Hey all, it’s me again, the HDD tooling guy from the factory.

I’ve been doing non-directional drilling (well, directional, but you know what I mean) for about five years now. I’ve seen some nice bore jobs and some that made me want to hide behind the mud tank. All the ugly stuff? Most of it? It starts with how people take care of their drill rods when they set them up.

So grab yourself a coffee (or an energy drink, no judgement) and let me share a few things I wish someone had told me when I was green.

For me the “click” moment was on a job in rocky clay.

We were pulling a 2” line back under a four lane highway. Everything seemed to be going well until – bang – the rod twisted off right at the box end. Lost the hole, lost the reamer, lost a whole day. The super was screaming. I was perspiring. Eventually we figured out the rookie (me) had over torqued the connection like a maniac because I thought “tight is strong”. No. And that’s how you stretch threads and make cracks you can’t see.

Now for the real talk:

Clean the fucking threads. All. Single Time.

I don’t care if it looks clean Wipe it off, brush it off, blow it out One grain of sand in there will gall your threads faster than you can say breakout torque. I keep a little wire brush in my back pocket all the time, like a toothbrush for my rods. My wife chuckles at me. My drillers don’t – because they never have stuck joints.

Don’t confuse families.

You got a box of rods from brand A and another box from brand B ? They may look the same. They are not. Different thread shapes Different shoulder angles Different steel Screw them together and you have a dog married to a cat. It will work for a time. Then there will be blood. Use one brand per string, or at least per size. Your back will thank you.

Lube is your friend. Use it, but don’t drown it.

I used to think, “more grease, better seal.” Wrong. Too much thread compound only serves to trap debris and hydraulics into the nose of the pin. Then you get fake torque readouts. A light coat on the pin threads and shoulder only. Like butter on toast, not icing on a cake.

Keep an eagle eye on your bend radius.

This one still hurts me. You’re in a long stretch of steer, the bore path is twisty, and the rods are flexing more than a gymnast. They can take it . . . to a point. But every time you bend beyond the recommended radius (usually somewhere in the 1.2-1.5 degree per 30ft range, check your spec) you’re work hardening the steel. The more you do that the more brittle the rod becomes Then one day, boom. Rule of thumb: if it smells fishy, it is fishy. Don’t make the rod into a banana. Back off, ream a pilot hole.

Breakout torque is just as important as make-up torque.

You know that time after you finish a pull when everyone just wants to go home? Don’t break the joints in the middle and leave them overnight. Moisture gets in, rusts up, and then the next morning, you need a cheater pipe and a prayer. Separate them off completely, clean them and store them off the ground. I mean off the ground, not on a pile of rocks. I’m serious. Sawhorses, old tyres, anything will do.

One more little story. Last year a customer called me pissed out of his mind that his new rods were “junk” because they kept getting stuck in the hole. I drove out and watched him make up a joint without wiping off the thread compound from the last rod, which was dried mud caked inside the box. I took ten seconds to notice it. He didn’t say sorry, but bought me lunch. That’s as good as an apology in the drilling world.

Look. I’m not trying to sell you the most expensive rods on the market. Trust what you will. But use them as the precision tools they are, not as crowbars. A little love before and after each shot will save you from that gut punch feeling when you hear “uh oh, we lost the string.”

Now go cut some clean bores. And, for the love of bentonite, clean your threads!

Have a horror story of your own? Hit reply – I have a dozen more and I love to swap war stories.
