Best way to drill leather?
 
Fitting a new leather interior and need to drill some fixing holes through it.
I am worried about drilling it in case the drill bit catches the leather and pulls it. I can't use a punch as the way it is made a punch probably will damage the GRP underneath.
Does anyone have any bright ideas?

how about a medical punch? something like this:

There might even be a saw-toothed style version too, for the bigger sizes, which should allow even better control while spinning it, and hopefully shouldnt do much damage to the grp.

Without seeing the application and knowing the size of hole/s you're creating, it is difficult to advise but a slow spiral drill will be less likely to snatch I would think and it is also good for drilling plastic/fibreglass afterwards...
Could you not just abrade a hole in the leather with a Dremmel and suitable cutting tool like a burr?
Also, you could always use an old fashioned hand drill for more control but then you would have no hands to keep the leather flat and tight whilst drilling.

How about one of these?

Or can you slide a thin piece of steel to protect between the leather and GRP and just use a punch/hammer?

If the holes are not too large and near the edge of the material then this may do the trick. I have used one for several years. Peter.
