Most common drill bits are of the twist bit variety and are so called because the flutes on the bit twist around and up the bit. Left-handed drill bits were once used when it was easier to change the drill bit than it was to change the rotation of the drill. Left-handed drill bits are available in many different sizes and lengths, but their limited use can make them difficult to find. General-use twist bits are the most common form of left-handed drill bit, but some have flatted shanks to prevent twisting in the drill chuck.
Fasteners that have broken off in a threaded hole can be a time-consuming problem to repair.
Most drill bits for drilling wood, metal or masonry incorporate some type of flute in the design.
I'm pretty new to this whole tool thing and I'm thinking of getting an old millers falls bit brace for my light drilling needs, but I want to be able to use a selection of bits that may or may not have been designed to be used with a bit brace.
For light drilling you want the type of hand drill that has a little toothed wheel on the side, that you crank.
To expand a little on what bonobothegreat said above, it's possible to buy a modern brace with a three jaw chuck (Lee Valley has one for example) that will take round shanked bits -- you probably wouldn't want to use it with standard twist drill bits though as they are really not right for it. Bits designed for use in a brace take advantage of the very low RPM and very high torque developed by a brace. I've taught woodworking (in NYC, K-8th grade) for almost 15 years, and I've had my students use old Stanley braces with modern bits without a single problem.

Since right-handed fasteners are loosened by turning to the left, the torque applied by a lefthanded drill bit loosens the fastener. The drills are a great investment too, since they're cheap and last forever if properly cared for.
The only problem is that it's hard to hold the tip of the bit steady in the right place while you start the hole.

Packaging should be the same as what is found in a retail store, unless the item is handmade or was packaged by the manufacturer in non-retail packaging, such as an unprinted box or plastic bag.
Import charges previously quoted are subject to change if you increase you maximum bid amount. Less commonly seen are left-handed drill bits, which have flutes that twist in a left-handed or counter-clockwise direction.
The old drill braces have a special bit holder that matches the old-style bits that have a 4-sided bottom.
If you reside in an EU member state besides UK, import VAT on this purchase is not recoverable. Another important thing about the old bits is that they have a screw on the point that helps pull the cutting blades into the wood.
