Kant Twist 411 Quick Acting Hold Down Clamp Without Base Plate, 3" Holding Size, 2-1/4" Length x 2-11/16" Width, 1500 lbs Holding Capacity

Good holding force on a drill press with t-slots.Has adequate reach and height for most projects.Heavy and sturdy.Could possibly be used on a fabricating/welding table.

These are just OK. The bolts that attach the base plate to the clamp are over-long and need to be ground down for the base to rest flat on any surface, or you'll need to add washers on top to keep them from poking out. Pretty poor thinking there, for a $30 clamp. Also, the bolt used for the hold down is just a socket head screw that is not long enough to use with most drill presses, so you'll probably need to find another. Also, it's just loose and flopping around in there, so it will spin without an allen wrench to counter-tighten which is a PITA. All in all not useful without modifications. I went and bought some 3/8" x 2" bolts and welded them to the base then got some wing-nut type nut for tightening from below. NOW the clamp is useful for me. Once setup right these are fantastic clamps for a drill press (how I use them).

Thanks Is very fast and good comunicatio. AAA++++

Great little clamps, very well made.
