What a great little vise! I was looking for a small sized vise to clamp to my workbench and found this gem. It is compact but does the job perfectly. It is solid, made well, and finished well too. Most vises this size are fully painted, including the inside of the jaws used for clamping. This one has been finished, and as can be seen from the photos, is made well enough that there is perfect alignment between the jaws and no mis-alignment. I am looking forward to many years of use from this.Great find at a fair price.

It gets the job done but honestly if I was you I would use one that bolts down and one where the grip is textured, alright for small projects but awful for anything when you need to use a bit of force, i used a hammer to get this thing as tight as humanly possible and still couldnt get a solid grip. Still not bad for light duty work, And clamps pretty mich anywhere. For the price I couldnt ask for more

This vice just arrived, but I have already used it 3 times, once to repair an armature in a fan motor, 2nd to cut a bass guitar brass nut to size, and also to make a truss rod cover for that same bass guitar. I mount it to a little folding table I have in my bedroom, and it works out great. Makes those small projects a pleasure to do. It holds objects very snug. I also got this at a reduced cost because it was a return, with some sort of damage, but I found no damage and I saved a few bucks over retail cost because of that. Great bargain, great performing tool. Get one! Thanks. Kem. May 31, 2024.

Great working clamp for the money. Definitely worth it! I used for regripping golf clubs.

This little vice is a beast. For the price it may be unbeatable, if the jaw opening works for your project. Used it to clamp a rifle barrer/upper reciever block. I was able to push the opening up to over 3 inches, albeit it was probably hanging on by a literal thread, it locked shut for me. Holds like a champ. Handled the torque to remove factory barrel (+-70ft lbs). The barrel vise failed before this clamp did... I had used a mallet to tighten as much as possible. Slightly bent the tightening/loosening arm (insert technical term here)with the mallet, but clamp was solid. Weakest point would probably be the mounting base, but there are holes to more firmly mount with screws. Great product.

Nothing wrong with the quality, but be warned this is for very lightweight tasks. If you need to torque anything the vise will move on you. Not meant for anything that will hang over the edges. If you try to use anything that will hang over the edges, the vice doesn’t have enough strength to stabilize these items.

A sturdy, practical vise that can be clamped to a work surface, or secured by screws through the front casting.
