Review on ARES 70013 - 8-Piece S2 Steel Impact Driver Bit Set: Phillips 1-4 & Slotted 1/4-1/2 Inch - Premium S2 Steel Construction by Chad Baio

I bought these for an impact wrench to remove a slotted jackscrew which was really overwhelming and forced me to finish the job and wait til next weekend. After smearing the bolt with oil and continuing to hit it, one of those bits eventually loosened the bolt I was working on. BUT, the kicker occurs after the slot ends curve slightly, meaning it probably won't work again. For the money I was a bit disappointed but at least I can expect it to run once a piece on stubborn screws. I imagine the American workers of a long-gone industrial era looking at us and grinning at the fragile and fragile tools we use today.
