【Not Easy to Chip】Precision diamond particles and vacuum brazing technology ensure that the drill bit is not easy to chip or damage during the drilling process, guaranteeing work safety and efficiency.
【Machine】Suitable for hand drill, bench drill. Electric hand drill at 2000-5000RPM. The slower the RPM, the shorter the life.
【Highly advanced technology】By adopting high-end vacuum brazing technology, the diamond and the substrate bond closely and the service life is long and reliable, which is the ideal choice for your drilling work.
【Cooling and Heat Dissipation】6-10MM internal wax cooling wax, when drilling, the cooling wax melts to lubricate and cool the drilling surface; 20MM and above, the top of the drill bit has 4 U grooves, which is conducive to heat dissipation and discharge of debris.
