    摘要： A reverse spot-facing tool for cutting a reverse spot-face in a workpiece using a reverse spot-facing cutter configured to engage a pilot shaft having a first end and a second end is disclosed. The workpiece comprises a through hole having a central axis. The reverse spot-facing tool comprises a stop configured to be located between the first end and the second end of the pilot shaft; a biasing assembly that generates a first thrust force and an equal and opposite second thrust force when the reverse spot-facing cutter is cutting the reverse spot face; and a thrust bearing configured to be positioned between the biasing assembly and the stop. When the reverse spot-facing cutter is cutting the reverse spot-face, the thrust bearing transmits the second thrust force from the biasing assembly to the stop, and the biasing assembly transmits the first thrust force to the workpiece.

    摘要： A drill countersinking and seal groove machining tool to accommodate an accurate drill countersinking and seal groove machining operation. The linear compensator tool applies sufficient force to react to the drilling or seal groove machining process, but not so much force as to distort the work piece being drilled or machined. The tool ensures that the reactant force does not exceed the machine force override allowances. Varying spring rates and/or air pressures on the linear compensator system will accommodate most applications. The tool absorbs over travel of the machining tool, in order to ensure that the surface to be machined is always in contact with the machining tool.

    摘要： A drilling bit with the depth-limiting and angle-leading function for the carpenter's work, having a covering sleeve (with a driving shaft) and a bit holder for securing a bit. A limit ring and a screw socket (with female thread) are screwable to the covering sleeve (with the male thread) for adjusting the depth of the spot-faced hole in a workpiece (to be drilled) according to the actual operation requirement.

    摘要： In a device for limiting the advance during a drilling operation, which can be used in conjunction with a hand drill or with an automatic manufacturing machine, the device comprising a housing with a stop cage and a spindle mounted rotatably and axially displaceably in the housing, and a stop which is adjustable in the axial direction being arranged for limiting the advance, the invention consists in that the stop cage (2a) comprises a pin fixed to the housing 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 in such a way that its free end almost touches the countersink. 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.
