CASOMAN 1/2" Drive Master Impact Hex Bit Set, Hex Driver, SAE/Metric, 1/4" - 3/4", 6mm - 19mm, Cr-Mo Steel,Impact Grade, One-Piece Construction, 20-Piece 1/2" Drive Allen Bit Socket Set

I could have went with snap-on or MAC but this set is for work and tools tend to get very dirty, lost or stolen in the plant, so I don't take my name brand tools to work. These do exactly what I need them to do and cover all the sizes I ever come across. I used the 1/4" today and it worked perfect, no slipping, no twisting and fastener broke loose and was reinstalled with no issues. Why spend more for the name brand sets when you can get this one for and 1/8th of the price and will do the same job, plus you get a case with both metric and standard in it. Like all cases I wish the latches were a little better because in time the will both break, then I'll just slip a rubber band over the case to keep it closed lol. Great value especially for the low price.

I was a bit nervous using the air gun on these but they hold up well, none have cracked or broke on me, for the price you cannot go wrong, I've bought a few other impact sets from casoman, for the price it is comparable with bigger brands. The length is nice, I use these on caliber bolts for the most part, love them. I'd recommend.

I needed these to move a 5/16 plug for the gearbox track drive on my Kubota excavator. Gotta change the 80/90 gear oil every 500 hours, and the plug did not want to come out. Broke a standard hex allen wrench trying to remove these plugs. They popped out with these wrenches attached to my Bosch impact driver.

Have not used them yet. but I don't see how I could go wrong or get better value anywhere else. Highly Recomeneded!!

I bought these to do those pesky sway bar end links, where the end of the stud has a hex key hole you need to hold while turning the 18mm nut. I wanted to hold the nut and spin the stud with an impact. The hex needed was the smallest in the kit, 6mm. Because of rust and crud I needed to hammer in the bit, heat up the nut, then hit the hex bit with the impact. After all the hammering, torching and impact for 4 of these joints, the bit still looks like new. No damage at all. If the smallest of these bits can take this punisment I'm sure all the bigger ones will last too. For the money - you can't go wrong on this set.
