Stratum Tapering Puncheon Shaft

Product Overview Stratum Tapering Puncheon Shaft belongs to Tapered Drilling Tools for rock drilling works. It can be connected by Coupling Sleeve to assemble integrated drill strings, and is compatible with Fully carburized taper drill rods. It can also be matched with Round Extension Drill Rod to meet varied drilling depth demands in complex stratum construction. Key Advantages Adopting high strength alloy steel and advanced heat treatment technology, this puncheon shaft boasts excellent impact toughness and strong bending resistance. Its optimized tapered structure ensures smooth impact energy transfer during rock breaking. It can sustain repeated heavy impact in unstable strata, lowering wear and deformation, and greatly improving the working continuity of drilling operations. Detailed Features Precision taper machining ensures close fit and fast on-site installation. It can cooperate with Round Extension Drill Rods for deep borehole drilling. Threaded Coupling Sleeve acts as the m…
