Types of Wood Drill Bits
Brad Point Bits
Brad point bits have a sharp center point that keeps the bit from slipping away from the spot that needs to be drilled. It also has two spurs that cut into the wood, giving it a clean finish. These bits are ideal for drilling precise holes in wood.
Auger bits have a screw-like tip that is designed to drill deep and quickly. They are perfect for drilling through hardwoods and are often used to drill holes for lag screws.
Forstner bits have a sharp center point and two cutting edges. They are used to drill clean, accurate, and flat-bottomed holes in wood. They are great for drilling large diameter holes and can be used to drill angled holes.
Spade bits have a sharp point and two cutting edges. They are used to quickly drill large holes in wood and are often used to drill holes for electrical outlets. The large, flat cutting edges help to keep the bit from slipping away from the spot that needs to be drilled.
No matter what type of wood drill bit you need, it’s important to know what a drill bit for wood looks like. Knowing the differences between these various types of drill bits will help you choose the right one for the job.
Features of a Wood Drill Bit
The shank is the non-cutting portion of the drill bit. It is used to attach the bit to the drill. It is usually cylindrical in shape and may contain grooves for a better grip.
The point is the tip of the drill bit and is used to start a hole. It is usually sharp and conical in shape.
Flutes are the cutting edges of the drill bit. They are grooves that run along the shank and twist around the bit. They are used to remove material from the hole.
The cutting edge is the portion of the drill bit that cuts through the material. It is located on the flutes and is usually beveled or angled.
How Wood Drill Bits Work
Wood drill bits are designed to cut through wood and other soft materials. The drill bit consists of a metal shaft with a cutting edge at the tip. The cutting edge is usually made from hardened steel or tungsten carbide. It can be either straight or spiral-shaped depending on the type of wood being drilled.
The drill bit is held in place by the drill chuck, which is then attached to the drill motor. When the drill motor is switched on, the drill bit rotates at high speed. The cutting edge of the drill bit then cuts into the wood, creating a hole.
|Straight||Sharpened to a point|
|Spiral||Multiple edges along the length of the bit|
To ensure a clean cut, the drill bit should be sharp and kept at the correct angle. As the drill bit rotates, the cutting edge will gradually wear down. It is important to replace or sharpen the drill bit regularly to ensure it remains sharp.
When drilling into wood, it is also important to use the correct speed setting. Too slow a speed can cause the drill bit to overheat, while too fast a speed can cause the bit to become damaged. The correct speed setting will depend on the type of wood being drilled and the size of the drill bit.
Drilling Tips for Wood
Choose the Right Drill Bit for the Job: Different types of drill bits are designed for different types of wood. For example, a spade bit is best for drilling large holes in softwoods, while a brad-point bit is better suited for drilling smaller holes in hardwoods.
Mark the Spot: Before drilling, mark the spot with a pencil to ensure your hole is in the right spot.
Drill the Pilot Hole: It’s important to drill a pilot hole first. This hole will help guide the drill bit and ensure the hole you are drilling is the right size and in the right place.
Start Slow: Start the drill slowly and gradually increase the speed as you go. This will help you to get a more precise hole.
Avoid Splintering: To avoid splintering the wood, drill from the good side of the wood and not the bad side.
Secure the Wood: It’s important to securely hold the wood in place when drilling. This will help you to get an accurate hole and avoid any injury.
Use a Backer Board: When drilling deep holes, use a backer board to help prevent the drill bit from walking and the hole from becoming too deep.
Lubricate the Drill Bit: Use cutting oil to lubricate the drill bit. This will help to keep the drill bit from overheating and will help it last longer.
Different Uses for Wood Drill Bits
|Making Holes||Drilling holes in wood for screws or bolts.|

Wood drill bits are used for a variety of tasks, including making holes, countersinking, reaming, boring and tapping. Making holes involves drilling a hole in wood for screws or bolts, while countersinking involves creating a beveled edge around the hole for a flush fit. Reaming is making an existing hole wider or enlarging an existing hole. Boring is creating larger holes like those used for door locks, and tapping is cutting a threaded hole for screws or bolts.
When handling a wood drill bit, it is important to take proper safety precautions. Always wear safety glasses and a dust mask when drilling into wood. Be sure to keep your hands away from the drill bit as it rotates and avoid placing your hands near the drill bit when it is in motion. Make sure to use the correct drill bit for the job at hand, as using the wrong drill bit can cause the wood to split or break, leading to potential injury. Ensure that the drill is firmly secured to the work surface before drilling and that the drill is not held at an angle. Additionally, always unplug the drill when not in use.
