The weight of diamond drill rods can vary depending on factors such as the length and diameter of the rod, as well as the specific material and design used in their construction. Typically, diamond drill rods are designed to be lightweight for ease of handling during drilling operations. The weight is often specified in terms of weight per unit length (e.g., kilograms per meter or pounds per foot).

As a general guideline:

Standard Exploration Core Drill Rods:
Commonly used diamond drill rods for mineral exploration, such as BQ, NQ, HQ, and PQ rods, may weigh around 1.5 to 3 kilograms per meter (0.5 to 1 pound per foot), depending on the specific size and design.

Thin-Wall Diamond Drill Rods:
Thin-wall diamond drill rods, used for obtaining larger core diameters with reduced material waste, may be lighter, typically ranging from 1 to 2 kilograms per meter (0.3 to 0.7 pounds per foot).

Specialized or Heavy-Duty Drill Rods:
In certain applications, such as deep drilling or challenging geological conditions, specialized or heavy-duty diamond drill rods may have a higher weight per unit length.
