The drill There is a secret process as follows:1. turn grinder hand table without standing in front of a stone wheel directly. To stand beside the stone wheel, because centrifugal opening for the first time have more strength. Grinding stone, and rotate the slide before he cut back the sharp cut.2. use the left hand grip at the end of the drill. The right hand part to handle gently at the end of the drill, where the left hand is placed on the podium when cutting stone support work with long sharp movements of the cutting wheel, grinding stone to drill slowly.3. when viewed from the top of the drill angle to the skin in front of the grinding stone 59 degrees (sharp sharp 2 both sides, secret and equal.)4. entrance drill movements touch on the wheel grinding stone. Notice the sharp cut of the drill were good secrets until the sharp end of the sharp kradok, cut up, with a twist, Rotate clockwise to drill to cut an angle of 12 degrees 8-free.5. tilt angle drill grinding with face wheel stone 59 degrees clubs (Cutting Angle) is an angle as well as the end of the drill, which will have a different angle sizes depending on the type of material to be drilled, such as iron, clay, the General view as well as 118 degrees (59 degrees is equal to one half)6. gently twist drill to spin with more pressure. To make a sharp corner cutting free of the back doing this, both sides of the sharp cut drill.7. the angle of the drill, which if correct corner is available in the length of the cutting edge, both sides must be equal.8. While the secret to cooling water dipping drill frequently to secret cooling drill alternating each side until equal angle size as needed.
