Abstract: In a chip-forming machining operation improved results accrue from imparting to the chip - in the course of its formation - a longitudinally extending bulge or thickened portion which significantly stiffens the chip and desirably modifies its form. Locating the bulge adjacent the central part of the chip influences a ring-shaped form of chip, while locating the bulge adjacent an edge of the chip results in a cylindrical form of chip having a fairly constant radius of curvature and a great relatively constant pitch. The cutting tool which provides this stiffened chip has a groove or concavity at the locus where the thickened portion of the chip is desired.

Abstract: A drill bit assembly includes a drill bit having a leading end to which a drill tip is bonded. The drill tip has a front cutting edge, a pair of side cutting edges, a rear end and a pair of parallel side walls extending between the respective edges. The leading end is arranged to support the drill tip along the rear end and against the parallel side walls. The drill bit includes a bore extending axially therethrough and opening into the leading end. The drill tip extends across the bore but permits egress of flushing liquid from the bore. The drill tip includes projections arranged to cooperate with an engagement face formed at the leading end to locate the drill tip in a bonding position relative to the leading end prior to bonding of the drill tip to the leading end. The cooperation is such as to resist shifting movement of the drill tip in a direction of elongation of the tip and out of the bonding position.

Abstract: A device for chip forming machining including first and second rotatable bodies arranged along a common axis of rotation. The first body forms a male element, and the second body forms a female element into which the male element is threaded for forming a threaded joint. The male element has an outer circumferential area displaced in the axial direction in relation to the thread thereof and which engages a corresponding inner circumferential area of the female element by a press-fit. One or both of those circumferential areas has an out-of-roundness, such that there occurs a press-fit along two or more preselected regions in the circumferential direction.
