8 Best Drill Bits for Wood - Reviews
For Rough Surface Applications
1. Spade Bits
These bits look just as the name suggests. Every shaft terminates into a spade-shaped blade. The spade at the ends is flat and features a sharp point at the very center. This point acts as the guide and helps to center the hole as well as lead the way. Do not be deceived though, the cutting edges are still the part that does the heavy lifting.
It is worth noting that spade bits are probably the cheapest there is on the market and bore holes at great speeds. Their simple design makes them easily modifiable which may come in handy when you need a smaller size bit.
>>>Recommend: Irwin Tools 341008 Spade Bit Set

2. Hole Saws
This type of drill bits features two parts the blade and the mandrel. The mandrel in layman terms is the shaft onto which the blade has been attached. It is the mandrel that fits into the drill allowing the unit to be rotated fast and drill holes. The blade, unlike other blades you might be used to is a hollow cylinder that comes with teeth at the top edges.
It is worth pointing out that hole saws are designed to handle work that is in between the prowess of spade bits and saber saws. In addition to being able to drill through wood and plastic, hole saws can also handle other metals including steel, aluminum, and iron. These drill bits for holes in wood are most important when installing cables, conduits, tubing and piping.

3. Auger Bits
As we start out, note that these come in different makes and designs which make them best suited for certain specific uses. These include wood-boring augers, triple fluted wood bits, carbide-tipped auger bits, ice auger, concrete auger and earth auger. From the names, it is quite clear the application each type has been designed for. Of all these types, however, we shall focus on the wood auger bits.
Needless to say, these are perfect and ideal when drilling large and deep holes in thick wooden boards or dry timber. The screw thread added to the tip of the drill bits draw the bit into the material thus eliminating the need to push down on the unit. The single spur cutting edges on the other hand scribe the circumference thus providing a smoother finish.
The large flutes carved onto the design of the shaft help to get rid of the wood chips as the unit makes its way into the cross-section. Many feature a hexagonal shank which helps to provide a secure and firmer connection between the bit and chuck.
>>>Recommend: Bosch Daredevil Auger Bits
The best and recommended auger bit is the Bosch Daredevil NKLT16. This is a 1-inch unit even though you have a whopping 15 sizes to choose from.

The hollow center flutes help to clear the chips away fast which makes the entire boring business a breeze.
5. Installer Twist Bits
To effectively explain this, it is imperative that we start from the basic of what a general twist bit is. These are probably the most common drill bit type designed for handy home use. They are designed for general purpose drilling through plastic wood and some light metal.
Now, that said, installer twist drill bits are of course a type of twist drill bit, only more specialized and made for wiring including security and entertainment systems. After drilling through a wooden surface or any other surface you might be working on, you can insert a wire into a small hole running through the bit and use the drill to draw the wiring through the hole you just made.

Their design allows users not to go through the wood. That said, there are two kinds of Forstner drill bits; those featuring a saw tooth rim and those with a continuous rim.

They are constructed to be durable, able to withstand constant wear and tear.
7. Brad Point Bits
These drill bit types feature a brad point tip hence the name. The tip is also referred to as W-point tip. This allows for outside cutting edges to cut out a diameter before the center of the bit breaks through the surface. This helps to prevent grabbing which results in a cleaner hole. The unit is as such perfect for drilling through plastic and wood.
Many of these drill types come with rubber rings which help you control the depth to which you will drill through your material.

8. Self-Feed Bit
These like the auger bits are designed with a screw at the tip that helps to not only draw the wood to the bit as it works through the material but also helps in positioning the bit in the first place. However, many of these do not feature flutes like the twist bits do and as such, you might have to pull the unit back every once in a while to clear the dust and chips in the hole made. There are some on the market, however, courtesy of tech advancements that have these flutes.
