A drill configured for drilling ductile materials includes a drill margin with a margin extremity adjacent to a relief surface. The drill includes a drill body and a drill head secured to the drill body via rotational coupling of the drill head on the drill body.

Drill or drill head with burnishing margin

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.

Cutting tool

As seen in a side view of a cutting insert, the cutting insert is provided with cutting edges that slope in opposite directions. A rake surface extends at the upper surface inwardly from the cutting edges. An inward portion of the rake surface forms a main chip former. A first end of the rake surface adjacent a raised cutting corner and distal a lower cutting corner is provided with a secondary chip former that extends from adjacent the raised cutting corner to the main chip former.
