This JH Williams CC-410C 10" clamp is exactly what I was hoping for. I used this to attach a milling vise to a drill table. With a competitor's clamp, my vise wobbled and shook. However, this clamp from JH Williams allowed the vise to be securely fastened to the table without movement. The resilience was excellent. There are no rough edges to snap on. everything smooth as it should be. I will definitely buy more in the same size. Pros: * Deep groove (Perfect for my application; drill press table) * High clamping force (enough clamping force to attach a router vise to the drill press table while simultaneously cutting out pieces of aluminum with the end mill) * Copper screw/handle (comes in handy for spatter when I'm using it use for welding) *Made in USA
