DRYGRES DRY DIAMOND CROWN 68MM M14

DESCRIPTION:
DRYGRES drill bits are ideal for drilling in porcelain stoneware, porcelain stoneware, granite and marble.
Diamond in DRYGRES drills is applied using vacuum soldering technology,
which increases their resistance to high temperatures and friction.

DRYGRES 6-12 mm drill bits are perfect for mounting accessories and decorative elements.
Other DRYGRES 20-75 mm crowns allow for professional preparation of openings for water installations, drains, electrical boxes, etc.

Thanks to the M14 thread, DRYGRES drills can be used directly on the grinder, or thanks to the connector (ref. 05976) on the drill without impact.
The average life of DRYGRES 6-12 mm drills is 25 holes, and for sizes 20-75 mm - 60 holes.
It ALWAYS depends on the type of material and its thickness, and the appropriate cooling and use.

DRYGRES drill bits can drill holes up to 36 mm deep.

DRYGRES 6-12 mm drill bits have wax inside that melts during use for easy cooling
and removal of drilled material particles (drills can continue to be used even after the wax has been exhausted.
The end of the life of the drill is only announced by the complete loss of diamonds).
The side hole in the DRYGRES 20-75 mm bits allows for better cooling and removal of residues after drilling each hole.
Remember to clean and inspect the drill each time before drilling.
The maximum working speed of the drill is from 14000 rpm.

To ensure good hole finish and drill life, the given rotational values should not be exceeded,
At the same time, it is recommended to make circular movements with a drill for better cooling.
