    Abstract: The drill of the present invention has only one cutting discharge groove (11) formed in the outer periphery of a bit (10). A leading edge protruding farthest towards the tip in the axial direction in a tip flank (12) is composed at a single point and located on an axis (O). When bit is viewed from the tip side in the direction of axis, tip flank is in the form of a multilevel surface composed of second through fourth flanks (14B, 14C and 14D) arranged along the peripheral direction, and a reverse side first flank (14E) surrounded by second through fourth flanks and intersecting with axis.

    Abstract: A centering feature (230) on a drill bit (110) configured without a pointed tip, formed as an opening (230) between first (206) and second (208) relatively angularly inclined portions of a work engaging end (116) of the drill bit (110). The first portion (206) of the work engaging end (116) is defined by a cutting edge (134), and the second portion (208) is defined by an end face side boundary (216) transversely aligned with the cutting edge (134). The cutting edge (134) and end face side boundary (216) are offset from each other to create the opening (230), which permits the drill operator to view a punch mark or other indication on the work piece where the center (232) of the intended hole is to be located. The drill operator positions the medial termination point (212) of the cutting edge (134) of the drill bit (110) over the center hole location (232) preparatory to contacting the drill bit (110) against the work piece to cut the hole.

    Abstract: A first embodiment of a non-adjustable single cylindrical lip boring tool includes a shank, a body, a straight side lip, and a front cutting edge. The shank is formed on an end opposite the body. The straight side cutting lip is formed on the body. The straight side lip has a radially convoluted relief which blends into the body. A second embodiment of a non-adjustable single cylindrical lip boring tool includes a shank, a body, a helical side lip, and a front cutting edge. The shank is formed on an end opposite the body. The helical side lip is formed around the body. The helical side lip has a radially convoluted relief which blends into the body. Both embodiments of the non-adjustable single cylindrical lip boring tool may be sharpened on a hand grinder.

    Abstract: A short-hole drill bit and short-hole drilling method in which a drill bit has a unitary body with a substantially V-shaped flute and a support pad are provided. The unitary body has a shank portion and a working portion. The flute extends axially along the working portion, and defines a cutting edge and a passive edge at the body periphery. The support pad is located along a portion of the body periphery. The support pad is located with respect to the cutting edge based on a normal cutting force and a tangential cutting force at the cutting edge. The resultant cutting force is directed at the support pad to cause the support pad to center the short-hole drill bit during operation.

    Abstract: A high speed drill bit is formed of a longitudinal body designed to rotate about a longitudinal axis. Each flute has a leading edge with a positive rake angle and a trailing edge with a neutral or negative rake angle. The bit cutting face is formed by surfaces and cutting edges that are asymmetrical with respect to each other.
