Compatibility Notice
To ensure optimal performance and longevity of your drill rods,
ROSCHEN recommends using only ROSCHEN manufactured rods within each
drill string. While rods from other manufacturers may appear
similar in material, thread design, or manufacturing process,
variations in dimensions and tolerances may affect compatibility
and could lead to reduced performance or premature wear.
