Here are some warm tips】 ● Keep the bit vertical and fixation while drilling. ● To avoid drill bit break, 1/16” or smaller bits are suggested used with pin vise.  ● Pay attention to the cooling of the bit, adding water or coolant when drilling can increase the life of the bit. 【Warranty: 90 Days】 No worries!
