The bright finish on these drill bits is not affected when the bits' cutting edges are resharpened. Parabolic-flute drill bits have wide, deep flutes that improve chip flow and heat dissipation, which means feed rates do not need to be reduced as the drills move deeper into the workpiece. These bits have a straight shank that installs into a drill chuck or similar toolholder.
