How do we drill a tile with a thickness of 5mm glazed, without a glass bit, only the impact bit? What's up? The brick is attached to the wall!
Slowly switch, carefully slow drilling tiles, and then force, this is a meticulous work, luck plus technology, but first of all to check whether the brick affixed to dense, if not dense, ninety-nine percent to break.
Of course, drilling ceramic tile with glass bit is time-consuming and laborious, and the advantage of drilling bit is insurance. In the middle of ceramic tile, special ceramic tile drill is recommended. But when drilling, must use ordinary electric drill, can not use the impact function, after drilling through the cement, then use the impact can.
Glass drill points: 1. tilt first, tiles, glass (other materials) surface grinding a shallow trace. 2., the drill bit slightly after, continue to wear out the deeper crescent mark. 3. put the drill straight and continue at the original speed until the major is finished. (pay attention to water when drilling.)
If the tiles under not hollow cement, Tim is very full, can not grasp, if you should buy a special tile bit, namely triangular bits, it does not produce tremor phenomenon, easy positioning, cut resistance, opening soon, there are the ordinary chuck used on an electric drill to need to pay attention to slow speed in particular, is just beginning to open and slow speed when wearing. When in use, add coolant (not too much, but keep adding water). Drilling can be done on hard materials such as glass, stone and tile. 3MM-16MM have, but don't drill edge or side (away from 2 cm above tile seam), or to use the glass or diamond drill hole, is used to watch the speed slower (800-1000 revolutions per minute or so), continue to water cooling (don't need too much, but continue to add water) non dry drilling! High temperature friction, causing serious wear and tear, affecting the use effect!
