No construction work is carried out without a hammer drill. The quality of the grooves created is influenced by an element that is unremarkable at first glance - the drill. Therefore, attention is paid to his choice.
The editors of the YaNashla website have prepared for you a rating of the best hammer drills for 2021.
Bur: purpose
Drills and drills are consumables, but their importance in the design is high. The element is a impact-cutting element. Novice builders sometimes confuse this product with a drill, but there is a big difference between the two.
The drill is made from alloy steel, but also has diamond brazing. This solution will increase service life and wear resistance. It has a tail part where special grooves are located, a spiral rod and a cutting part. Just like a drill, it is installed in a hammer drill chuck. We must not forget that the drill is a consumable item and is often used to create holes in a concrete or stone wall. The product should not be used on metals or wood as it is not intended for this purpose. For such purposes, it is worth purchasing the appropriate tools.
Drills are sold in different lengths and diameters. If a person is looking for an option for use at home, then a good solution is 6-10 mm. In this case, it is necessary to select a dowel that is suitable for these sizes. The maximum diameter is 5 cm. In the professional sphere, builders use material with a length of from 10 to 100 cm. It is important to understand that when making technical holes, compliance with the diameter and length is a mandatory requirement. This is the only way a person will ensure the greatest efficiency and durability of the nozzle.
A drill is not a drill
In terms of external signs, these elements have a minimum of differences, which is why an ignorant person may get confused and buy the wrong option. In addition, their purpose is also the same - creating holes. The only difference is that the drill is designed to work with plastic, wood and metal, but the drill is used only for concrete or brick surfaces. Often, because of this ignorance, people buy a standard drill, and when they get home they immediately break it.
The drill is many times stronger than a conventional element, and also has a larger size and diameter. The maximum cross-sectional value of the drill is 14 mm; for impact-cutting products this figure reaches 55 mm. In addition, the design of the shank differs. So the drill has special grooves, while the drill does not.
The product is used in every hammer drill, even hammerless ones, but it is not intended for use in a drill. Some drill models are manufactured with multiple cutting inserts and may also have a special geometry that holds it securely in the center of the hole. Also, impact cutting tools are durable, but the price of this product is several times higher.
Features of drills
In order to choose the right drill for concrete structures, without making mistakes, you will need to know the features that distinguish them from products for metal and other materials.
The shape of the working area will be quite blunt; this area is made of a Pobedit plate. This type is suitable for concrete as woodworking products will include sharp tips. Due to this, at the beginning of the work, the wood is stuck inside, and only then a hole is made. The working area of a metal product is similar to a cone with no sharp points.
The color of concrete products is often metallic white. Products for wood will be strictly metal, and for metal, black colors are used.
Types of drills
Like most similar tools, the drill is not available in only one form; there are hundreds of variations in the store. Some are designed for concrete, while others are for dismantling. Depending on the design, the scope of application is determined.
Screw
This is a self-sharpening element that is used only when drilling deep holes. It is able to work for a long period and not break, while the quality of the grooves made is at a high level, no defects or cracks are formed. The durability of an auger drill is tens of months.
Often this element is used to create cylindrical holes. To create a groove of a larger diameter, it is necessary to use a pick, which functions on the principle of an electric hammer.
For dismantling and installation
Such models are designed for dismantling and work with many materials. To install electrical sockets, you need to use a part in the form of a crown. Using such a drill, a person will receive a high-quality hole of the correct shape, which will make it easy to place the necessary elements. This type is used for organizing water supply, as it is able to create the required diameter for laying pipes
For wood and earth
For wood, you can use not only a special drill, but also a drill, the latter will be many times superior to the element in terms of technical indicators and processing quality. Using such a tool, the working force will be reduced, and the chips will be separated quickly.
An earth drill is used to create round and neat holes. Thanks to the special structure of this device, a person will be able to create a hole of the required depth with minimal effort.
What is different about a concrete drill?
It has a special brazing made of a reliable alloy with a hardness level comparable to diamond. We are talking about victorious coating.
Equipment for drilling element for concrete:
- Can be used in conjunction with a drill. The design of the drill is distinguished by the presence of a tail with a cylindrical or multifaceted shape;
- For a hammer drill. It is made in a shape similar to a shank or cylinder. For marking, the inscription SDS PLUS or SDS MAX is used.
What to pay attention to
There are hundreds of attachments in the store, and it can be difficult to determine exactly which one is suitable for a particular situation. Sometimes it takes several minutes to find a drill, especially if there is no consultant on the sales floor. To quickly identify a tool, just look at the shape of the edge that is fixed in the chuck.
The product has a cross-section with a complex configuration, so it can be with a small groove, convexity, SDS, etc. Unlike a drill, a drill has a standard round shape.
A complex cross-section is necessary for this tool, as it guarantees a tighter connection with the chuck of the electric tool. All attachments are classified into different categories to make it easier for a person to find a specific model. However, despite all this diversity, two types are considered popular:
- Plus for 4 slots, this option is used for electrical appliances with low power, which are most often used in the domestic sphere.
- Max - intended only for professional use, as they have higher power.
General recommendations
In order for the part to serve the maximum period and not break at the wrong time, it is recommended to frequently lubricate moving parts. To accomplish this, gel substances (for example, products from ARSENAL) or in the form of a spray (for example, WD40) are suitable. In addition, the protective layer that is applied to the outer surface will prevent the corrosion process.
If a person plans to use a drill when carrying out home repairs, then it is not advisable to buy expensive equipment, since its potential will never be revealed.
Products from the domestic segment will become affordable elements with high reliability. If you treat such drills with care (lubricate, do not overload, clean), then their service life will double.
Cheap companies are good, but it is better to avoid such products, since the quality of the material used will be at a low level. Only if a person needs drills for one-time use, then it is worth buying them. In other cases, they are useless. It is better to purchase a product from a well-known brand that values its reputation.
When performing a large volume of work and frequently using a hammer drill, it is better for the user to buy professional copies, as they are more resistant to mechanical wear and will not break due to frequent use. In addition, the accuracy of such drills remains at a high level.
If the buyer does not know which option to choose, then it is best to choose a well-known manufacturer about whom he knows a lot of positive things. It is not recommended to trust fly-by-night companies or unknown Chinese companies.
By applying the described recommendations, the user will avoid common mistakes when purchasing and will carry out high-quality installation at home. It is important to understand that productivity is affected not only by the cost of the tool, but also by the equipment used. The latter plays a much more important role than the electrical appliance.
