BE CAREFUL... you can burn your nail and make a hole REAL EASY.
I did most all my customers by HAND and was just as fast as the drill girls and the customers liked it better. if you use a heavy coarse grate CURVED file first and the do the fill and then medium and then fine and then BUFF (all these last ones you can get on a 3 or 4 way buffer file.
One of the BEST files is the CURVED ZEBRA file. You know it because its CURVED and lookes like a zebra. With one of the curved zebras and a fine file and buff you can do nails REALLY fast.
