Bedrock Tapering Octagonal Puncheon

  Product Overview Bedrock Tapering Octagonal Puncheon belongs to Tapered Drilling Tools for rock drilling operations. It can be connected by Coupling Sleeve to form drill strings, and works well with Fully carburized taper drill rods. It can also be assembled with Round Extension Drill Rod to meet diverse drilling depth demands in rock engineering. Key Advantages Made of high-strength alloy steel with strict heat treatment, this octagonal puncheon delivers excellent bending resistance and impact toughness. The octagonal cross-section provides stable torque transmission and improves rock breaking efficiency. It maintains stable performance under heavy impact in hard bedrock, reducing bending deformation and extending service life. Detailed Features Precise taper design ensures tight fit and quick installation. It can be combined with Round Extension Drill Rods to achieve deeper boreholes. Threaded Coupling Sleeve acts as the matched connector to link multiple drilling rods for flexible…
