Wood Drill Bits Buyer's Guide
There are many excellent drill bits that will easily cut through wood, yet it comes down to the type of hole that you need to bore.
Understanding the types of wood
Before you decide on which drill bit is suitable for your job at hand, it is important to understand the various existing types of wood. Generally, there are two basic types of wood that you need to know about; hardwood and softwood.
Hard wood vs Soft wood
Hardwoods usually come from trees which basically have leaves only. The typical hard woods include ebony, ash, maple, cherry, oak, mahogany, teak, and rosewood. On the other hand, softwood come from corn-bearing trees. These include pine, larch, spruce, hemlock, yew, redwood, and firs. This is only a general guiding principle although there are some exceptions.
When buying these woods, there are two buying principles that are often used:
- Wood that requires an excellent finish usually called select lumber
- Wood that is for general use and typically it has defects like knots on it
It is worth mentioning that hardwood is typically more expensive than softwood. It is also a bit harder to drill through than soft wood which is when better quality bits come in.
Different types of drill bits for use on wood
The most common drill bits are made from steel, high speed steel (HSS), titanium coated bits, black oxide coated, cobalt, diamond coated and carbide tipped bits. These materials have varying durability. For instance, steel bits are the cheapest and they are good for drilling through soft woods, but they will blunt faster if used on hard woods. HSS bits are ideal for the most purposes and drilling on all types of woods.
- Auger bits - This drill bit features a screw tip thread that starts the hole. It then uses the tip in pulling the bit through the wood so as to make a hole. An auger bit will usually have a really large flute to help in removing the drilled wood. This method was initially used along with hand drills by carpenters and it is still valid today.
A typical set of auger bits will contain up to 10 auger drill bits for a price of about £10 - £15. Buying a set is a great idea as opposed to individual drill bits as you’ll get the best value for money. Plus, a set contains drill bits of varying diameters so you can make holes of many sizes from a single kit.
- Spade drill bits - Spade drills are the best option for drilling large diameter holes. They usually have a hex shank which give a reliable grip in the drill while avoiding slippage or jarring. Spade bits tend to be faster than most other drill bits.
- Hole saw - These are the alternative to spade drill bits as they are also meant for cutting larger holes through wood. They may not have a great deal of use but when the need arises, it is good to have a set that will get the job done. Hole saws are the most expensive of drill bits but they make large, accurate holes than an alternative will do. Hole saws are great for the odd jobs of which you want nothing but accuracy and efficiency.
- Twist bits - Twist bits are all-rounder type of bits commonly used to drill through wood and plastics. They are the best bits for making straightforward holes or pilot holes in wood. You can this individually but again it’s more cost effective to buy a set. Ideally, different sets will have varying sizes of bits and the total number of drill bits.
- Brad point drill bits - These are extremely good for drilling wood due to the pointy end, called brad, which ensures accurate positioning. The brad also helps to avoid any chance of slipping when beginning the initial drilling sequence. They also feature extra wide flutes which help in removing the wood chips and shavings as you drill. These bits give you more confidence when pin point accuracy is required.
- Forstner drill bits - The forstner drill bit is perfect when you need to create a hole with a flat bottom. You can buy these as individual drill bits if you need them, however, they also come in sets. Forstner drill bits are popular in kitchen trades, cabinet making, railings, and other relevant works. They work well in soft woods and also in hardwood with a fair amount of pressure.
- Pilot and countersink drill bits - There are times when you need to countersink a screw into wood. To achieve this, you’ll need to drill a pilot hole then make a screw head shape into the wood. Of course, this gives a pretty clean finish with the help of a pilot and countersink bit. These kind of jobs are rare so these bits are usually for occasional use.

These set is cheap so if you are looking for drill bits to use with hardwood, we recommend spending a little more. They also get hot while drilling so you might be forced to give them some time to cool down in between the drilling to prevent them from breaking.
These drill bits have straight shanks which offer great stability and strength required to drill precise holes. They are tough and super sharp and they seem to retain their edge after extensive use.
Another thing about the set is its low weight. At just 100g, this is an extremely lightweight package, perhaps the lightest in our list too. The storage box is clearly numbered for where to get every bit from and store after every use.
You simply can’t go wrong with these bits.

The major flaw is that they get hot while drilling but that can be managed to prevent warping or breaking, this is probably going to only be a issue with hardwoods that are more difficult to drill..
Overall, they are good drill bits for the price and perfect for home DIY projects or lightly trade use. A great selection at a great price.

Just make sure the drill you are using has enough torque to advance the bit through timber as less powerful drill will struggle. The larger sizes especially do need a powerful drill to be able to keep them turning.
The bits feature full screw tips for easy drilling and pull through. Some practice before doing the job will get you used to them.
They have cutting spurs which deliver clean holes with quite minimal ‘break out’. These bits eject pretty fast due to the Tri-Flute design while the tapered flute ensures there is minimal binding and increased ease of use.
They also have a full length heat treat for increasing durability. The case that carries these bits is uniquely designed to open to the sides with three storage panels on either side.
- Driving these bits through timber requires a fair amount of strength in your arms. Even the larger bits, say 22 and over, need a strong drill with enough torque to keep them turning. You may need to invest in a new drill if you have a cheaper home DIY type drill.
Would we recommend - If you are looking for a quality set of auger drill bits, the Irwin Blue Groove Drill Bit 6 Piece Set is a magnificent option and maybe the last set you will buy.
You will be able to drill holes of different sizes with the smallest being 16mm and the largest 32mm. These bits are sharp and you will love how they eat through wood, creating clean holes and pull out easily, thanks to the full screw tips and the Tri-Flute design.
The downside with these bits is that they require a bit of strength to get the job done, not a bad thing you just need the right drill for the job .
Because a strong drill is required to drive the larger bits through timber which sometimes you might have to invest in a more powerful drill.
All in all, they are great auger bits with a lovely colour and design. They seem a bit on the expensive side yet they are worth paying for as they perform very well and will last many years no problem.
They do a similar job to basic flatbit drills, in terms of performance, these are probably better than the DeWalt Flatbits we have reviewed above but they are a little more expensive.
Which you use is probably down to personal preference. We are very impressed by both types, with both having amazing reviews on Amazon.co.uk so we will have to let you decide, which is more suitable for you. Which ever you choose you won't be disappointed.
Bosch 6 Piece Selfcut - Flat Spade Wood Bit Set
**OUR BEST PICK**
- A set of 6 drill bits ranging from 13mm to 25mm.
- The bits have self-feeding precision ground tips and cutting edges for precise dimensional stability.
- They drill 3 times faster than ordinary spade bits.
Winding up our list is another set from Bosch which drills larger holes than the bits contained in the Bosch X-Pro Wood 7pc Drill Bit Set. The Bosch 2608587793 1/4" 6 Piece Selfcut Flat Spade Wood Bits Set contains 6 pieces of spade bits which include 13, 16, 19, 20, 22 and 25mm along with a ¼ inch hex shank, all of which is contained with a nice wallet.

The bits are incredibly sharp and eat through wood three times faster than standard ordinary bits.
The self-feeding precision ground tips on these bits and cutting edges ensures accurate dimensional stability when eating through timber. It’s worth noting that the total length of the bit is 152mm while the working length is 122mm.
- The case is not numbered for where to keep a particular bit but it’s the bits themselves with the numbering.
Would we recommend - The Bosch 2608587793 1/4" 6 Piece Selfcut Flat Spade Wood Bits Set in Wallet contains good quality drill bits meant for professional and DIY uses.
The foldable case is quite unique in design although it’s not numbered like most other cases but the bits are.
What we like most about these bits are the fast drilling speeds. The packet says these screw end spade bits drill 10 times faster than the pointy end ones and 3x faster than standard spade bits.
If you fancy fast drilling speeds, the Bosch 6 Piece Selfcut Flat Spade Wood Bits Set is one that delivers at a great price.
When compared to the DeWalt set, these are not on pare, but they are good enough for most users, personally if you have the extra budget, we would invest in the Dewalt Flatbits as they are better quality, however not everybody needs drill bits of such as high standard, specially people who are doing a little home DIY which the Bosch Flat-bits are more than adequate.
