摘要： A drill bit has a shank (4) between a drilling head (3) and an insertable end (5) along an axis (2). The shank (4) is provided with at least two first flutes (34) that run along the axis (2) and at least a second helical flute (31). The first flutes (34) and the second flute (31) cross each other at several crossings (41).The width (35) of the first flute 34 steadily decreases over the area between two adjacent crossings (41) from one of the crossings (41) all the way to the narrowest place (42) and subsequently steadily increases all the way to the other crossing (41).
摘要翻译：钻头在沿着轴线（2）的钻头（3）和可插入端（5）之间具有柄（4）。杆（4）设置有沿着轴线（2）延伸的至少两个第一凹槽（34）和至少第二螺旋槽（31）。第一凹槽34和第二凹槽31在几个交叉点处彼此交叉。第一凹槽34的宽度（35）从两个交叉点之一的两个相邻交叉点（41）之间的区域稳定地减小（41）一直到最狭窄的地方（42），随后一直稳步增加到另一个过境点（41）。
