I've got a drill file that I need to change one of the drills on. Currently the line in the file is
T3C.05F107S55
which is tool 3 = 0.05 inch (1.27mm)
But what is the F107S55 relating to?
The part requires hole diameter 1.91 - 1.96 mm. Is 0.076 inch a valid drill size?

I came across another file which gave me some clues.
F107 is feed rate 107
S55 is speed 550 (rpm?)

Never seen that in a drill file before and I have written PCBCAD programs.
Is it something to do with GCODE ? which rout's PCB's ?
Usually drill machine just does it as fast as it can.
Unless its for a different material like an aluminium pcb ?

I don't recognize it as G code. But it could be a variant. The tool number is all my use requires for simple commands, only complex ones also require the size. I would expect tool number and drilling location. Speed is reused from a prior line and only needed when changing it. All of my program lines begin with G # which is what to do. G2 is make a hole. I only enter 02 the G is assumed by the first position in the code. I use G code almost daily for my sheet metal punch. It is all numbers.

Its probably some extended version of NC drill file with extra functions.
The drill files I wrote code for are very simple. Just drill sizes at top then a list of coordinates for drill sizes and hole positions.

Yes, the file did not list the drills at the start, they are listed like that at the tool change lines. Not sure what package it was generated from. I found out that the fabricator uses metric drills so just needed to list exact imperial conversion.
