Резец используется преимущественно для бурения шпуров (скважин) по углям и горным породам крепостью f до 8 по шкале проф. М.М.Протодьяконова. Сущность изобретения: резец для вращательного бурения, включающий два пера и твердосплавные пластины с главной режущей кромкой в виде асимметричной ломаной линии и выполненным на передней грани пазом с наклонными стенками, образующими между собой тупой угол. Новым в резце является то, что элемент ребра выполнен от вершины каждого пера до линии пересечения плоскости контакта резца со штангой с плоскостью, параллельной задней грани твердосплавной пластины и касательной корпуса резца. Положительный эффект: повышение технологичности изготовления и восстановления резца в процессе эксплуатации, производительности бурения и надежности резца в работе.The cutter is used primarily for drilling holes (wells) in coal and rocks with a fortress of f to 8 on a scale of prof. MM Protodyakonov. The inventive cutter for rotary drilling, comprising two feathers and carbide plates with a main cutting edge in the form of an asymmetric broken line and a groove made on the front face with inclined walls forming an obtuse angle between them. New in the cutter is that the rib element is made from the top of each pen to the line of intersection of the plane of contact of the cutter with a rod with a plane parallel to the rear face of the carbide plate and the tangent body of the cutter. Positive effect: increased manufacturability and restoration of the tool during operation, drilling performance and reliability of the tool in operation.
