| 摘要 |
The invention relates to a cutting element for a drill, designed for rotating about a rotary axis (R) when drilling and comprising at least one first grinding particle type (1). In order to increase the effectiveness and service life of the cutting element, in particular when drilling reinforced concrete and similar materials, as well as user comfort, in particular by reducing vibration and noise, the content of grinding particles of the first type (1) increases continuously and/or incrementally from the rotary axis (R) of the cutting element to the periphery (P) of the cutting element. |
