Definitely the best

Easy to use and super strong. Was exactly what I was looking for. Built for a life time of strength.

Thank you for your review James. We hope they last for generations!

Awesome product and awesome folks to work with.

Thank you for your review. We love working with our customers!
This apparently graduates from engineering to some kind of magic...

These clamps are unbelievable. They put brute force and fine adjustability in the same tool, which is unheard of. The grip face is a brass block that swivels so you can switch between a flat face or two different serrated faces. These things are truly remarkable, and they apply to work all over the shop.

I wish I'd had a pair of these brutes twenty years ago. You will save money by buying two of these, and save room in your shop when you don't need a dozen other kinds of clamps. Truly ingenious.

Thank you for your review George. Our goal is always to create something magical through great engineering!
Much stouter than Kant-Twist

These are really stout... heavy duty clamps. The gauge steel is almost 2 times heavier than the Kant-twist clamps. I’m impressed with the design and quality of craftsmanship of these clamps.
That said, they are also more expensive than the Kant Twist clamps but the Dimide clamps do have their place in the shop IMO.
It’s kind of like comparing Bessey clamps to Jorgensen clamps. Both good quality but I’d prefer using the Bessey every time. Same here....like the Kant-Twist but prefer the Dimide.

Thank you for your review Tim. We hope the clamps have a place in your shop for decades to come! -Emmet, Co-Founder
Revolutionarly Breakthrough for Clamping Metal

This clamp is a revolutionary breakthrough for clamping metal. It has turned my clamping experience from drudgery to ease, because I can drive the clamp screw with my variable-speed impact wrench, instead of depending upon my own strength. (The design of this clamp enables an impact wrench to ease the clamping process, just as it has eased the loosening of rusted-on lug nuts.) I can now obtain huge clamping forces with very little effort. For example, by holding the clamp in one gloved hand and the impact wrench in the other, I snuggle the clamp down upon the work. Then I make adjustments, and finally I clamp down hard with the impact wrench. Releasing the clamp with the impact wrench is just as easy. In this way, I have operated the clamp all day, four days in a row, with very little stress.
The clamp comes with a T-handle for manual operation. I found the T-handle useful when clamping pipes, where fine adjustment is needed to fit the pipes into the V-grooves. After making this adjustment, I remove the T-handle and clamp down hard. I remember struggling with manual clamps to tighten down a metal work-piece to the table of a drill press or a milling machine. Thanks to this new clamp and my impact wrench, those struggles are over!
Once while tightening, I got careless and let the impact wrench slip off the clamp; but there was no harm or damage done. This clamp is well-made, and I found it to be safe and forgiving to use, provided I wear gloves and I remove the T-handle before applying the impact wrench. A safety-stop prevents my being pinched between the main hinge and the screw. Also, wearing gloves avoids my being scuffed by the mechanism. I am excited about this clamp, and I would recommend it to anyone who clamps metal.
