What is countersink?
The word countersink does not refer exclusively to actions in wood: According to the dictionary, it refers to the widening of holes for the introduction of nails or screws, or even the action of making the nails and screws totally inside a certain object , without the head outside.
When we talk about countersinking, therefore, we are talking about making a hole that is wider at the end, so that the screws can have their head also inserted. This is especially important for parts that need a good finish, craftsmanship or high-end products.
Countersinking is mainly done on wood, but it can also happen on plastics, metals, concrete and other surfaces. To do this, simply have the appropriate tools to make the necessary holes safely.
Did you know that countersinking can be done even on large surfaces or walls? There are huge machines capable of carrying out this process on an industrial scale. John Wilkinson was the inventor of the countersink in 1775.
In what situations should a wood be countersunk?
But, after all, when should you bore a wood? Why have tools that help you do it accurately and safely?
- Finishing in crafts : Hiding the screws of your crafts is fundamental to the aesthetic beauty of the pieces. So, if you use large woods and need to pass through a joint, there is nothing like reaming: Your work will have much more visual quality!
- Working with furniture : The look is fundamental in the manufacture of furniture. Bolts on display disrupt the assembly and make the final work unsatisfactory. Whether in industries or artisanal production, countersinking is always indispensable in this niche.
- Wooden structures : In huts, floors or structures like domestic bars made with wood, the issue is not only aesthetic, since screws out can even hurt people. Countersinking is also necessary for quality and safety.
It is worth mentioning that countersinking can also be done in parts and similar situations with other materials, although this is not so common.
Countersink or reamer drill?
There are two basic ways to make a countersink, and they are similar to each other: Through a reamer or a reamer drill. Both ask for a tool such as a drill to be used.
Countersinks are small extended parts that must be attached to common drills. Fixing usually takes place with an Allen key. They have limits on diameter compatibility, but usually already serve a satisfactory range of accessories.
Countersunk drills, in turn, are already made for countersinking, with the tip enlarged. They have different sizes and diameters and need only be placed in the drill, exactly as it would be done with ordinary drills.
Your preference should be the main factor in choosing which type to use. Countersink drills are more practical, as the exchange is easier, and lasts longer, since the use varies widely. The price of a kit, in turn, is higher than that of a reamer.
We compare the two types in the table below:

How to use a reamer correctly?
If you choose to buy countersink drills, the use is quite similar to that of ordinary drills in a drill. Attach them with the mandrel (either by key or by quick change) and then make use of it. There is not much secrecy in the process.
The reamer, in turn, needs to be attached to the regular drill. This is usually done with an allen key, which may or may not come with the accessory. Remember that it should be on the tip of the drill bit, not half, since the hole will only be wider at the beginning.
Experts recommend that the countersink be done before the hole, that is, it is necessary to measure the screw that will be used, find the correct drill and work on this extended part. It is also necessary to use high turn for the result to be appropriate.
Quality drill and screwdriver will also be able to help you a lot in the countersinking and screwing work.
How much does it cost and where to buy a reamer?

Purchasing criteria: Factors for choosing a reamer
Now that you know you should buy a reamer or reamer drill, it’s time to choose the ideal model. We have selected some important criteria to help you:
- Cost benefit
Below, we’ll talk in more detail about each one!
What are the screw sizes you usually use? Are the heads usually wide or thin? Do you know the exact dimensions?
Reamers have minimum and maximum diameter sizes. They indicate which drills can be installed, representing the dimensions of the holes to be drilled. Thus, you always need to observe the values indicated before finalizing the purchase.
Countersink drills, in turn, have varying diameters, as well as normal ones. They come in kits with a high number of parts. It is important to note whether the required size is covered by the chosen set.
A countersink is usually quite small. Countersink drills are larger, but still easy to lose, especially if stored in any way. Any purchase you make should help you to safely store such accessories.
A quality case or case increases the durability of the countersinks.
Always prefer countersinks or drills that come with cases, briefcases or pockets that facilitate transport and storage. This not only improves practicality on a daily basis by reducing the search time, but also increases the durability of each piece.
If you buy a model that does not facilitate storage, immediately look for an easily accessible place to store the accessories, preferably without large quantities of other tools together.
The attachment of a countersink drill is very simple, after all, the operation is the same as a common one. Just press the selected part into the drill chuck and use it, without the need for adjustment
In the case of the countersink, however, the situation is more complex: It is almost always necessary to use an allen wrench, a tool that is not as common or easy to find. Before connecting the drill, check that the tightening has been done well and that the part is in the right place.
Good countersinks also allow for a depth adjustment of the piece in the drill, important for those who want to leave the screw perfectly hidden inside the wood.
Whenever we buy items that come in kits, we need to pay attention to cost effectiveness. This is the case with countersinks, but mainly with countersink drills.
Remember to divide the total price of the drill kit by the number of units offered. This way, you will know exactly how much you are paying for each one and will be able to compare each option more efficiently.
