Coil Winder
This compact aluminum cylinder stores four different sized bits in its handle, and four different guide holes for the ultimate in precision winding. Wrap perfect microcoils every single time without the hassle of multiple drill bits, rewrapping imperfect coils, or other headaches. Also an awesome option for smaller gauge parallel wraps.
This thing isn't quite an automatic coil machine, but it's close. These are what we use for wrapping coils in the shop.
