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: • Larger diameter rotor design provides more power than smaller versions. • Dynamic speed control in the head helps maintain cutting power while also protecting 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.
