When tapping, insert the head cone first to make the center line of the tap consistent with the center line of the drill hole .Rotate both hands evenly and apply a little pressure to make the tap enter the knife, no need to add pressure after the knife is entered . Reverse the tap about 45° every time you turn the tap to cut off the chips, so as not to block . If the tap is difficult to rotate, do not increase the rotating force, otherwise the tap will break
