摘要： A drill with a drill flute (12) includes symmetrical fluted lands (20) helically extend around a core, wherein grooves (18) remain between the fluted lands, said grooves having a width (72) that exceeds the spine thickness or width (24) of the fluted lands (20), and wherein the grooves (18) comprise a convex core reinforcement (22) at the groove bottom thereof. The width (24) of the fluted lands (20) at the drill head side end (16) is smaller than at the shank side end (14) of the drill helix (12), and at least increases in certain areas. The core reinforcement (22) at the drill head side end (16) is more convex than at the shank side end (14), thus has larger radii (40, 42).

摘要： The radial run-out tool (2), particularly a drill or a cutter, has a basic body (12) extending in an axial direction (4) and comprises at least two chip grooves (14), to which a guide chamfer (22) is connected in the rotational direction (24), with a ridge (15) being formed between them. A radial clearance is connected to the guide chamfer (22). In order to enable simple and economical production of such type of radial run-out tool (2), an unprocessed rod (30) is ground non-concentrically, in a first process step, such that a radius (R) of the unprocessed rod (30) varies, depending on the angle, between a maximum radius (R2) and a minimum radius (R1). In a second process step, the chip grooves (14) are grounded down such that the guide chamfers (22) are formed at the positions with the maximum radius (R2) and the radius (R) is subsequently reduced downstream of the respective guide chamfer (22) in order to form the radial clearance (28).

摘要： The invention provides a cutting head for a drill bit, the cutting head comprising four substantially identically shaped cutting arms extending radially from a common central axial point, each cutting arm comprising a cutting edge extending outwardly and axially backwards from the common central axial point. The cutting edges are equiangularly spaced apart from each other about the central axis of the cutting head. Each cutting arm further comprises a side chamfer extending between its radially outer face and its rotationally trailing side face.

摘要： A drill bit having features rendering it particularly effective in cutting holes in carboresin laminates of the type used in the aircraft industry. A pair of diametrically opposite lands slope radially inward at the working end of the bit to a pair of cutting edges disposed at an obtuse angle to one another and forming an efficient cutting tip. Notches with sloping ramps adjacent the cutting edges efficiently convey cut material to adjacent flutes. The lands curve radially inward between their full diameter portion and their cutting tips and the junction of the curved portion and the constant diameter portion of the lands is machined to provide a more gradual transition.
