Abstract: The invention relates to a rotary cutting tool (3) that is composed of a tool shank (2) with at least one chucking groove (5) and one exchangeable cutting insert (1). At the tip (4) of the shank as well as in the wall of the chucking groove (5) a recess (6) for accommodating the cutting insert (1) is provided and is delimited on the shank-end by a rim (7) against which the shank-end narrow side (12) of the cutting insert (1) rests. The cutting insert (1) comprises a fastening pin (15) which is accommodated in a location opening (16) of the tool shank (2) that is concentric to the tool axis (A). The tool shank (2), on its circumference, has a limb (9) with a bearing surface (8) that is inclined relative to the tool axis (A) and that corresponds to a likewise inclined bearing surface (10) on a wing (11) of the cutting insert (1). The orientation of inclination of the bearing surfaces (8, 10) corresponds to the direction of rotation (D) of the tool. The inclination of the bearing surfaces (8, 10) produces an axial force that retains the cutting insert (1) on the tool shank (2).

Abstract: The invention relates to a drill bit (2), having main cutting edges (4a, 4b) which are connected together by a transversal cutting edge (6). An open surface (7) which extends into a flute (8) lies adjacent to each main cutting edge. The drill bit (2) is ground, in particular, during a continuous three-dimensional grinding process in such a way that the open surface (7) forms a continuous curved surface which follows a radius of curvature (R) running from the main cutting edge (4a) in the direction of the flute (8). The continuous grinding process, in comparison to a conventional two-stage process, produces an improved drill bit geometry which is devoid of ridges (16). The ridge-free configuration reduces the mechanical stress during drilling to a minimum.

Abstract: The invention concerns a drill with a least one central channel for cooling-lubricant oil feed. The drill has a shaft with at least one flute (4) running in a spiral round the shaft axis. Whereas in conventional drills of this kind the oil channels end in outlet apertures in the flanks of the main cutting edges, this is not the case with the drill proposed. Instead, the oil is fed to the point of application of the drill through lateral outlet apertures which are joined to the at least one oil channel (18) by connecting channels.

Abstract: Disclosed is a drill comprising at least two cutting edges (7, 8) and one respective at least partly spiraled cutting groove (9, 10) that extends from said cutting edges (7, 8) towards one end (6) of the shaft. The inventive drill further comprises a cooling channel (13, 14) which extends from said end (6) of the shaft and runs parallel to the tool axis (A). The outlet port (15, 16) of said cooling channel (13, 14) is located inside the cutting groove (9, 10) while being oriented towards the cutting edge (7, 8).

Abstract: The bit (3) for a twist drill (2) has several main cutting edges (4) which are interconnected by a chisel edge (6). Secondary cutting edges (14) running along flutes (10) in the longitudinal direction (L) of the drill adjoin said main cutting edges. The secondary effective cutting angle η associated with the secondary cutting edges (14) changes in the longitudinal direction of the drill (L). The main cutting edges (4) are preferably configured in a straight line so that the secondary effective cutting angle in this area is 0°. The adjoining secondary effective cutting angle η increases continuously. This enables the bit (3) to absorb greater loads in the area of the main cutting edges (4) and at the same time, guarantees that the chips are removed rapidly from the bore wall of the workpiece to be processed.
