Rrough file = 20 teeth per inch.
Bastard file = 30 teeth per inch.
Second cut file = 40 teeth per inch.
Smooth file = 50-60 teeth per inch.
Dead smooth = 100 teeth per inch.
(Note- 1 inch = 2.5 cm = 25 mm).

20 teeth per 25 mm is rough file (because the teeth are arranged wide distance) so Bastard file (30 teeth per 25mm).
Second cut file (40 teeth per 25mm).
Smooth file (50 teeth per 25mm).
Dead smooth file (100 teeth per 25mm)( because the teeth are arranged with out distance).
