Abstract: A tool shank for use with a cutting insert in a rotary cutting tool includes a body having, and adapted to be rotated about, a central longitudinal tool axis, the body having a tip portion structured to receive at least a portion of the cutting insert therein. The shank also includes a pair of chip flutes formed in the body and a pair of recesses, each recess bordering a respective chip flute. Each recess includes a rim portion extending perpendicular to the tool axis and a bearing surface extending at an incline relative to the tool axis. Each rim portion is adapted to engage a corresponding surface on the cutting insert. Each bearing surface is adapted to engage a corresponding bearing surface on the cutting insert in a manner such that the cutting insert is pulled against the body when the rotary cutting tool is rotated about the tool axis.

Abstract: A rotary cutting tool that is composed of a tool shank with at least one chucking groove or chip flute and one exchangeable cutting insert. At the tip of the shank a recess for accommodating the cutting insert is provided. The tool shank, on its circumference, has a limb with a bearing surface that is inclined relative to the tool axis and that corresponds to a likewise inclined bearing surface on a wing of the cutting insert. The inclination of the bearing surfaces produces an axial force that retains the cutting insert on the tool shank.

Abstract: The present invention is directed to a helical drill configuration that allows substantially flat bottomed holes to be machined. At the cutting end of the body member, there are at least two cutting edges that are symmetrically oriented on opposing sides of the rotational axis of the drill. In an embodiment of the invention, first and second cutting edge portions form a continuous surface which provides strength and tool stability. The height of the second portions of each of the cutting edges remains relatively consistent along the horizontal for formation of a generally flat bottom hole. In the embodiment, a center point is defined by two sloped peak surfaces. A central straight chisel edge is formed by the intersection of the two sloped peak surfaces. The first cutting edge section extends from the chisel edge to the second cutting edge section. The first cutting edge section for both cutting edges is formed by symmetrically thinning the two peak surface.

Abstract: A twist drill including a cutting tip having a front flank face, a substantially cylindrical tool body extending rearwardly from the cutting tip, and a shank. The tool body includes a rotational axis therethrough and at least one flute formed on an outer peripheral surface thereof and extending to the front flank face. The at least one flute includes a first helical portion opening to the front flank face and a second helical portion extending from the rear end of the first helical portion toward the rear portion of the tool body. The second helical portion twists in a direction opposite of the first helical portion.

Abstract: A windshield wiper system in which a dedicated microcontroller controls not only the wiper motor, but also a solenoid which provides dynamically variable downforce on the wiper blade.

Abstract: A brushless DC motor in which increased rotor resistance is used to facilitate very frequent reversals. The rotor endcap is thinned down to the point where the resistance seen by the path of the current loop through one of said endcaps, is at least one-half as much as the resistance seen by the portion of said current loop which flows along the length of one of said rotor bars.
