SP Air CorporationAirSP-7730 3/8" Reaction Free High Speed Impact RATCHET Discontinued Replacement SP-7730-V2

seems to be built sturdy. BUT!!!!!!!!! only 60 lbs of torque. oiled up with 120 lbs of pressure takes 5 seconds to loosen a bolt at 60 lbs. i have a harbor freight impact 3/8 ratchet (crap) and it only hits at about 40 lbs. why do they all lie so much. i might send it back and see if i got a bad one. if it would hit at 80 lbs i would be happyMORE ON THIS RATCHET!!!! so i returned it and got a refund ok, no problems. so i ordered another one to see if maybe i got a bad one. nope!!!! same crap only 60 lbs of loosening power. not 100. i wont get another sp. why do they all lie just say what the real torque is!!!!!!!

Right out of the box, the wrench would reverse direction on it's own when driving a fastener. After a couple of weeks and tightening and loosening *maybe* 600, 3/8" anti-seized bolts, this wrench won't engage anymore. Will not buy one again.

The air-ratchet of true awesomness. It's a bit on the loud side, and it's not the smallest or lightest air ratchet I've ever used.But heck, it is by far the highest torque. The spec is 100ft-lbs. It's good for every bit of that (and I suspect considerably more). This doesn't seem to come at the expense of being a low-RPM tool - it's as quick as my Blue-Point and Ingersoll-Rand ratchets if not quicker.Having bought a new tool, testing was necessary. The test was running an property class 8 M10 nyloc nut down an 8.8 property class bolt. I held the trigger down at the end, and watched it hammer away for ten seconds until it had stripped the thread out of the nut and the bottom of the bolt. This is not something I would expect an air ratchet to be capable of. Frankly, they're normally a bit disappointing in the torque department if you're used to an impact gun. Not in this case though....It's massively more torquey than my 1/2" Ingersoll-Rand ratchet 1111A.I suspect it will do fasteners that I'd previously have had to use my big 1/2" impact gun on. I haven't tried undoing wheel bolts with it, but I harbour a suspicion that it will manage to do them.The reactionless thing - well, more or less. You do have to hang on to it a bit, compared to my IR 1111A 'knuckle-saver' reactionless ratchet I bought ten years ago, or a conventional impact gun (or IR Hammerhead). For all that, it's a hundred times easier to hang on to than a conventional air ratchet.Glad I bought this. Expensive, but very, very effective.

the internal action works oddly and has a lot of vibration and chatter. works well the trigger is pulsed under load. likely i wouldn't buy again but i do like the torque output and clutch system that keeps your knuckles safe

Purchased and internal pin broke within one week. Had repaired but now it will not consistently ratchet. Another reviewer reported needing to pulse the throttle. I experienced the same thing. It makes a lot of heat in the head and smells like burning metal. I think the high free speed does internal damage. The impacting is phenomenal though, once the fastener is pulsed down.
