Last year we wrote about Swench “manual” impact wrenches — huge wrenches which store up energy via a spring-laded mechanism then release it suddenly to incredible effect — when a reader who used them on Navy nuclear-powered aircraft carriers tipped us off about them. The bad news was pricing: they start at around $600.
We noticed this morning, however, that Toolmonger reader PeterP posted a comment on our original Swench post offering his Model 750 for sale for $200.
The Model 750 delivers 800 ft-lbs of torque with a maximum handle pull of 50 lbs. It’s 18″ long and 2″ wide. Peter says he doesn’t have any of the sockets for it, but I’d imagine that’s something you could find.
At any rate, contact Peter if you’re interested or have questions.
