    • The invention pertains to a recessing tool insert for use in machining work pieces. It comprises at least one leading cutting edge (14) which is interrupted by two axially symmetrical groove-type recesses (17, 18) which are set into the cutting face (13), parallel to the blade's longitudinal axis and of uniform width (B) over their entire lengths (L). The distance (A) between the groove-type recesses is 30-80 %, preferably 40-65 %, of the cutting width, i.e. cutting edge length. The depth (T) of the groove-type recesses in relation to the surrounding cutting face (13) is between 0.01 and 0.4 mm.

    • Disclosed is a cutter insert for machining workpieces, the insert having a front cutting edge (15) disposed at right angles to the longitudinal axis (25) of the insert, a central concave chip-forming depression (23) delimited at each side by chamfers (21, 22) to protect the cutting face. Behind each of the chamfers (21, 22), facing towards the chip-forming depression (23) and extending out into the depression, are nose-like chip-forming elements (24) which are disposed symmetrically with respect to the longitudinal axis (25) of the insert and which abruptly narrow the bottom face of the chip-forming depression, preferably non-continuously, in the chip-runoff direction.

    • In a device for limiting the advance of a drill during a drilling operation, which can be used in conjunction with a hand drill (15) or with an automatic manufacturing machine, the device comprising a housing (2) with a stop cage (2a) and a spindle (3) mounted rotatably and axially displaceably in the housing, and a stop (9) which is adjustable in the axial direction being arranged for limiting the advance, the invention consists in that the stop cage (2a) comprises a chip breakes (13) for breaking the chips, with a housing-side end and a free end, in such a way that it extends approximately parallel and directly adjacent to the workpiece surface and approximately radially from the outside towards the drilling tool (stepped drill bit 12) in such a way that its free end almost touches the countersink (12b) . Damage to the surface of workpieces is prevented by the invention, so that corresponding refinishing is avoided. Moreover, the removal of the coiled chips from the drilling tool previously necessary after each drilling cycle is dispensed with.
