I tried on a drill press, does not work. The clamp cannot hold when I try to press the drill into hardwood

I gave this 3 stars because it is advertised, in part, that it works in a hand drill. It FITS on a hand drill but one is unable to apply the positive pressure, that a drill press gives, by hand without wiggling the bit.

Broke the clamping mechanism when I was attaching it to the drill press. Useless or poor casting. Lost $$$
