What Is Drill Rod and Drill Rod Sizes?

What Is Drill Rod？

A drill rod, specifically a top hammer drill rod, is a specialized type of steel rod utilized in a variety of rock drilling applications. These applications span across several industries, including mining, tunneling, and construction. The drill rod is typically constructed from high-strength alloy steel, ensuring durability and efficiency in demanding conditions. It is available in a range of lengths and diameters, allowing it to cater to diverse drilling requirements. The versatility and strength of the top hammer drill rod make it an essential tool in these industries, providing the necessary support and functionality for effective and efficient rock drilling operations.

How is Drill Rod made?

Drill rod is typically manufactured from high-quality alloy steel. The process begins with the selection of the appropriate raw material, which is then heated and forged into the desired shape. After forging, the drill rod undergoes annealing, a process that involves heating and slow cooling to increase ductility and reduce hardness. The annealed drill rod is then machined to its final dimensions, which can involve turning, milling, drilling, or grinding operations. The machined drill rod is heat-treated to increase its hardness and strength. The final step is finishing, which can involve polishing or coating the drill rod to improve its appearance and resistance to corrosion.

Drill Rod Sizes

Drill rods come in different sizes and diameters depending on their intended use. According to the depth of the hole being drilled and the specific requirements of the drilling operation, different top hammer drill rod lengths are used in rock drilling applications. Longer drill rod sizes are typically used for deeper drilling applications, while shorter drill rod sizes are used for shallow holes. In most situations, the diameter of the drill rod for sale is 20mm~87mm, and the length is different from 260mm~6400mm.

In general, longer drill rods allow deeper drilling depths, but they also require more power and may be more difficult to handle because of their weight and length. On the other hand, shorter drill rods are easier to operate and require less power, but they are limited in the depth they can reach.  It should be noted that the specific application of different top hammer drill rod lengths may vary depending on the type of rock being drilled and the drilling conditions. The drill rod sizes and diameters can affect the drilling efficiency, stability, and cost. Therefore, selecting the right size and diameter of the drill rod is important to ensure the success of the drilling operation. Also, choosing reliable drill rod suppliers is crucial.
