Drill rods compatible with the Vermeer D50×100 / D60×70
The D50×100 and D60×70 are heavy-class rigs running a 73 mm outside diameter rod with a 10 mm wall. Maximum torque rises to 16.000 Nm, more than two and a half times the 60,3 mm rod class. The same family also offers an 89 mm body rod rated at 18.000 Nm, shared with the D80×100.

Figures are taken from the master drill rod tables. Measuring the tool joint diameter of your existing rod with callipers is a surer check than the model code alone.
Why these figures matter
A 51 m bend radius and rod weights up to 78 kg make two things mandatory in this class: a site that allows a long entry ramp, and rod handling by crane or automatic loader. It is the standard class for long crossings under rivers and motorways.
STETON rigs in the same torque class
The 16.000 Nm torque class corresponds to the range these STETON rigs work in. If you are evaluating a new machine, this is the starting point for comparison.
Tooling that runs with the rods
About Vermeer D50×100 / D60×70 drill rods.
What is the difference between the 73 mm and 89 mm rod?
The 73 mm rod carries 16.000 Nm and the 89 mm rod 18.000 Nm, while the bend radius grows from 51 m to 72 m. The 89 mm is preferred on larger-diameter and longer crossings, but demands a wider entry angle and a larger site.
What reamer diameter suits this class?
Reamer diameter follows the product pipe, not the rod: the usual rule is a final reamed diameter of about 1,5 times the pipe outside diameter. The 16.000 Nm torque class supports large staged reaming.
How does rod weight affect handling?
A 4,5 m rod in 73 mm weighs 78 kg; one truckload of tooling is roughly 100 rods. Budget the rod box weight separately when planning transport.
