Review on Noga 99 001 019 NogaFlex Holder NF1018: A Versatile and Sturdy Tool Holder by Dan Bobbert

This is the ideal holder for quickly setting up parts on a milling or drilling machine. Just slip it into a drill chuck or collet and a knob allows you to loosen and set anywhere. No more fiddling with screws and hinges to find the right angles, it's just faster. It is heavier and less stiff than other holders. I wouldn't trust him with more than a few thousand in a horizontal spindle.
