Correct, same principal. I find the BrakeQuip is faster and easier to use. The hinged clamp and shorter gripping blocks are improvements/ advantages, and the turret style punch is nice.
Again, there was not much room for improvement on the FedHill version, it is a fine tool. None the less I believe the BrakeQuip kit is an improvement.
As for price, to get a FedHill set equivalent to the small BrakeQuip model BQ351 you first purchase the $360 007C kit (out of stock at the moment) and add two more sizes for another $80,
Total of $440 for FedHill.
The equivalent BQ351 list price is about $240, and can be had for less.
The BrakeQuip kit saves you over $200!
