The selecting is not necessary, just state your start point in the code, I
had use A1. Try

Sub HideCols()
Dim iLastCol As Long
Dim iStartCol As Long

iLastCol = Cells(6, Columns.Count).End(xlToLeft).Column
iStartCol = iLastCol - 12
With Columns(iStartCol).Resize(, 6)
.Hidden = Not .Hidden
End With

End Sub
