I noted this with Martins more than any other bow. Oxidation. Had the screw broke loose you would have smelled something like sulfur.
I have never had problems drilling, but not a wise choice either. A bit too much and....
What I have done is used a dremel and thin cutoff wheel to grind a screw slot wide enough for a big screw driver or to use a center punch to drive the screw loose as you would turning the screw.
If anything I'd contact Martin. You could then send the cams to Martin and shipping would be far cheaper. And definitely insure the cams, so while on the phone with Martin ask what the cams would cost. Me, if I didn't ask for cost, insure for no less than $200.00.
Thanks for the reply Sonny. Fortunately in the time it took to right my post, the Toolmaker got them out using a carbide end mill in a bridgeport. He bored through the screw head and unscrewed what was left with a vice grip. He said they were loctited in and I'd never had gotten them out. Well, I'm starting to feel the love again! Got my Lizard tongue rest over the weekend so now I have to source a sight and scope and stabilzer and I'll be ready to shoot.
For what it's worth, I used my DeWalt impact driver.... I went to my local machine supply store and got an Allen bit that fit the mod screws, put it in my magnetic impact bit doohickey and voila!
If you're going to do this, exercise some care... I was very gentle while dong this and it worked great.
After I got the screws out I cleaned the threads in the mods and REPLACED the screws... I also have a backup set in my tackle box.
Hope this helps!
Thanks for the info........seems like this is a very common problem. I'm just happy that they are sitting on my desk with new screws finger tight (For now) in them. I'm fortunate to have a complete machine shop at my disposal. It looks to me as though the screws Martin uses are hardened. Probably with the intent that the hexes won't strip out.

When using either, I make sure to get some on the threads as well as the underside of the head. I've had a couple module screws that were bound up due to the head being galled onto the module. The threads were plenty loose once I got the heads off. I drilled mine out as well.

Yeah, I know I'm grumpy and opinionated.
I have yet to see hardened mod screws. Perhaps the previous owner put in heat treated screws.
Another tip, use other brand screws that have larger allen holes. Had a FireCat that I replaced the screws with Pearson screws. Worked great.....
Great idea Sonny!
