Perfect for Coil Wrapping
This device makes it super easy to build near perfect coils. It's failproof in my opinion. I've used it for 24 and 28 Gauge wire so far. There are three different size bit attachments to accommodate whatever wire or build you are using. You can also mount your 510 RBA/RDA or whatever tank on the device while you build. Very nice gadget and well worth the price.
