I would say it's the opposite of let the tool do the work. Good catch phrase, but in this case you have to fight the rotation, or readjust. Tip loading, or a twist that allows the metal to get between and spread the blades apart is what causes this to happen. I think of the tool doing the work as stepping back and letting things break when they do. It could read "let the tool do the work until it starts to spin" and readjust.
Yes, that's a good way to explain it when it comes to these Hurst edraulics. I don't have experience outside of Hurst. If they move off plane a little, they will be fine. I fight the roll, and if it looks like it's going to beat me, I readjust.
Thanks, I too have very limited expirience outside of hurst, and for some odd reason, the VFD that I am with ( which from 2017-2023 ran avg of 30-50 entrapment calls) has run ONE pin job since I started, and I wasnt even there. Needless to say, my knowledge is still limited to a few training cars.
This is incorrect. You don’t and can’t “fight the rotation” of 10,000+ PSI — reposition and get a deeper bite where the tool is designed to cut and you will limit roll.
we even teach removing your support hand after attaining a purchase.
Are you talking about cutters or spreaders? Attaining a purchase sounds like a spreader situation which I agree with you on.
You can absolutely fight the rotation, which will get it to puncture and bring lighter metals deeper in. Sometimes you lose, and need to readjust. Your rated psi numbers are not what you are fighting, you are coaxing the tool to assist the puncture. Try it next time you train on them.
What year is that Altima? Any idea? I’ve broken a hydraulic pair on a newer Jetta. Haven’t with our battery hurst tools yet but a neighboring company broke and snapped their cutter just like that on a newer vehicle. Rep for hurst said sometimes they can’t cut through the boron steel/newer parts of it. Not sure what gen that is either but that’s a factor too. That was a couple years ago and was probbly first or second gen batter hurst so I know they have an even newer and updated generation that’s capable of cutting through with an even higher psi now
Yah, that's what I was thinking too... not enough purchase to get the tool deep enough to be as close as possible to the base, thereby only cutting with the tips. Either that, or cutting the Nader pin thinking it was the hinge?
Also happens when you see the shears start spreading themselves apart. If they’re not cutting and start flexing in the wrong direction, it’s time to stop and try something else.

You hurt the Hurst!
What were you cutting??
