Boer: appointment
Drills and drills are consumables, but their importance in design is high. The element is an 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 there is also a diamond soldering. This solution will increase the service life and wear resistance. It has a tail section, where special grooves are located, a spiral rod and a cutting section. Like the drill, it is installed in the chuck of the hammer drill. 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 cannot be used for working with metals or wood, as it is not designed for this. For such purposes, it is worth buying the appropriate tools.
Boers 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 this size. The maximum diameter is 5 cm. In the professional field, builders use material in lengths: 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. Only in this way will a person ensure the greatest efficiency and durability of the nozzle.
Drill is not a drill
According to outward signs, these elements have a minimum of differences, which is why an unknowing person can get confused and buy the wrong option. In addition, they also have the same purpose - to create holes. The only difference is that the drill is designed for working with plastic, wood and metal, but the drill is used only for concrete or brick surfaces. Often, because of this ignorance, they buy a standard drill, and when they come home, they immediately break it.
A drill is many times stronger than a conventional element, and also has a large size and diameter. The maximum value of the drill section is 14 mm, for an impact-cutting product this figure reaches 55 mm. In addition, the design of the shank is different. So the drill has special grooves, while the drill does not.
The product is used in every hammer drill, even a hammerless one, 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, with which it is securely held in the center of the hole. Also, the impact-cutting tool is distinguished by its durability, but the price for this product is several times higher.
Drill types
Like most similar tools, the drill is not available in just one form, there are hundreds of variations in the store. Some are for concrete and others for demolition. The scope of application is determined depending on the design.
Auger
It is a self-sharpening element that is only used when drilling deep holes. Able to work for a long period and not break, while the quality of the grooves made is at a high level, no defects and cracks are formed. The service life of the auger drill is tens of months.
This element is often used to create cylindrical holes. To create a groove with a larger diameter, it is necessary to use a lance that functions like an electric hammer.
For dismantling and installation
Such models are designed for dismantling and work with many materials. To carry out the installation of electrical outlets, you must 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 to organize 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 decrease, and the chips will be separated quickly.
An earthen 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 to look for
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 the tool, just look at the shape of the edge, which is fixed in the chuck.
The product has a cross section with a complex configuration, so it can be with a small groove, bulge, SDS, etc. Unlike a drill, the drill has a standard round shape.
A complex 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 variety, 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 household area.
- Max - designed only for professional use, as they have a higher power.
General recommendations
In order for the part to last 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, a protective layer that is applied to the outer surface will prevent corrosion.
If a person plans to use a drill when carrying out home repairs, then buying expensive equipment is impractical, since its potential will never be revealed.
Products of the domestic segment will become available elements with high reliability. If you treat such drills with trepidation (lubricate, do not overload, clean), then their service life will double.
Cheap firms are good, but it is better to refuse such products, since the quality of the material used will be at a low level. Only if a person needs borax for a single use, then it is worth buying them. Otherwise, they are useless. It is better to purchase a product from a well-known brand that values its reputation.
When performing a large amount of work and frequent use of 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 from frequent use. In addition, the accuracy of these drills remains high.
If the buyer does not know which option to choose, then it is best to choose a well-known manufacturer, about which he knows a lot of positive things. It is not recommended to trust one-day firms or unknown Chinese companies.
Applying the described recommendations, the user will avoid common mistakes when buying and will make 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 is given much more of a role than an electrical appliance.
