Driving Bits: Put a Screw In It

All those little jobs around the house require a good assortment of driving bits. You may be savvy about a Phillips vs. a flat-head screwdriver, but what about square drives or even star drives? Did you know that Phillips-head bits come in a variety of sizes (the first size is a 0), or that there are a whole sets of “security” bits available made for special assemblies in industrial settings?

You might not need the special security bits, but a good selection of Phillips, flat, square and star-drive bits will go a long way to expand your assembly (and disassembly) skills. Depending on the model, taking apart a dryer or washing machine can require you to use three types of bits.

For an easy switch from drilling to driving, get a hybrid “quick change” bit. It has a driving bit on one end and a drilling bit at the other end. The tip can easily be loosened, removed, flipped over and set in place to be used.

Drilling Bits

There are drill bits available for every material including wood, metal and masonry.

Wood Drill Bits

Bits for wood come in a wide variety of sizes and a broad assortment of types. A standard wood bit is best for making simple through holes and pilot holes. Most drill-bit sets come in size ranges from 1/16 inch up to 1/2 inch. It's a good idea to pick up a set that includes this range, plus grab a couple of extra 1/16-inch bits. You'll notice these available in multipacks, for a good reason: They tend to break easily. Some sets may include a countersink bit, which creates a large hole at the top of a pilot hole so the head of a screw can sit flush or below the surface of the wood.
