I have a lot of deepwell impact sockets from Harbor. Three of their torque wrenchs. I have used them a lot.
Have yet to brake one. I had the whole drive train out of the Jeep above. Never fased them.
The panheard bar on the back has a hudge torx bolt in it. I never could break the one up in the frame with my 3/4 breaker bar and a harbor freight torx. It had rubber bushings and was tight, so I left it hanging. (Need it looses to wiggle tail pipe up in there since I only had it on stands)
Note, I only do this as a hobby. Sure snapon it best there. They show up to replace there stuff.

 

I brought all my S-K tools while working at a indy auto parts store. That was over 40 years ago and they all still work well.

 

I a big believer of you get what you pay for. but there are some tools that I will always go the cheap route. Phillips, straight head, torqs, star, ill go the cheap route all the way, I would prefer that they break over the bolt head being damaged. everything else, Im willing to pay $$$ for.

 

 

 

My $0.02: The problem with Torx stuff is mostly in how it's used. The official spec for a T20 fastener, for example, is a maximum torque load of about 9 lb-ft. There are lots of times when a Torx head screw gets some corrosion or other gunk locking it in and it takes way more than the spec torque to break it free. In that way, even if the bit you are using meets or exceeds specs, you can break it.

Don't like them in an environment where corrosion is likely.

As for tool brands, haven't found one that's any more reliable than any other for the small Torx stuff. I've twisted or broken every one of them, including the premium brands.

So far, the set of Tekton bits I picked up a couple of years ago seems to be holding up better than average.

 

Hate to burst the "Snap on tools don't break" myth, but I've broken plenty of Snappy, Mac, Matco etc. in my years as a wrench thrower. Even locked up many a "Truck Brand" air-tool, but I can say I've never locked up an Ingersoll Rand air tool, built like a proverbial tank.
My 1/2" IR impact hasn't missed a beat in 25 years, It's one of the first tools I ever bought.

All tools will break, they all have their limitations. Yes, some tools are absolutely built to better specs than others, but even the best have their limits, and most tools I've seen break were being asked to do something they weren't designed to do.

Worked in my dad's shop in the late seventies. I still have my Mac tool boxes filled with Mac and Snap on tools. If I had to replace what I have in there today 30k would not be a too far off. Glad I bought quality tools back then.
