I'm not sure which model I have; I bought it maybe 10 years ago. Someone like my father (who had amazing skill) could grind a better point than the Drill Doctor, but for the rest of us I think it works quite well. The key to getting a good point is to ensure the bit is correctly aligned in the bit holder. There's a flat on the top of the bit holder, and the groove between the flutes must be 90 degrees to the flat, i.e., the flutes are at 6 and 12 o'clock and the grooves are at 3 and 9 o'clock. This is easy to set with a larger bit, especially using the alignment device on the Drill Doctor, but you need to take a little extra care with smaller bit. It only takes a few turns to freshen up a slightly dull bit, but for very dull bits, you will need to re-set the bit in the holder and repeat the sharpening process.
