When the battery is full of electricity, the self-tapping screw can be used for about 2-3 hours. The specific use time depends on the hardness of the actual material and the size of the screw, for reference only. machine unscrew screws and boreholes provide torque optimization. Large torque, low speed, suitable for screw. Low torque, high speed, suitable for drilling. The 1-20 on the fuselage is 20 block torsion adjustment, indicating the size of the machine screw force, the greater the number, the greater the force, the smaller the 20 force. The machine with torsion adjustment can achieve better screw effect.

電池滿電狀態(tài)下，擰自攻螺絲大約可以使用2-3小時，具體的使用時間取決于實際被擰材質的硬度以及螺絲的大小，僅供參考哦。 機器起擰螺絲和鉆孔提供的扭矩優(yōu)化。1檔扭力大，轉速低，適合擰螺絲。2檔扭力小，轉速高，適合鉆孔。機身上的1-20是20擋扭力調節(jié)，表示機器擰螺絲力暈的大小，數(shù)字越大力暈越大，1力量小20力量大。帶扭力調節(jié)的機器可以實現(xiàn)更好的擰螺絲效果。
