Midwest Phoenix™ series use Diamond-Like Carbon (DLC) coated ceramic bearings to reduce friction for enhanced bearing performance. Dynamic speed control in the head helps maintain cutting power while limiting free speed to help prevent premature bearing wear. Titanium coating on sheath enhances grip while providing a protective coating over stainless steel construction. 4-port water spray. Features and Benefits: • Automatic torque control with ATC control system provides electronic speed control to limit free speed while managing power on demand to protect against excessive speeds that can cause premature bearing failure and excessive noise. • Titanium coating on grip and sheath enhance tactile control while also maximizing scratch and chemical resistance. • Diamond-Like-Carbon coated ceramic bearings reduce friction and enhance performance. • Two-year warranty.
