Abstract
1. Головка (4, 13, 30, 50, 70, 80, 100, 110, 120, 133, 141, 151, 190) бура для соединения со стержнем бура (1, 10), предназначенного для сверления в твердых материалах, прежде всего в природном камне, бетоне или армированном бетоне, и имеющего ось (D) вращения, закрепляемая на обращенном в направлении подачи конце стержня бура, имеющая на своем обращенном в направлении подачи конце острие и ограниченная с противоположной острию стороны соединительной поверхностью (F, F′, 43, 52, 121, 193, 203), которой головка бура может быть соединена со стержнем бура, отличающаяся тем, что отношение (V) диаметра (d) головки бура к ее высоте (h) принимает следующие значения:,причем высота головки бура - это расстояние от обращенного в направлении подачи конца острия бура до соединительной поверхности головки бура, измеряемое в направлении оси вращения, диаметр d головки бура определяется ее максимальной шириной, измеряемой перпендикулярно оси вращения, высота и диаметр головки бура выражены в миллиметрах (мм), диаметр головки бура составляет от 2 до 35 миллиметров, а член с находится в следующем интервале значений: 0,95≤c≤2,85.2. Головка бура по п.1, отличающаяся тем, что она изготовлена из высокопрочного материала, в частности из высокопрочного композиционного материала, включающего в себя по меньшей мере два различных материала, одним из которых предпочтительно является твердый сплав, а другим - керамика или корунд, или выполнена, в частности, в виде цельнотвердосплавной головки.3. Головка бура по п.1, отличающаяся тем, что ее соединительная поверхность (F, F′, 43, 52, 121, 193, 203) выполнена плоской и проходит перпендикулярно оси вращения.4. Головка бура по п.1, отличающаяся тем, что она им�1. The head (4, 13, 30, 50, 70, 80, 100, 110, 120, 133, 141, 151, 190) of the drill for connecting with the drill stem (1, 10), intended for drilling in solid materials, before total in natural stone, concrete or reinforced concrete, and having an axis (D) of rotation, fixed on the end of the drill stem facing in the feed direction, having a tip on its facing end in the feed direction and bounded by a connecting surface from the side opposite the tip (F, F ′ , 43, 52, 121, 193, 203), with which the drill head can be connected to the drill rod, characterized in that the diameter (V) of the diameter (d) of the drill head to its height (h) takes the following values: where the height of the drill head is the distance from the direction of the tip of the drill facing the connecting surface to the connecting surface of the drill head, measured in the direction of the rotation axis, diameter d the drill head is determined by its maximum width, measured perpendicular to the axis of rotation, the height and diameter of the drill head are expressed in millimeters (mm), the diameter of the drill head is from 2 to 35 millimeters, and the term with is in the following range of values: 0.95≤c≤2 , 85.2. The drill head according to claim 1, characterized in that it is made of a high-strength material, in particular a high-strength composite material including at least two different materials, one of which is preferably a hard alloy and the other is ceramic or corundum, or made, in particular, in the form of a solid carbide head. 3. The drill head according to claim 1, characterized in that its connecting surface (F, F ′, 43, 52, 121, 193, 203) is made flat and extends perpendicular to the axis of rotation. The drill head according to claim 1, characterized in that it
