Solid carbide tungsten fishtail drill is suitable for pcb flexible foil clad laminate,used for target machine drilling,the features of pcb fishtail drill are thin and flexible plate,it's structure and cutting methods are different with normal pcb drill bits.its two main cutting edge is concave and formed 100degree angle,in order to distinguish with PCB drill,named fishtail drill.fishtail drill cuts beginning of circular drill.concave along the main cutting edge to cut,chip is just two much fine filament.cuttingis falling off naturally,in order to be processed without burrformation by pcb surface.

整体硬质合金鱼尾钻适合印制电路板行业加工挠性覆箔板，为打靶机钻孔用。鱼尾钻所加工的印制电路板特性是薄板、带柔性、这样就决定了它的结构和切削方式与一般PCB钻不一样，它的两主切削刃是内凹的，两主切削刃形成100度的夹角，为了与PCB钻区别，就叫它鱼尾名。鱼尾钻切削时从我圆处钻尖开始，沿着内凹的主切削刃切削，切屑只是两条极细丝状切削，整个切削自然剥落，从而被加工印制板表面平整无毛刺。
