I'm puzzled by one small twist drill bit. It is much more aggressive than any of my others. It often runs off without me going too deep. Sometimes I can't pull it out on the forward setting and it pulls out of my drill. What did i buy?

What does the tip look like under magnification.
If you can do and post some pics that might get the answer quicker.

Off Topic: I recently saw Colorado Springs in a rail doco, nice looking place.
I'm guessing the back clearance angle is too steep; I've found that varying that angle tends to affect how aggressive the bit is.
