Yup!
Typically, on modern drums, max machine is .060 over stock. This gives you .030 for final wear. After that, the drum may work but, eventually, issues of the wheel cylinder working past design and heat build up from thinner drum material will be something to worry about amongst other things.
Except for some weird drums put on late 70's to mid 1980's GM trucks and SUV's and a few others, most all drums were done in even numbers. So if you have a 12" drum, max machine will be 12.060, discard 12.090.
Of course, I could be wrong about them little drums. Lately I've only been working with the 15" to 20" drums ( big trucks.) Tolerances might be greater for those smaller drums. I'd have to look up the specs on Monday.
Personally, if I had drums in the .060 to .090 range, I would go ahead and turn them. Especially since, generally, only .010 is removed. Considering that I would have a brand new set of shoes with max material on it and the brake wasn't seeing daily / constant use, I would feel comfortable with the setup.
Don't forget to lube the wear pads behind the shoe. Make sure they are smooth, too.
