The drills in the Quadro series are provided with two cutting edges and two additional guide chamfers. Thus a total of four guide chamfers allow maximum bore quality to be produced with regard to alignment accuracy, concentricity and position accuracy. Drills from the Quadro-Drill series are also excellent for roundness and diameter tolerance.
