    摘要： A cutting tool that includes an elongate body that has a forward end and a rearward end. The elongate body has a fluted portion that beginning near and extends in a rearward direction from the forward end. The fluted portion has a flute that defines a cutting edge. The flute presents a concave cutting face wherein the concave cutting face is defined by a first radius. The flute further presents a concave core surface adjacent to the concave cutting face wherein the concave core surface is defined by a second radius. The flute presents a convex heel surface adjacent to the concave core surface wherein the convex heel surface is defined by a fourth radius.

    摘要： The invention relates to a screw tap (1) having a shaft (100). According to the invention, the function of the screw tap drive in applying cutting force is improved in that a recess is introduced into the front end (4) of the shaft (100), the recess extending with its negative cross-section in the axial direction and suited to receiving a force-fit drive with a positive cross section corresponding to the recess (5).
