The average life of the DRYGRES 4DRILL Diamond Drill Bits is between 15 and 20 Holes and ALWAYS depends on the diameter of the drill bit itself, the type and thickness of the material, and the proper cooling and use.
The drilling depth of DRYGRES 4DRILL drill bits is 36 mm.
All DRYGRES 4DRILL bits contain wax inside. This wax melts while using the drill bit and facilitates cooling and the evacuation of drilling remains (if the wax runs out, the drill bit can continue working. Only the total loss of the diamond indicates the end of the life of the drill bit.).
