Get a low Grip!
I am impressed! These are a must have, especially for hogging/roughing out large parts with little to hold on. I recently hard a large part shift which overloaded the endmill and needed a better solution. After checking with a local supplier, I found these less than 1/2 price and haven't looked back since. It will slightly mark full width 6061-T6 at 60 ft/position torque. Thank you Hass!

Awesome Jaws!
These jaws work great! Use the serrated tops for squaring your stock and and cutting most of your features. And you can use them like normal jaws as well. They came wrapped very well with tons of preservative oil as well.

Great Vise Jaws
Here’s what I liked about these, they are the perfect height, and they are priced right, they work like they should. Two things that I would have liked to see is the counterbore could have been cut a little deeper, because it seems like the 1/2-13 SHCS only has a few thousandths of clearance. The dovetail serrated section is a bit rougher than other brands, but otherwise the fit and finish is perfect. I would certainly buy these again.

Great Vice Jaws
Used these for the first time on a plastic part, worked very well for profiling. I also like that they are thinner than other serrated jaws that i have tried. The only think that i could see improvement in is having a set with replaceable teeth and options to hold round stock

Very useful tool
These jaws gripped confidently in un-prepped 304 true-bar. The smaller step was needed in my specific application, and has proven itself useful enough to became my standard 1st op holding method. I now have these for all of my name brand 6" vises

Great set of vice jaws
Very handy for holding onto just a small portion of the workpiece. Easily worth the price.

Work great
These work great for 1st ops and heavy roughing. Feels good knowing that part isn't coming out until I'm ready. Also nice to be able to bite into softer materials and slightly release to prevent bowing the part.

Great quality and price
These jaws have been great on delrin and UHMW parts. I prefer the standard height of these jaws vs. some of the competitors I have used and have been impressed with the overall quality.

fantastic jaws
these jaws provide great grip and hold on parts for fast material removal. we are using them to hold 17-4 stainless parts and have no issues with parts slipping out of the vise.

Worked exactly as I needed it to
Had to machine some UHMW and these worked perfectly keeping the pieces in place even during heavy cutting.

exceptional value jaws
Great value on some aggressive step jaws for your standard 6" vice perfect for agressive roughing passes

High quality at a low cost
These jaws are pretty sweet. Ive been cutting 304L with these jaws with pretty aggressive tool paths and haven't had any issues. Will definitely buy a few more sets for my shop and the one I manage for my day job.

Great Working Holding
These work great, allows you to hold on to only .100 and still not be afraid of getting aggressive with the tool paths.

Very satasified
We have several sets of these and recently added more. Just as good as any other more expensive brand ones we have used.

High Quality.
Excellent jaws that work perfect when you need max grip with a short hat. No need for parallels. We have purchased multiple sets of these and they are flat and indicate in within .0001" after swapping from the Kurt Jaws.

Work great, would recommend
Bought these to use in my super mini mill. They are harder than woodpecker lips and grip the material as you would hope. Definite good bang for the buck.

This Jaws Are Awesome
Excellent addition to any Kurt vice. These instantly helped increase productivity in one of our mills. The serrated profiles on these jaws are much better than other brands we've tried in the past.

Excellent Value!
These serrated jobs seem every bit as nice as some of the bigger name brands available and worked great for my needs. Definitely a great value and one I would recommend!
