Robin,
Use some cutting fluid if you have some - if not use some oil - any oil will do better than nothing.
Because the material is 3/8" thick using just two taps will do the job fine, but always start with the 1st tap - the one with 1 line. Depending how far you go down with this tap will allow you to use either the 2nd tap (the one with 2 lines) or you may be able to go straight to the final tap - the one with no line.
Do use some cutting fluid - it does help
And do clean the tap after each and every use
