          Your problem is you are probably using an impact driver numbers vs impact wrench. Even compact battery impact wrenches can get over 300 ft-lbs of breakaway torque. The beefiest consumer cordless can get over 1000. That’ll rip those lug nuts right off.

              Ha, I haven’t seen these, the Torque Test Channel needs one!

              Looks like a standard drill/driver with a torque multiplier bolted to it. I wonder what that does to the impact force?

              The harder the hit the better generally, but cordless sometimes substitutes speed of hits, these multipliers would slow that way down.

                They have a huge lineup of tools, some corded, some air, and then the battery lineup. Probably something for everyone.

                I think at those torque levels the hit of impact doesn’t matter, because its not doing an impact to try to torque a resistive nut, there will be a bracket that touches the workpiece to resist the 11000 counter torque.

                  I also wonder what kind of bolts will need that amount of torque to tighten or loosen. They use much heavier impacts on train tracks (even gas powered ones with shoulder harnesses).

                  It would seem like when torquing things that large that bars and multipliers would still be the most accurate. But there must be a need for this kind of tool.

                    Some of their models are super accurate for aviation etc, and have PC connection so you can feed bolt torqure values back to your inspection reports. The planetary gearing reduction seems to mean you don’t need to lug around giant bars and mutlipliers. But what needs 11000 ftlbs?? Ships maybe?
