Rubi Drygres 4Drill Dry Diamond Drill Bit, 5924, 8MM Bit Dia

The Rubi Drygres 4Drill Diamond Drill Bit have been designed to be used exclusively with a corded or cordless electric drill, always without a hammer. Their hexagonal connection allows them to be quickly adapted to drills. Being dry cut, it is necessary, for a correct cooling of the drill, to carry out a slight and constant orbital movement during drilling, as well as to remove any remaining material, between drilling and drilling. Rubi Drygres 4Drill drill bits have a system that blocks the loss of this wax from the back of the drill, thus concentrating the wax, always at the tip and guaranteeing lubrication during drilling.

• The wax melts with the use of the drill bit and improves cooling and removal of drilling debris
• When the wax runs out, the drill can continue to work. Only complete wear of the diamond indicates the end of drill life
• Recommended for the perfect finish of all types of ceramic floors
• For use with corded or cordless electric drills, always without a percator
