Standard Coils

Using Drill Bits to Wrap Coils – Updated for 2015

How do you wrap the perfect coil? The best secret behind this is to wrap it around a drill bit so you can get maximum leverage and create the coils as close together as possible.

Some go for micro coils, some go for a nano coils. You can do either with a variety of drill bit sizes. You probably can’t go wrong with a 1/8 drill bit for starters and experiment from there.

Since a lot of guides and tutorials use millimeters to explain the inner diameter, here are some quick conversions of drill bits to millimeters (not exact conversions, just a general guideline).

3/64 = 1mm | 3/32 = 2mm | 1/8 = 3mn | 5/32 = 4mm

For my go-to setup I use a 1/8 drill bit with 28ga. Kanthal 5 or 6 wraps as a microcoil.

For an awesome list of various size bits, setups, and combinations see the coil chart / list below categorized by the kanthal gauge.

I would suggest either of these when you first start because they are very forgiving. Most of the time, as long as you get halfway […]
