Operation Tips for Vacuum Brazed Diamond Drill core bits
 1.Do not use these drill bits with hammer mode
 2.Only fit these drill bits on a cord drill, not cordless drill(no enough power)
 3.Only for tile drilling not recommend for the material behind the tile
 4.For horizontal drilling,just give a gentle pressure
 For vertical drilling, the weight of the machine will give sufficient pressure
 5.Start drilling as per following instructions:
 1) Place the drill at a 45 degree angle
 2) Drilling till the hole start to form
 3) Bring the drill up into upright position
 4) Continue to drill and swaying the machine along a circle
