Glad it worked.
I initially ordered this because I thought 1mm was small enough. Tamiya Craft Tools Item 74049... https://www.amazon.com/dp/B000BQWM0E?ref=ppx_pop_mob_ap_share I was wrong. It was still big.
So I ordered this yesterday.
Tamiya 74044 Fine Drill Set https://www.amazon.com/dp/B000J49X9Q/ref=cm_sw_r_cp_api_glt_fabc_J7T32DQDH9CDSJ2JFQZR
I am quite positive one of these drills will work.
I know there are many other drills that are cheaper but I just like Tamiya’s quality. Throughout my experience, I learned not to go cheap with tools. I’ll either pay with time (takes longer to do the job) or failure of the job and have to do it over.
I paid about 17 bucks each so the price you see on Amazon now is quite overpriced.
Edit: the first drill set has 1mm, 1.5mm, 2mm, 2.5mm, and 3mm. The second set comes with 0.3mm, 0.4mm, 0.5mm, 0.6mm, and 0.8mm
Just yesterday I ordered this drill bit set.

I comes a 1mm, 1.5mm, 2mm, 2.5mm, and 3mm drill bit. Perfect for all your barrel drilling and smaller (think infantry) magnetization needs.
I also picked up one of these to drive them.
