R28 Extension Rod

The extension drill rod plays a crucial role in connecting the drill bit to the rock drilling machine, enabling efficient drilling in a variety of rock and soil types.

Our drill rods are made from high-strength alloy steel and are available in both hexagonal and round configurations. Sandvik rods are carefully engineered to create straighter holes with minimal deviation, ensuring a longer service life.

Rod Shapes: Extension rods come in two main shapes—round and hexagonal. Hexagonal rods, known for their robustness and weight, excel in transferring energy efficiently and enhancing flushing during drilling. On the other hand, round rods are lighter and are commonly used in extension drilling applications.

Thread Varieties: There are two primary thread categories—R-thread and T-thread. R-thread options include R25, R28, R32, R38, and more, adhering to the fundamental dimensions and button profile specified in the industry standard ISO10208. T-thread variants comprise T38, T45, T51, and others, maintaining basic dimensions and button profile standards aligned with corporate requirements.
