This might help, taken from the RPM file found in the Predator Software folder under "Program Files".
The "H" is the tool height, the rest are as follows:-
Also these are from a Post mProcessor line 110:-
110. Tool list format.
"DIAM_OFFSET ",list_tool_number,"= ",
That would make your (MTOOL T4 S4 D0.063 C0. A135. H5.) =
S4 D0.063 = Drill with a diameter of 0.063
C0. = No corner rad
A135. = Drill point angle is 135 degrees
H5. = Tool length 5 inches
Hope that helps
