Method of selecting drill rods for rock drills

Date: Feb. 28, 2024

When selecting drill rods for rock drills, it is important to consider factors such as the type of rock being drilled, the length of the hole required, and the drilling equipment being used. Here are some general steps to follow:

1. Determine the rock type: Different types of rock have different hardness levels and will require different drill rods. For example, softer rocks such as sandstone may require a lighter and faster rod than a harder rock such as granite.

2. Determine the hole length: The length of the hole required will determine the length of the drill rod needed. Longer holes will require longer drill rods.

3. Determine the drilling equipment: Different drilling equipment may require different types of drill rods. For example, some rock drills may require tapered drill rods while others may require threaded drill rods.

4. Consider the environment: Consider any environmental factors that may affect the drilling process. For example, if drilling in a wet environment, PTFE-coated drill rods may be necessary to prevent rust and corrosion.

5. Consider the cost: Finally, it is important to consider the cost of the drill rods. More expensive drill rods may provide better performance or durability, but may not be necessary for all applications.

By considering these factors, you can select the optimal drill rods for your rock drilling application.
