No water, all dry dozen, cooling wax, hand drill available
Cooling wax filling full, wax showing silver-white, drill body blue bright, diamond brazing bit, marking line more clear
Cooling wax filling full wax showing silver-white drill body blue bright drill bit brazing carborundum line marking more clearly
New upgrade of internal cooling wax without water, high-performance cooling wax, effective heat transfer, heat conduction fast/perfusion volume large/durable, open 30 holes can be used
New upgraded cooling groove for cutting edge chip removal, design of spiral chip removal groove for cutter head, upgrade large capacity self-cooling groove with fast chip removal, large chip removal and good self-cooling effect
Durable, the measured drilling ceramic tile open 60 holes without pressure, different drilling material, different number of openings, the higher the speed, the more the number of openings, the recommended speed of more than 2600 rpm, 6 mm/1 cm thick ceramic tile/open 60 holes
Operation Method: the drill and electric drill correctly connected and fastened, the drill bit drilling surface perpendicular to the drill surface, electric drill acceleration, can slightly shake auxiliary debris, pay attention to the higher speed is not easy to skid
Advantages of drilling: drilling quickly, can open the hole blind hole, chip removal smooth, good self-cooling effect, suitable for a variety of common requirements for opening
