Product description:
Integral drill steels/ rods are used by a hand held drill machine in underground mining and for small hole drilling, equipped with small power rock drills, like air leg rock drills, hand held rock drills, etc. It can reduces the expense of impact energy, improves the drilling speed and efficiency, also it can be used for drilling bore hole diameter from 30mm to 41mm usually. Regarding Integral drill steels,the quality of a steel material and a tungsten carbide is very important to get good drilling performance. Shank H22x108mm, H19x109mm, standard hex. Bit diameters include 20-42mm, According to different application, different lengths are available from 500mm to 10000mm usually.
Product features :It can reduces the expense of impact energy, improves the drilling speed and efficiency, also it can be used for drilling bore hole diameter from 30mm to 41mm usually. Each rods use premium quality alloy steel and excellent quality tungsten carbide to assure high drilling performance.
