I've used and abused my Craftsman 6" HD Vise for the past 10 years and it has never failed me. Initially I found too much play in the opening\closing cam action, but quickly remedied that by tightening the main swivel bolt that was 2 threads loose. Since then, this vise has helped me hand threaded 2" pipe, has supported multiple large woodworking projects for construction and assembly fabrication, drill large 1\2" plate steel and hammer into submission rebar and angled steel with my shop 5# double head sledge.
I find the 6" vise has a large opening capacity, holds objects tightly and releases with ease. It isn't designed for industrial use, but then it only comes in at 10-20% of the commercial vise $$$ market! Yep, it's easily handles all of my DIY projects and has been an Outstanding supportive unit for my homeowner construction-fabrication-maintenance needs!
The main control arm was not straight,to make the vise level reqired bolting the vise at an angle.Lastly it was not made the the U.S.A. which was not indicated on the box it came in or on the product.
Bought the Craftsman 6” vise because the one at home didn’t have a large enough throat. Very happy with the price and quality of the vise. Had accumulated some points and were able to apply them to the purchase.
This is an excellent vise, especially for the price you're paying... I bought 2 of them. Id recommended this vise to anyone, had mine shipped to the store and picked it up in no time. It's heavy and well made.
