Best Boers for perforators: Review

Choose the right drill to create the hole of the desired diameter is a serious task that requires a competent approach. Dozens of manufacturers, different stamps, and drilling materials are presented on the market. In this review, we will designate what Boers exist, how to use them, how to find a good drill for effective work. We will also make a review of the drilling of leading manufacturers with minuses and advantages of models of a particular brand.

Boers are used exclusively for working with a perforator. They are not used for a drill. Depending on the material with which you plan to work, there are a number of different types of drills. Metal, brickwork and wood can be drilled using specially designed structures. They are adapted to the properties of a particular material and will help to achieve the desired result with minimal efforts and time spent. The range of drills also includes special products, for example, to create a hole in a glass surface or tile. For these purposes, manufacturers produce drill with diamond tips from tungsten carbide.

The quality of the drills is determined by the material from which they are made. Accordingly, the type of material that they can drill is determined. Most often, drill are made of materials such as high.Speed steel, with the additions of carbide, titanium, cobalt and other substances that improve the properties of the material.

Boers differ in type of shank. So, straight shanks are used for turnkey cartridges and without it for holes with a diameter of 10-13 mm. SDS shanks are used for appropriate perforators. Hexagonal shanks are used for screwdrivers.

Fixation in the cartridge

The most basic thing you need to understand when buying a drill is the types of shanks. After all, inexperienced masters have situations when, after buying the drill, it turns out that it does not even fit the instrument. Have to return to the store and change to another.

For a better understanding, we will analyze each of the types of SDS system [1]:

SDS-Plus. Most household perforators are equipped with this cartridge. This type is intended for the shanks of the same name, the diameter of which does not exceed 18 mm. The tool is securely fixed thanks to 4 grooves, two of which are responsible for blocking the drill in the cartridge, and the other two set the exact direction of the course with shock pulses.

SDS-Top There is almost no differences from the advantages, but it shows itself better when drilling holes of more than 16 mm. The boat is fixed in a similar way, but it lies deeper into the tool, which increases the area of ​​contact. Such a cartridge is almost always included with a smaller plus version.

SDS-MAX Designed for more serious tasks. However, such a cartridge meets only in the professional series of perforators and is rarely used in everyday life. A drill for such a tool can exceed 18 mm in a shank diameter. The structure of such a shank is similar to SDS, but has additional grooves for energy transmission.

SDS-Quick It is used only in some Bosch perforators. Such a cartridge is considered universal and is able to fix hexagonal bits and drills, in addition to drill. However, it is intended for small diameters and is used only in everyday life.

There is also a fist adapter for a perforator. It allows you to use a perforator in which there is a drilling mode without a blow, with cylindrical cules and even bits for screws. Such a cartridge is useful when there is no drill at hand, but there is an urgent need to drill a hole in a tree, metal, etc.D.

How to choose a drill for a perforator

When choosing a drill, you should FOCUS on such factors as:

  • Manufacturer (quality). Consider at the corresponding paragraph of the article.
  • Tool compatibility. For installation in the nest of which type the nozzle is designed? Advice to beginners. Check with the seller whether the power of the power of your electric tool will be enough: otherwise the work will not be effective.
  • Expediency. Ask the question “Why do I need a tool?””. What material are you going to work with? The holes of which dimensions (depth, diameter) plan to drill? Answers will help get rid of costs that you did not plan.

The sample size of the shank

  • SDS-Plus is a standard, most common type. It is used in most models of light and medium household and semi.Professional electrical appliances. Designed for mounting tools with a rod size up to 10 mm.
  • SDS.MAX is a shank for heavy models performing intensive professional work. Thanks to the constructive features of the SDS-Max, it provides the most reliable fastening of the nozzle, which is important when performing complex tasks. Operate with drill for a perforator with a diameter of 20 mm.
  • Removable fist cartridge is used as an additional. Will be useful if there is no drill or screwdriver at hand, and the need for drilling is. Provides an opportunity to work with a tool with standard cylindrical drills, without resorting to additional devices.

Diameter and length

This parameter describes the size of the hole for drilling with the installed tool. Indicated in the technical characteristics of the goods, as well as the length. The diameter of the drills reaches 80 mm (professional accessories of the SDS-MAX type).

The larger the hole you need, the more the equipment will be demanding on the power of the electrical appliance. If the work obliges to drill regularly, intensively and complex holes, then do not skimp on a high.Quality branded power tool.

Resource (durability)

Professionals have to drill according to many holes every day in various conditions: construction site or repair. The equipment wears out over time, losing performance. Seeing the spread of between budget and high.Quality drill for the perforator, the newcomer will ask the question “why pay more?”, Choose the first. Inexpensive equipment quickly becomes unusable, demanding a replacement.

Durability is affected by the quality of the material, as well as the wear resistance of the attack responsible for the drilling of the material.

Categories and types of drill

The diverse selection of working equipment is explained by the fact that the tool is used when working with materials of different strength. Everyone needs their specific consumables. There are different shanks, dimensions of nozzles, shapes of tips, manufacturers expanding for prices.

We will analyze the differences on the processed material.

By concrete

For a punch for concrete. A solid reinforced person. An element with diamond spraying is suitable: it is characteristic of a high margin of strength. Such details are widespread in a professional environment due to reliability, durability, performance.

By brick, stone

Household drill nozzles for stone and brickwork are often used in internal repair work. Preference is given to nozzles with winning tips, a shank type SDS-Plus.

On wood

Unlike concrete, stone and brick, wood refers to soft materials. Accessories for perforators are not used when working with it, drill will do instead. You need to work with this equipment in drilling mode. The diameter and type of shank are selected in accordance with the required hole size, selected by the characteristics of your power tool.

Drilling wood

In some cases, it is better to use not a standard drill for drilling products from wood materials, but a special boat on wood. Using such a tool allows you to achieve the following advantages.

The cost of perforator drills in concrete is significantly influenced by their length. The price of the longest drills, if we compare it with the price of the shortest tools of the same diameter, can be 3-5 times more.

The most expensive bourars for drilling concrete are special instruments. Such drills, the length of which can be 1000–1500 mm, belong to the category of professional.

Burov test for concrete

Deficit! This word practically came out of our vocabulary. The problem is now relevant: how to choose the best among many goods? For example, we will try to choose brows by concrete with a diameter of 6 mm in a regular construction store. It would seem not the most expensive product, but even when buying it, you can think for a very long time. How should a winch nozzle be? One is good. But two is it not better? How can the drill differ? Which will be able to inhale the larger number of holes. Just do not answer these questions. You need a test!

And here we are before us 7 (more precisely. 8) samples of the drill for concrete from different manufacturers. Where does the uncertainty come from? The reader will ask. All because Bosch drills are different in our test. The general is the diameter of the holes, which should drill brown 6 mm m with the length of the threaded part of 160 mm and the shank for the SDS cartridge.

With each drill, 100 holes were drilled in uninhabited concrete of M350 brand. Drilling depth 60 mm. Distance between holes of at least 40 mm.

When drilling, air cooling was used.

The drilling was carried out by the professional perforator Sparky BPR 240E with the SDS cartridge in drilling mode with a blow. Passport force of hit 2.3 j.

One tester drilled five holes in a row, while the second recorded the time of work.

According to the results obtained, the average drilling time of one hole and the average drilling rate were calculated.

Bosch. A concrete drill with a shankshank, test

Design features: two drills presented in sample 1 differ from each other. Both drills have Bosch labeling, but it is performed in different ways. In the first case, it is applied by stamping, in the second. With an electrician method on the tail of the drill. On the first sample, there is no marking of the series, on the second there is a marking of the SL4 series. The stamping method on the shanks of the drill is applied a sign of the shank of the shank shank and diameter value in millimeters. The second drill indicates the manufacturer-Germany.

The forms of carbide.Sized boraver plates are also distinguished. On one drill, a standard V-shaped carbide plate with an angle of 120º, on the other, it has a centering spike.

The threaded body of the drills also differs. In the drill with the marking of the SL4, the spiral profile has a double groove of the symmetric section, while in the second drill the front wall of the groove has a larger angle than the back.

Test results: after drilling 100 holes of a noticeable decrease in the speed of the Bosch drill, no. At the same time, the average drilling time for the SL4 labeling was 4.7 s, and this was the third result in the group. At the second drill without marking, the average time turned out to be worse. 5.09 C.

Over, the speed was 12.76 and 11.79 mm/s, respectively.

Features of lubricant for a perforator

The composition of the mixture should be such as to comply with the working conditions of the electrical tool under consideration. This is possible, provided that this substance will have the following characteristics:

  • One of the important features of such a mixture is water resistance. The need for it occurs during breaks in the operator’s work. In this case, its temperature decreases significantly, as a result of which moisture is condensed from the air. With high humidity, this can lead to its entry into the tool and reduce the quality of its work. Waterproof lubrication will protect the metal and will not form an emulsion due to whipping parts of the tool.
  • Destability to pollution helps to fight the penetration of dust into the tool. During the operation of the perforator, it is constantly among small particles, which are abandoned from the wall during operation. If the mechanism enters the mechanism, they can greatly increase friction and raise the temperature of the tool. High.Quality lubrication will help protect the mechanism from the effects of foreign particles.
  • This substance should not form drops in the process. This cannot be completely avoided, since the driving parts squeeze out the lubricant outward, but the temperature of their occurrence should be quite high. Such stability will be the higher, the thicker the mixture used.
  • The effect of high temperature should not be destructive for lubrication. When cooling, all properties of this substance should be restored. A lubricant that does not have sufficient resistance to heating will quickly stop performing its functions.
  • A mandatory requirement is the presence of high adhesion. Since the working parts of the tool are constantly in motion, the lubricant should not jump off them when piercing holes in the wall. If the composition satisfies this condition, then in the process of working on all the necessary surfaces a sufficient lubrication layer will be preserved.
  • The nodes of the perforator are usually made of alloy steel or aluminum alloys. The effect of moisture can lead to corrosion and the formation of the raid. High.Quality lubrication can establish a reliable protection of the tool from this.

A good composition must satisfy the listed requirements, but for this, the master must apply the lubricant that is designed to serve punch.
