Carbide Baby gift for drilling rock bits

摘要

1. Carbide clove cone bits for drilling, mounted on the peripheral rows cones having a cylindrical base and a working head ploskosimmetrichnuyu bounded laterally conical surfaces with smooth transitions rounding, characterized in that the operating head has ploskosimmetrichnaya one side tapered portion formed by two diverging from the periphery of the flat or concave surfaces, and on the other hand spheroconical portion formed on top of the sphere and a cone; both sides of the head smoothly interfaced one with drugoy.2. Carbide tooth according to claim 1, characterized in that the fillet radius is between two flat or concave surfaces in any of the cross sections of the working head r, starting from the top of the pick up its cylindrical base surface spheroconical smaller radius r (r r) .3 . Carbide tooth according to claim 1 and 2, characterized in that a peripheral crown of teeth always oriented spheroconical part toward the border crossing primary and reverse cones so that the plane of symmetry of the wedge parts cloves were oriented with respect to the scanning line parallel to the boundary of an inverted cone in range from 0 to 180 ° and at an angle to one another to the extent where n - number of cloves of a peripheral crown.
