Integral drill rods are ideal in small hole drilling, all integral drill rods consist of Hex. rods with integrated cemented carbide chisel-shaped bit heads.
Integral drill rods are ideal in small hole drilling, all integral drill rods consist of Hex. rods with integrated cemented carbide chisel-shaped bit heads. With the same steels as Sandvik and best carbides made in China, we are supplying different lengths of integral drill rods with different head diameters.
Carburizing process is applied to promote surface hardness, thus grant better wearing quality and lifespan for the drill rods;
23CrNi3Mo, which is in same league as Sandvik Sandbar 64, is applied as drill rod material.
Cost-effective, good performance with reasonable price.
Complete types of drill rod for various drilling scenarios.
Drilling duties in tunneling, construction, mining, quarrying, etc.
