一种夹持杆和切削端分离的钻头

Drill bit with clamping rod and cutting end separated from each other

Abstract

The invention discloses a drill bit with a clamping rod and a cutting end separated from each other. The drill bit comprises a cylindrical drill rod with a central axis, one end of the drill rod is the clamping rod, the other end of the drill rod is the cutting end, cutting teeth are uniformly arranged at the cutting end, chip grooves spirally extending from the cutting end to the clamping rod are arranged on the outer circumferential surface of the drill rod, and the drill bit is characterized in that the clamping rod and the cutting end are separated from each other. The drill bit is provided with the clamping rod and the cutting end which are separated from each other, detachable and replaceable, so that only the cutting end needs to be replaced while the clamping rod is reserved after a blade is worn, service life of the clamping rod is prolonged, the clamping rod can be used for a longer time, and resources are saved.
本发明公开了一种夹持杆和切削端分离的钻头,包括具有一个中心轴线的圆柱形钻杆,钻杆的一端为夹持杆,另一端为切削端,切削端均匀设置有切齿,钻杆外圆周表面上设置有从切削端往夹持杆螺旋延伸的排屑槽,其特征在于:所述夹持杆和切削端分离。本发明提供一种夹持杆和切削端分离可拆卸更换的钻头,使得刃部在磨损之后,只更换切削端而保留夹持杆,提高了夹持杆的使用寿命,从而使夹持杆可以使用更长的时间,节约了资源。
