hard die steels and high temperature alloys and titanium alloys. Possible for dry machining, which eliminates thermal shocks created by flood coolants cutting temperatures.
