Not only do these bits bore holes faster than standard smooth-finish bits, they create less friction and heat buildup to last longer. The spurred teeth have a long life, but they're less effective at guiding the bit so cuts on angled and overlapping holes tend to be rougher. Also known as multispur bits.

Drill tiny holes by hand in thin and delicate pieces of wood and plastic that a power tool would split. An alternative to a pin vise with separate bits, each finger-grip bit has its own handle, so you can easily switch between different sizes without having to adjust a collet. Bits are made of wear- and heat-resistant high-speed steel.

Make rough holes in wood for jobs such as running wire and pipe through framing studs and sheets. These bits have two sharp edges for faster cuts than fluted bits and won't cause the surface of the material to splinter. A centering point keeps them stable while drilling soft and hard woods such as pine, plywood, and oak. Also known as spade bits.

Multiple teeth cut away large amounts of material to bore clean, flat-bottom holes in wood. The center guide point keeps the bit stable and centered for drilling straight, angled, and overlapping holes, like those used create joints. Also known as Forstner bits.

Drill and counterbore holes of different depths without changing tools. These counterbores move along the drill bit (sold separately) and lock into place with set screws to match the length of the screw you're installing.

These countersinks attach at various points along the drill bit, so one tool will drill countersunk holes for screws of different lengths. They're designed to cut a smooth and even finish in wood and plastic on the first pass.
