ABSTRACT A single-lip solid drilling tool has a one- piece shank with an integral head having a radially or diametrically extending groove for a blade with an eccentric tip. The blade is held in its groove by several clamping screws so that it can be removed for sharpening or for replacement with a fresh blade. One or both lateral portions of the blade extend beyond the periphery of the head to guide the tool in actual use. The shank has an eccentric coolant hole whose discharge end is adjacent the blade and which is formed by providing a short cylindrical hard-metal blank with an eccentric axially parallel bore before the blank is stretched to reduce its diameter to a requisite value and to simultaneously reduce the diameter of the bore. The stretched blank is then machined to provide it with one or more chip evacuating flutes and, if necessary, with one or more grooves for discrete guide members which extend beyond the peripheral surface of the head. - 1 -
