  PEAK PERFORMANCE (with water)

Constant cooling water. More than 15 holes in hard porcelain PEI 5.

  GOOD PERFORMANCE (low water)

Interruption of drilling every 6 seconds. Strong pressure on the bit for a short period of time at high speed and stop the drilling, dipping the tip of the bit in a small container of water (a cup with some water). It is an ideal method for placement of screens and vertical works. Can overcome 10 holes in hard porcelain PEI 5.

  AVERAGE YIELD (without water)

Interruption of drilling every 5 seconds. Strong pressure on the bit for a short period of time at high speed, stop drilling, 3-4 seconds running “the air”(for short cooling). Approximate 6 to 8 holes in hard porcelain PEI 5.

  LOW PERFORMANCE (without water)

At high speed, with strong pressure, without interruption of the drilling water or for cooling the bit, will I get the lowest performance. Using this method does not usually exceed 5 holes in hard porcelain PEI 5.

  RECOMMENDATION

For more than 7.0 mm holes, with not guaranteed material,  we recommend to use previous drill bit (5mm) to avoid any trouble (breaking tiles).
