Hexagonal drill extension rods are a key component in a drill string, designed to increase the depth and reach of drilling operations. Their six-sided shape provides a secure, anti-slip connection that effectively transfers rotational torque and percussive energy from the drill rig to the drill bit, especially in tough conditions. Made from high-quality alloy steel, these rods are built to withstand the rigorous demands of deep drilling. They are widely used across multiple industries for a variety of tasks that require drilling in hard-to-reach or deep locations.
Hexagonal drill rod are produced by CNC machining and advanced heat treatment on the base of the same steel as Sandvik.
• Thread size: R22, R25, R28, SSR28, R32, SSR32, R35, SSR35, R38, T38, other.
• Rod size: Hex.22, Hex.25, Hex.28, Hex.32, Hex.35.
• Length: 2100mm to 6095mm.
• Carburizing process is applied to promote surface hardness, thus grant better wearing quality and lifespan for the drill rods;
• 23CrNi3Mo, which is in same league as Sandvik Sandbar 64, is applied as drill rod material.
• Cost-effective, good performance with reasonable price.
• Complete types of drill rod for various drilling scenarios.
Hexagonal drill extension rods are an essential tool in various industries, especially for applications that require drilling deep or in difficult-to-reach locations. Their hexagonal shape provides a superior grip and torque transmission compared to round rods, preventing slippage and ensuring efficient energy transfer from the drill rig to the bit.
These rods are widely used in conjunction with different types of drill bits, including spade bits, auger bits, and hole saws, to extend their reach. The primary applications include:
