An elongated drill bit has a shank at one end and working end at the
other. A flute portion is between the working end and the shank. The
flute portion is continuous with the shank and working end and is
generally unitarily formed with them. The working end has a pilot tip
with a first cutting portion. A second cutting portion is at the terminus
of the flute portion and is axially spaced from the pilot tip first
cutting portion. The second cutting portion includes a pair of cutting
edges on opposing sides of the pilot tip. Each of the second cutting
edges is on an angle from about 22.degree. to 27.degree. to a line
transverse to the longitudinal axis. The cutting edges are defined by the
junction of a rake face, defined by the flute surface, and a primary
clearance face. Also, a secondary clearance face may be present which is
continuous with the primary face at a different angle. The angle is about
50.degree. to 65.degree. with respect to the longitudinal axis.
