I worked on a Schramm T450 (NOT Dual Rotary Drive) similar to this several years after I left Oilfield Drilling and started in Environmental Well Drilling. Coming from an Oilfield Background, I was pretty shocked to find out the Environmental Drillers were NOT allowed to use Rock Drill Oil (Air Hammer Oil) on Down Hole Percussion Drills -OR- Pipe Thread Dope on any of the Downhole Tooling. Why? The Geologists, Engineers, etc. didn't want to get any Petroleum based contamination down the hole. I think it is actually "Illegal' in some states when doing Environmental Work.
That's sure a company driller. Notice how he doesn't waste grease on the joints of a dry thread. It is a nice looking setup, though iv'e not used one before. 5 hours for a 125ft. hole your not making much money. If you would like to know how to do two hloes same place in the same time try and get ahold of me and ill come and show you. Different method but way faster.
Better than a DR!? Are you insane?😂 It’s just as good as a DR if you’ll never have the money to buy one maybe… if not you can everything in this video and more with a foremost. But if cost is the only issue sure by all means this system is the next best thing
