Wood drill bits are required for almost every woodworking job, whether you're working on a carpentry project or making a birdhouse or hammock.
The type of drill bit you'll need to make a precise hole in the wood depends on your project and the wood you choose. High-Speed Steel (HSS) and spade drill bits are ideal for every woodworking job. In HSS you can choose black oxide and titanium coating. The black oxide coating extends the life of your drill bits, while the titanium coating reduces friction and keeps your wood drill bits sharp for longer.
A spade bit is also the perfect drill bit for your woodworking projects. You can choose a spade drill bit for drilling holes of multiple diameters.
Let’s know what is the difference between a spade bit and a boring bit.
Spade bits are also known as paddle bits or flat boring bits or wood bits. They are wood boring drill bits used to drill through all types of wood, plastics, and thin metals.
These bits are also used to drill multiple holes in a short time, although these tend to be rough holes. Spade or paddle drill bit has two main cutting edges, two cutting spurs, and a central point at the top for more precise drilling. They are less expensive than twist drill bits, auger drill bits, and hole saws.

A boring bit is a drill bit used to make cylindrical holes in materials such as wood, drywall, and thin metals. The boring bits rotate around the surface with the help of a drill to make a hole in the surface of the material.
Flat Bottom Boring Bit is used to drill large diameter holes through wood. They are used to make locks, doorknobs, and wiring holes. Flat bottom boring bits are designed to work only on wood or plastic materials, not steel.

The 10 most common types of wood-boring drill bits are:
The most common type of drill bit used for general purpose drilling in wood, plastic, and thin metal.
This wood drill bit is designed to cut and drill clean holes in soft and hardwoods without splintering.
Another type of wood-boring drill bit with a sharp screw tip at the top to guide the drill bit's movement into the wood. An auger bit can drill more precisely and clean holes than spade bits and twist bits. Sizes of these drill bits are available up to 18 inches.
A self-feed bit is used to make clean holes in wood. This drill bit is somehow similar to an auger bit (though more compact) and has a screw at the top which helps the bit to remain stable during drilling.
This is a special twist bit designed to drill small holes for installing cables, internet, power, and security wires. The installer drill bit can be up to 18 inches long to drill through wood, plaster, and some masonry.
A spade bit or paddle bit is used to drill large diameter holes (up to 1-1/2 inches) in wood, plastic, and drywall. They can also drill multiple rough holes in a short time.
A perfect wood boring drill bit. A hole saw bit can drill large holes required for the door, hardware, and accessories installation. A bi-metal hole saw can cut through wood and metal.
The countersink drill bit or screw pilot bit is a special drill bit for wood. This drill bit can drill pilot, countersink, and counterbore holes in a single-use.
The step drill bit is wood as well as a metal drill bit. This bit is designed to drill thin metal (up to 1/4 inch). The stepped design in this drill bit allows you to drill holes of multiple diameters.
