Best Drill Bits for Wood Reviews 2017
This article will help you find the best drill bits for drilling wood. If you are someone who likes working with wood, or perhaps have a project to do, that will include making holes in different types of wood, then hopefully you will find this article very helpful.
There are a number of excellent drill bits that will easily bore through wood, but it really comes down to what type of hole you need to make. There are more than you may initially think, but we will cover that off later in this article.
Knowing The Wood Type You Are Drilling
Before picking a drill bit, it is just very useful to understand the different types of wood that are available. In essence there are really only two types of wood that you need to know about and these are:
- Hard wood
- Soft wood
Hard Woods vs Soft Woods
These will come from trees which essentially only contain leaves. Soft woods come from trees that bear cones. Now there are some exceptions but this is a general guiding principle. When people come to picking out woods there are two buying principles that should always be used:
- Wood that needs a good finish often called select lumber
- Woods that are for general purpose use and will typically have defects such as knots in it.
Typical hard woods include ash, beech, cherry, ebony, maple, mahogany, oak, rosewood, and teak.
Typical soft woods include larch, pine, redwood, yew, hemlock, firs and spruce
The main reason this is important to know is that hard wood is typically more expensive than soft wood. Hard wood is also much harder to drill through than soft wood. You can use the same drills, but it will take more effort when faced with the harder type woods.
Various Types of Drill Bits For Use on Wood
Most drill bits are made from steel, high speed steel (HSS), cobalt, black oxide coated bits, titanium coated, diamond coated or carbide tipped. In the main this will determine how long drill bits actually last. For example a steel bit will be the cheapest and is fine for drilling through softer woods, but will blunt quickly if used to drill through any type of hard wood. For the most purposes HSS bits are ideal for drilling through all types of wood.
The Twist Bit
This is the all rounder type of bit commonly used to drill through wood and plastics. These are used for drilling the small straightforward holes or for making pilot holes in wood.
These can be bought individually, but is is more cost effective to buy them in a small set, like the one pictured here. This set is a huge best seller, and is from the high end Dewalt brand.
This is a fairly typical set, and in this case they have been coated in black oxide to prolong their lifespan. Depending on what set you give they will all have a different amount of bits. This one for example has 13 drill bits that cover a range of 1/16″ to 1/4″ so that is a good all round set to have in your toolbox.
When finished with each bit, then simply pop it back into its place and close the lid. That of course stops you losing the bits which is easier to do than you may think.
Brad Point Drill Bit
These are really good for drilling through wood as they have a point, known as a brad, for really accurate positioning. They also have extra wide flutes which help remove the wood chips and shavings.
You can notice from the picture the brad point allows you to push it down into the wood for real accuracy. These are very popular with anyone who works a lot with wood.
They certainly avoid any potential of slipping when starting up the initial drilling sequence. You do feel a lot more confident when using these especially if pin point accuracy is really important.
Initially though when the hole is being created you may find that these will tend to jar a little more than a twist drill bit. Depending on the size of hole being drilled, some people will use a twist drill to make a small pilot. Personally I have never found the need to do that.
An auger drill bit has a screw tip thread to start the hole, and it then uses this to pull the bit through the wood to make the hole. You will find that all of these types of bits, will have really large flutes to help remove the drilled wood.
These were initially used with hand drills by carpenters, and indeed many still use that method today. Those old type of drills were called a brace and are still popular enough.
Personally I use an electric drill set a fairly low speed and that works very well. Again buying a set is probably the best idea simply to get the best value for your money.
These used to be very expensive to purchase, but typically you can get a set of 9-10 auger drill bits for around $15-20 and they will be very good quality. The Pit bull branded bits are shown above.
If you need to drill deep clean holes in wood, then these are typically what you should use. The case I have shown contains 3/8″, 15/32″, 9/16″, 5/8″, 11/16″ and 25/32″ and that will give you the bits to do most jobs in and around the home.
Those are in fact the main type of drill bits, that you will need to drill through wood. If you have a set of each, you are pretty much in a really good position to be able to drill through all the different types of woods. It is just worth mentioning that there is no need ever to use the hammer function, when drilling wood. The most popular choice for many people is the Dewalt drill bits shown above.
I have seen people do this and all they get is the smell of burning wood and a really blunt drill bit. There are however other types of bit for drilling through wood that you should know about.
Spade Drill Bits
If you are someone who needs to drill large diameter holes, then you will need a set of spade drills. It is either that or buy a hole saw. I am not a huge fan of Bosch when it comes to drill bits, but a friend of mine recommended these to me, and he was right.
Previous to that I had used both my favorite brand DEWALT and also Black & Decker spade bits, but these are in my opinion, just so much better.
They are at a sensible price point at under $20 for 10 useful sizes ranging from 3/8″ to 1 1/4″. With these you do get a nice cleanly drilled hole and that is all that I am ever looking for.
The hex shank makes for reliable gripping in the drill and also avoids jarring or slippage. These bits are also fast which yet again is what I want.
I mentioned a hole saw earlier so thought it would do no harm to include it here. These are of course designed for cutting larger holes through wood with diameters from around 1″ up to 2 1/2″.
These will not get a great deal of use, but when you need to, it is nice to have set that will do the job. There are plenty to choose from but for these I once again revert to DEWALT.
Yes they are more expensive than any of the others, but they work each time, every time. When you are doing jobs that need this type of hole drilled, you want two things in my opinion.
The first is to be able to actually get the job done, and the second is accuracy and time. You can’t afford to make mistakes when doing work like this, which is why I own these.
If you are only doing the odd job and you need to use a hole saw, then a cheaper set will do the job. With something like these, you will be able to get a few holes done, but they would not be that good for extended use.
Forstner Drill Bits
If you are drilling into a piece of wood, and you want a flat bottomed hole, then the perfect drill bit for you is called a Forstner bit. I would recommend buying these individually if you need them, however they also come in sets like the one I have shown.
These are very popular in the cabinet making and the kitchen trades. For the really high end bits you could easily pay up to $100 for a single bit.
Many of the trades do, but the set I have highlighted here is ideal for people who need this type of hole for their hobby, or are keen DIY people.
I have used these to make a few wooden toys and they work really well and are still going strong. They are also great for doing railings or for drilling out holes for spindles etc. These work really well in soft woods, but in hard woods I tend to let the bit do the work, and don’t apply too much pressure.
To get the best use out of these you will need a a 5 Speed Drill Press
Pilot & Countersink Bits
There may be times when you need to countersink a screw into wood. To do that you basically need a drill that will create a pilot hole and also create a screw head shape into the wood. This of course gives a really neat finish.
The set I have shown is once again ideal for occasional use and for this price you get decent quality. Again a heavier user should consider paying a bit more for a higher quality set.
For most people though, these will do the job. People did complain about the packaging on this but I guess that is one way of keeping the price down.
So that folks sums up the different types of drill for drilling through wood, both soft and hard. As you can see there are certainly plenty of options available.
