This integral drill steel is suitable to drill holes with a small diameter. Given that this drill steel’s head is equipped with tungsten carbide, it can drill rocks with no need to be connected with tapered drill bits. This is why this integral drill steel is an ideal alternative to tapered rods and tapered chisel bits.
