seriously for the diy or a tech who doesnt see torx that much these things are top ****. i have only broken 1 t40 bit out of the set, when i did this i was trying to remove caliper stud's on an M5 ( there not supposed to come out). i also broke 3 SO gold torx t40 sockets trying to do the same thing. SO just broke off the tip when impacted with a 1/2" and my nieko socket exploded when hit with the 3/8ths !
i'm pretty set on SO at this point just wondering if i should grab some impact one's as well or solely the impact ones
