Mayhew Tools 32029 Pneumatic Bolt Breaker - 2 piece set - TEST PART 2 

It's so weird because I've used shake n breaks to solve VERY stubborn bolt/screw situations before. I remember back to what my dad taught me about about hammering things. The size of your hammer dictates the characteristics of the impact. Sometimes, a small hammer does a better job than a large one. I have a dialed pressure regulator on the bottom of my air hammer now, and when I'm working on stuck bolts it's often smaller ones in tough places - which is why I'm resorting to such methods in the first place. I often dial my air hammer way down, and I've found that low settings work great for a lot of shake-and-break situations. In most cases, I could rest my hand on the wrench, and it would come out. I haven't tried larger bolts many times, but my IR air hammer is hot as hell and works great. Things like 5/8 countersunk bolts with 3/8 allen key fittings, for the teeth on bobcat skid steer dirt buckets. The shake and break often times saves me from having to weld and/or drill/extract a bolt. I like your scientific mind, but doubt your conclusions drawn in this video. I bet if you put 125 ft/lbs of torque on that wrench, it'd work (duh, lol). But what about 100? or 25? The shake and break is designed to pulverize corrosion in the threads of stuck fittings. NOT make it unscrew something. If you over do it, it will distort the threads. Long story short, try to take out an 80's jeep door hinge phillips head without one of these. then try it with. That's what it's designed to do. Not magically produce torque.

It seems it's more usefull for rusty bolts you're worried about breaking I've used an airhammer and box wrench at the same time and worked great without breaking a single bolt I don't see this wouldn't do the same

Its meant to break rust not perfect normal bolts. Of course and impact gun in this situation will work better

In the video it didn’t seem as though you were trying to turn wrench while hammering. They are only designed to hammer the bolt while you use the wrench to turn it.

It's not meant to just turn it off with just the air hammer. It's designed for rusted and stuck bolts. You have to put pressure on the wrench at the same time you are hammering on it with the air hammer. It'll rattle the rust and corrosion loose.

My air hammer is impossible to control with one hand the way you do in this video. If you’re able to easily control the hammer with one hand, I have to wonder how hard the hammer is actually hitting.

that doesnt make sense if you can break the bolt just by hand but not using the shake and break pluse your hand....
