Rating of the best countersinks of 2022

Zenker is a family of drills (a type of screw), their main function is to smooth out the bumps that appear in metals, wood, and other materials. With this tool it is possible to make a recess when the holes for screws or confirmations are widened so that their head is inserted flush into the drilled part.

The cost of equipment from a domestic, foreign manufacturer, as a rule, ranges from 100 to 13,000 rubles. In our review, we will provide recommendations: what to look for in order not to make a mistake when choosing a product, which company model is better to buy. Let's get acquainted with popular manufacturers, a description of their drills, and orient by price.

Types of countersinks, how to choose them correctly

Once you understand the meaning of the countersink, the functionality of the corresponding bits will become clear. It is an intermediate process between drilling and screwdriving. The tool is used to produce knots by driving a screw into the workpiece material. After the surface is drilled, countersinking is done, using a suitable bit, you can start screwing. In this case, the head must completely coincide with the surface of the material.

Another job you can do with this tool is to clean up the burrs that remain inside the hole. After drilling, small roughness usually appears, so it is recommended to clean them with countersinks so that you can perfectly fit the fasteners. Products are used to smooth out various types of grooves in all types of metals, ensuring safety in their use.

To your attention the classification, characteristics of various types of products:

• Wood models are the softest of all, they are ideal for working with non-hard materials.
• Metal bits have excellent reliability, used for really hard surfaces, such as iron. They are ideal for carbide machining.
• Drills for aluminum are specially prepared for this material and its characteristics, they cannot be used for other surfaces.
• The main properties of steel models are high hardness and durability. They are quite durable.
• Countersink drills do all sorts of versatile work, varying depending on the type of surface you're going to be working on. Apply them on metal, wood, concrete, porcelain stoneware, stone. They are effective, so it is highly recommended to buy them.
• Carbide tipped bits are commonly used in professional applications because their price and features are not intended for home use.
• Flat models perform standard functions (there is a tool for different materials), the difference is only in the sharpening angle, it is 180 degrees.
• Tubing sets are available in different sizes, depending on their diameter. Another factor to consider is the material, copper tubing is very common.
• The conical shape is used for metal, wood. Provides the ability to create corner spaces for fastening parts with the same geometry.
• screw model.
• The Forstner drill is designed to process wood;
• Feather nibs.

To choose the best products, it is important to understand their design. They consist of three parts that make them an effective tool:

• The first element, probably the most important, is the tip (body). It is in contact with the perforated surface, has cutting edges called teeth.
• Behind the body is the main spike, it determines the length of the working part of the bit, it has two shapes: cylindrical or conical.
• The last part is the head, it is located at the top of the tool, it is the element that connects to the machine. This part, depending on the shape, is sometimes called the “tongue” (shank), it has a different diameter, like the tip.

The countersink angle is critical. Their gradation implies a different application:

• 75° work with rivets;
• 60° deburring;
• 82° countersunk for US sockets;
• 90° for European screws;
• 120° countersinking of sheet metal rivets.

The number of cutting edges is usually odd, which ensures smooth operation. Chips are removed through flutes for removal. Shanks are available in four different versions, let's see what they are:

• trilateral;
• cylindrical;
• Morse taper;
• mounted.

"Tongues" with 3 surfaces prevent slippage of the tool in the drill chuck, making them ideal for use with hand drills. If you want to drill and countersink a hole at the same time, you will need a universal cutter. To get a large number of holes, it is necessary to purchase a bit with a limiter to ensure a constant depth.

If you change tools often, use drills of different diameters in the same project. You may need a hex shank instead of a round one to simplify replacement. People require different attachments, so it's important to carefully consider your needs before purchasing. Some products are more durable than others, if you need a long lasting cutter, please keep the following in mind:

• Titanium is the best material for a countersink. It is usually used as a coating, because the whole product is quite expensive. This is what most premium brands do, especially German ones like Bosch.
• Models with a carbide coating or made from it are popular. This is generally the best option for making durable drills.

If the cutter is cheap, it will usually not be strong.This does not mean that all inexpensive products are bad. But if it costs little, most likely the manufacturer did not spend much time developing its design. When buying a drill, you should consider some selection criteria:

• The tip angle determines whether the head of the screw will be flush with the surface.
• The diameter of the model is undoubtedly important. It is technically possible to make a smaller countersink by drilling shallow, but it is better to have a tool of the right size.

If you are buying a multifunctional device, you need to drill a hole slightly smaller than the screw size. This ensures a tight fit of the fasteners during installation. When choosing a combination cutter, look at its number and match it with the screws you will be using, you also need to consider the shape of the drill. Conical bits help you work faster, provide a strong connection when installing the screw.

How to use a drill

The first thing to do is to adjust the correct working length of the bit. Then drill a hole until the tool reaches the desired point, or depth stop. After that, you need to replace the bit and tighten the screw. The fact that bits need to be changed all the time is the reason why quick change hex shank is so popular.

When cutting hardwoods or metals (such as aluminum), you will need a slightly stiffer cutter, otherwise it will dull very quickly. Design is especially important when drilling steel. It must be ensured that it is able to effectively remove chips, otherwise the equipment may overheat. As far as countersinking technique is concerned, the material does not really matter.Just make sure you have the right protective gear for the task at hand.

Budget novelties are purchased in construction supermarkets. Managers will tell you the points you are interested in: how much the model you like costs, what they are. The product can be viewed in the online store by ordering online.
