Warm tips :
①The best use of this product is to use a bench drill, because the hand electric drill is not fixed in the operation process, the drill bit (especially the 3mm and 4mm) is prone to bend and break!!!
â‘¡Try to keep the drill vertical while drilling, so as not to be uneven.
â‘¢It is recommended that the drill be clamped within a range of 10 mm and bits should be used within the clamp range
