I've got cutting these down to a fine art now (if i say so myself). I've done that many of them that it can be done by eye and using the markings on the padlock themselves.
Invest in a micrometer, the depth gauge is very useful. But again, with the Abloys, they have a spring on the back of the barrel which needs to still act, so the depth you thought you could get away with will be wrong.
As for the cuts, I use a combination of a 3mm and 6mm bit. The main window is done with the 6mm and takes about 2 hours since there is 4 sweeps for every rotation. If you use say a 12mm bit, then the window will have seriously rounded edges in the corners and IMO looks like no effort has been put in.
You can measure where to cut central to the BB pathway by using the disc on the side to line the attachment up.
p.s Protecs & disclocks are different cuts to the classic and profile by about 4mm on the main window.... so make sure you measure every job before cutting.
