This JH Williams CC-410C 10-Inch clamp is exactly what I was hoping it'd be. I used this to secure a milling vise to a drill press table. With a clamp from a competitor, my vise was wobbling and shaking all over. However, this JH Williams clamp allowed the vise to be securely affixed to the table without any movement. The clamping force was excellent. There are no rough edges to clamp... everything is smooth as it should be. I'll definitely be buying a few more of these in different sizes.Pros:* Deep throat (worked perfectly for my application; drill press table)* High clamping force (Enough clamping force to secure a milling vise to a drill press table, all while hogging out chunks of aluminum with an endmill)* Copper screw / handle (Will come in handy with regards to splatter when I use this for welding projects)* Made in USA
