The access hole in mine measures 17.5mm (a 10mm cap head bolt head is 16mm).
Out of curiosity I have just tried a (standard length?) 10mm drill in the hole and when it first touches the head of the 10mm cap head (with washer) it leaves just 35mm of shank protruding from the swingarm (coincidentally about the depth of the chuck of my drill) so, I don't think you'd need to worry too much about drilling too deep if you're just drilling the head off. Plus, there's enough room to drift the bolt out the nut-side if you remove the exhaust downpipe.
