I'm in the planning stages of building a CNC hotwire machine to cut out Radio Controlled aircraft parts and I have a stepper motor question. I found some stepper motors for a good price and was wondering if they would work. Here's the info off the sticker on the back of the motors...

Astrosyn Miniangle Stepper
p/n HM000310000
AST TYPE 23LM-k055-01
NO. H1524
3.4 V/Phase
2.1 A/Phase
1.8 Deg/Step
Minebea Co., LTD

If these are not what I need, what should I be looking for?

Thank you
