Special geometry with extremely unequal spacing and matching cutting edge preparation. Radially relief ground. Flutes ground from solid. Newly developed special TiAlN coating for long service life. 15 0388 High-precision countersink, produced with tight manufacturing tolerances similar to DIN 335-C. Advantage: Very smooth cutting throughout the entire countersinking operation. Chatter-free running for perfect results and optimum tool service life. Extremely unequal spacing Application: High-precision countersinks for production of exactly round 90° countersunk surfaces. (cutting edges arranged at unequal Very well suited to virtually all materials. Advantage in comparison to HSS countersinks intervals). especially in the field of high-tensile steels and because the working life is several times longer.
