Abstract
1. Режущий элемент, содержащий хвостовик, коническую режущую часть, имеющую узкий конец с гнездом для размещения вставки и широкий конец, соединенный с хвостовиком, и вставку, закрепленную в указанном гнезде, причем вставка имеет наружный слой из карбида вольфрама и внутренний сердечник из материала, твердость которого больше твердости наружного слоя. ! 2. Режущий элемент по п.1, в котором внутренний сердечник выполнен из алмаза. ! 3. Режущий элемент по п.1, в котором вставка образует острие на конце конической режущей части, а внутренний сердечник открыт на этом острие. ! 4. Режущий элемент по п.1, в котором широкий конец конической режущей части шире хвостовика, в результате чего между конической режущей частью и хвостовиком образован уступ. ! 5. Режущий элемент по п.1, в котором указанная коническая часть имеет цилиндрическую ось, а вставка находится на этой оси.1. A cutting element comprising a shank, a conical cutting part having a narrow end with a socket for accommodating an insert and a wide end connected to the shank, and an insert fixed in said socket, the insert having an outer layer of tungsten carbide and an inner core of material, whose hardness is greater than the hardness of the outer layer. ! 2. The cutting element according to claim 1, in which the inner core is made of diamond. ! 3. The cutting element according to claim 1, in which the insert forms a tip at the end of the conical cutting part, and the inner core is open on this tip. ! 4. The cutting element according to claim 1, in which the wide end of the conical cutting part is wider than the shank, resulting in a ledge between the conical cutting part and the shank. ! 5. The cutting element according to claim 1, in which the specified conical part has a cylindrical axis, and the insert is on this axis.
