Bits are accessories often used with tools such as drills, and they come in two varieties: driver bits and drill bits. Driver bits are designed for driving screws, while drill bits enable you to make holes in materials such as wood and metal. This article will focus on bits for drilling holes in wood.
Drill bits make holes in wood, metal, plastic, and other materials. They come in different types and sizes, but all contain a sharp edge to cut away material as the bit spins around. In the case of wood, these types of bits can be used to make pilot holes, enlarge existing holes, countersinking screws, and more.
The parts of a drill bit vary depending by type, but most have a few common elements: 1. Shank: The shank is the part of the bit that fits into a drill’s chuck, a clamp that holds the bit in place as it rotates. Drill bit shanks come in two common shapes: hexagonal and round. 2. Tip:The tip or point is the sharp end of the bit and is usually angled...
The twist drill bit or twist bit is the most common bit used for making holes in wood, and it’s what probably comes to mind when you think of a drill bit. Twist bits have a cylindrical shape, a sharp point, two cutting edges, and two spiraling flutes that remove material from the hole as it turns. They are usually made of high-speed steel and avail...
A spade bit, sometimes called a paddle or flat bit, is designed for making large holes in wood. Spade bits have a flat, paddle-like shape with two sharp cutting edges, allowing them to cut away material quickly. You can purchase paddle bits individually or as a set. Typical sets often come with bits ranging from 1/4-inch to 1-inch. Spade bits are i...
Brad point bits are designed for drilling precise holes in wood. If you look closely, you’ll notice they look like a combination of a spade and twist bit featuring a pointed tip, two cutting edges, and usually two flutes. The stand-out features of a brad point bit are its tip and cutters. The tip eliminates using an awl to create a starting point a...
A pilot point bit is a variation of a twist bit, with a tip that makes its own pilot hole and cutting edges that efficiently bore a clean hole. The pilot point tip is less likely to wander than a regular twist bit, but sometimes it’s tricky to get the tip perfectly positioned on your mark. To avoid a misaligned hole, I recommend using an awl before...
An auger bit is ideal for drilling deep holes with smooth edges in wood. Its screw-like tip keeps it on course and pulls the bit into the material. At the end of an auger bit, two sharp points known as spurs score a circle identical in size to the hole you’re drilling. Two cutting edges cut away material within that circle, while spiral flutes help...
A Forstner bit performs a similar function as a spade bit, but it does so more precisely, producing a smooth-sided hole with a flat bottom. Forstner bits are ideal for making clean-cut holes partially or entirely through wood, but what sets them apart from typical drill bits is their outer cutting edge guides them instead of the center tip.

A countersink bit allows you to make a recess in wood so that the screw head sits flush with the surface. Not only does this prevent tearout and reduce splitting, but it also ensures the screw makes better contact with the material. On top of that, countersinking screws give your projects a much cleaner and more professional appearance. Related: Ho...
In the manufacturing industry, a tool holder is a device used to securely hold a cutting tool or drill bit in place during machining operations. Tool holders come in a variety of shapes and sizes, and are designed to fit specific types of cutting tools. They are typically made from high-strength materials such as steel or carbide and are ...
- Twist Drill Bits. These are general purpose drills, and we use them to drill plastic, steel, and wood. The angle of a twist drill is such that they cut steel rather well, but you can drill holes in wood as well.
- Dowel Drill Bits. Also known as lip & spur wood bits, these bits have pointed center, and cutting edges which take angles in the opposite direction. The function of the pointed center is to keep the drill centered, so it does not wander off during drilling.
- Flat (Spur) Drill Bits. These bits have a “spur” (also called “brad”) and a lip. You can easily identify the drill bit as it has a unique shape. We use spade bits to create larger holes in wood that exceed the normal diameter of the drill bit that you can fit into the chuck of a power drill.
- Brad Point Drill Bit. You may also come across wood drill bits that resemble metal drill bits. In such a case, the difference is more subtle – the material used will be softer, and the bit may be differently colored or marked.
Jun 3, 2023 · Step 1: Mark Your Cutting Line. The first thing you need to do before you even pick up your drill to cut wood is to mark your line across the surface of the wood. This will show you exactly where you want to cut and allow you to get the most accurate and precise cut. Using a straight edge or a chalk line will help you get this part of the job done.
