Bought as a set a month ago, punches look good and strong. One of the stamps has come loose from the knurled end and falls off easily. Wouldn't buy again, maybe buy a shorter set.
I used them to rebuild the rear (GM 8.6 10 bolt) and front (GM 8.25IFS) diffs. After a while, the two largest punches started bending in the middle, and the third largest actually popped out of the grip. They've done their job but are pretty fried now.
Bought for frequent use. They were light, had good length and seemed strong, but after a few hits on the UTV transmission pin, they buckled. I also couldn't get as much power as I could get from my steel roosters. They're not bad for light duty and the price, but if you pound them hard, these aren't them.
