    摘要: A wood boring bit for boring holes in wood and other similar work surfaces having a central longitudinal axis, a main body, a pilot screw tip and a partial flute with a cutting edge and a cutting spur. The flute portion may be defined by a partial helical section having a distal end joined to the main body and a lead edge disposed toward said screw tip. The distal end and the lead edge preferably do not overlap along the central axis and are equal to or less than 360° from one another around the axis. The partial flute provides improved waste removal and allows the user to access the cutting edge of the flute for maintenance purposes.
