      Description

      Version:

      All countersinks have 3 cutting edges. 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.
      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.

      Application:

      High-precision countersinks for production of exactly round 90° countersunk surfaces.
      Very well suited to virtually all materials. Advantage in comparison to HSS countersinks especially in the field of high-tensile steels and because the working life is several times longer. Shank tolerance h6 - suitable for mounting in hydraulic chucks or shrink-fit chucks.
