The SHANDIKE T45 rock drifter rod is a solid medium-to-heavy top hammer drilling component. It works well on top hammer rigs and underground jumbos. Its diameter is slightly smaller than the T51, making it a go-to choice for drilling medium-sized blast holes in many operations.
Thread Standard: T45 – a 45mm trapezoidal thread that delivers good torque transfer and allows fast uncoupling.
Material: Made of 23CrNi3Mo alloy steel, which offers a good balance of strength, toughness, and wear resistance.
Heat Treatment: Full-body carburization or deep surface hardening, which improves fatigue life and thread wear resistance.
Profiles: Available in round (good for straight extension drilling) and hexagonal (stiffer, with better flushing clearance).
Flushing: A central hole runs through the rod, allowing high-pressure water or air to clear cuttings.
MF (Male/Female) Speed Rods: Male thread on one end and an integrated female coupling on the other. This design speeds up rod changes, improves hole straightness, and eliminates separate coupling sleeves.
MM (Male/Male) Extension Rods: Male threads on both ends, requiring an external coupling sleeve to connect rods.
Underground Tunneling: Used on multi-boom hydraulic jumbos for horizontal drifting and tunneling.
Production Mining: Suitable for long-hole drilling and sublevel stoping in underground mines.
Bench Drilling: Found in smaller open-pit mines, aggregate quarries, and civil construction sites.
Efficient Energy Transfer: Offers a good balance of stiffness and energy transmission, helping achieve faster penetration in hard rock.
Reduced Deviation: The rod’s rigidity keeps holes straighter and helps prevent the drill string from binding.
Cost Efficiency: The 23CrNi3Mo material combined with proper heat treatment reduces thread stripping and extends service life, lowering the overall cost per meter drilled.
