Abstract
A cutting tool of the sort used for deep hole drilling has a cutting head mounted on a shank. The cutting head is formed asymmetrically with respect to a longitudinal axis and has at least one cutting edge. The cutting head has guiding segments that extend from a forward end to a rear end of the cutting head. Each of the guiding segments has a guiding pad in the periphery thereof. A forward end of the guiding pad lies on a cylindrical envelope defined by the cutting diameter of the cutting tool. A rear engagement portion of the cutting head is engaged with a forward engagement portion of the shank. The cutting head is made from sintered carbide powders and the guiding pads are integrally formed with the cutting head.
