Professional high-quality 60 twist drill pipe, 3m

The 60 twist drill pipe is a core component for deep-hole drilling, with a specification model of 60 (outer diameter, unit: mm) / 3 meters (single length). Its 3-meter length significantly upgrades deep operation adaptability: compared to 2-meter models, it reduces drill pipe joints by ~35% (greatly lowering leakage risks at connections) and fits 120-200m deep drilling scenarios—meeting demands for underground deep sampling and channel opening. The 60mm outer diameter maintains structural rigidity, adapting to complex deep strata like gravel-containing hard soil or moderately weathered rock. Weighing 31.3KG per unit, it balances deep drilling performance and deployability: it only needs small lifting tools (no reliance on large machinery), making it suitable for medium-sized mining sites or remote deep geological exploration areas with limited infrastructure. Its 205 flat iron specification (20mm width × 5mm thickness) further enhances structural strength and torsional resistance, pre…
