Hardstone Helical Boring Beam

Product Overview Hardstone Helical Boring Beam is a heavy-duty drilling component for hard rock drilling operations. It can be connected with Coupling Sleeve to form complete drill string assemblies, and it is compatible with Tapered Drilling Tools and Fully carburized taper drill rods. It can also be matched with Round Extension Drill Rod to meet different drilling depth requirements in hardstone construction. Key Advantages Made of premium alloy steel with precise heat treatment, this helical boring beam features excellent impact toughness and strong torsion resistance. The thickened helical thread structure realizes stable power transmission and reduces thread wear during repeated drilling. It can withstand continuous heavy loads in hard rock conditions, effectively lowering deformation risk and extending service life. Detailed Features High-precision thread manufacturing ensures tight fit and quick assembly. It can be combined with Round Extension Drill Rods for deep borehole cons…
