A low-speed drill belongs to the group of professional construction tools. This device received this name due to the high torque required when drilling large-diameter holes. In addition to high torque, the drill is equipped with a high-power electric motor, which makes the tool capable of withstanding significant loads. The tool in question is also called a drill-mixer, as it is often used for mixing solutions of different mixtures.
What types of drills are there?
The best manufacturers have filled the market with popular drill models. They differ in functionality, characteristics, design features, and scope of application. Despite the diversity presented, all manufactured products are divided into the following main types:
- professional;
- semi-professional;
- household
Once you have decided on the area of use, you need to select a model based on its purpose and operating principle. The following types of goods are presented on the market:
| Name | Description |
| Corner | An indispensable tool for working in confined spaces. The body tapers towards the working end. L-shaped gearbox. The cartridge is located at a right angle to the unit body. Popular models are corded and cordless with a screwdriver function. Experts recommend not to lose sight of the angular size when choosing. A review of reviews shows that the smaller it is, the more functional the device. Used when drilling in narrow ceiling or wall spaces. |
| Drums | They belong to the category of universal ones. Able to handle hard materials. An indispensable tool for construction and installation work. Combines the functions of a conventional drill and a hammer drill. Functions in two modes: drilling and drilling with impact. A rotating shaft connects the chuck to the gearbox. The ends of the shaft are equipped with gears. When drilling, they rotate simultaneously. When switching to hammer drilling mode, the gears move in different directions. In this case, the gear gear becomes stationary, and the cartridge gear rotates. Used for drilling timber, metal and synthetic plastic surfaces. |
| Unstressed | The main structural element is the electric motor. For work, quick-release and key chucks are used. You will need a wrench to tighten the key cartridges. Quick-clamping analogues are replaced in a matter of seconds and without the use of significant physical effort. Keyless chucks come in double-clutch and single-clutch versions. The unit is used for precise and clean drilling of metal, plastic, and wood. Working with concrete, stone and brick should be avoided. |
| Cordless drill/driver | Belongs to the category of battery hybrids. Based on the location where the handle is attached, there are L-shaped and T-shaped. The handle is attached in the middle of the body, closer to the engine, which reduces the load on the hand and increases the pressure on the drill or chuck. Equipped with a gearbox with a low gear ratio. Number of speeds – 3. At the first speed, the tool is used as a screwdriver, at the third – as a powerful drill. It differs favorably from its counterparts by the presence of an autonomous power source. For operation, nickel-cadmium, nickel-metal hydride, and lithium-ion batteries are used. Battery weight is proportional to performance. The scope of application is varied. Suitable for drilling drywall, plastic, wood, profiles and solid metal structures. |
| For diamond drilling | Electrical products. Features high performance. Allows you to drill holes in durable materials. The manufacturer equipped his brainchild with special diamond crowns. To make 60mm holes, the tool does not need to be fixed. You can make a water supply to cool the cartridge. Dry drilling requires the presence of dust extraction systems. Significant loads are controlled by special automatic systems. |
| Drills - mixers | They perform the main task - mixing liquid and bulk materials. Equipped with a powerful electric motor. Available with power reducer. Torque is high. Which product is better to buy? Two-speed products are considered the best. The main area of use is mixing adhesives, paints, varnishes, putties, plaster mixtures, and other construction solutions and liquids. Indispensable for finishing and painting work. |
Let's look at the last type of drill in more detail.
Tips for vertical drilling
Experienced users recommend adhering to the following guidelines when working with a drill:
- When drilling timber for dowels, a stand should be used to secure the tool. A kind of tripod maintains the vertical position of the drill and makes the carpenter’s work easier.
- To maintain the vertical, the right angle is constantly controlled using a carpenter's square.
- To avoid chipping at the exit of the holes, any wooden block should be placed under the main workpiece.
- When working with a drill, if possible, it is necessary to fix the part with a vice.
- If it is necessary to control the depth of the hole, and the drill or drill bit is not equipped with a built-in limiter, then the required distance is marked directly on the drill using electrical tape. This will help stop the drill in time.
When drilling deep holes in wood, the main thing is to firmly hold the stop handle of the tool Source Multicom.by
Purpose of a low-speed drill
These models are also called shockless or low-speed devices. What is the unit for? It is used when there is no need to use devices with a high number of engine speeds. Equipped with low power electric motors. The function of the construction mixer is as follows:
- Mixing bulk components to prepare a solution.
- Thread cutting at low speed and high power.
- Pipe flaring. The process allows one pipe to be inserted into another. Special rolling attachments are required for operation.
- Making holes with a large diameter.
A drill mixer can be used to perform a huge amount of work. At the same time, the products do not heat up, which makes it possible to operate them without interruption for a long time.
Instead of an epilogue
A low-speed drill is a tool in the arsenal of professional builders, so its choice should always be based on the principles of necessity and quality. Such devices, thanks to the reduced rotation speed, show very decent power. Using this equipment, it is possible to mix concrete and make large-diameter holes in solid material. Also, low-speed electric drills are also good because when performing large volumes of work they are slightly susceptible to overheating.
Main product characteristics
To avoid making mistakes when choosing, you must carefully read the characteristics of the device. These include:
- Maximum rpm and torque. The number of revolutions per minute ranges from 120 to 1500. Almost all products are equipped with special regulators designed to switch modes. What should you pay attention to? A high torque implies a low shaft rotation speed.
- Power. Affects the performance of the device. According to buyers, it is worth looking out for models with power from 700 to 1800 W.
- Product weight. Mixer drills are not lightweight. Own weight is 2.5 – 8 kg.
- Chuck and drill diameter. The maximum value is 16 mm.
- Number of speeds. Varies from 1 to 5.
Manufactured products are divided into two categories:
- lightweight (power does not exceed 1 kW);
- heavy (power over 1 kW).
The positive points include:
- master safety;
- comfort during operation;
- flexibility to adapt to a specific task;
- overload protection;
- significant work resource.
Equipment
Different models of diamond drills differ from each other in weight. Some instruments weigh 5 kilograms, and some 12 or more. Therefore, heavy instruments are purchased complete with machines or stands. Drill stands are usually sold separately but are designed for specific models.
If the master plans to purchase a stand for the drill, then you should pay attention to several parameters:
- Availability of angular adjustment.
- Wall mounting method.
- Method of fastening the stand at the treatment site.
- The presence of a rigid gear rack.
- Lifting height when drilling.
- Availability of transport wheels (for ease of movement) + rubber-coated handle for transportation.
How to choose the right tool
The selection criteria for all masters are different. Much depends on how serious the work remains to be done. If you need to start decorating your own apartment, then it is enough to purchase a lightweight mechanism with a power of 0.7 to 1 kW. To carry out major repairs, experts advise giving preference to more powerful models.
Which company is better to buy a product depends on personal preferences. It is worth looking for products from the world's leading manufacturers who value their reputation and do not produce products of questionable quality. You can overpay for reliability and safety. Branded products are not budget friendly.
It’s a different matter for unfamiliar companies. Even bright commercials should not confuse the master. Behind a beautiful appearance there may be a useless thing hidden.
Much attention should be paid to the set of attachments. Almost all devices have spindles with standard threads. The best option is when the drill is additionally equipped with a clutch with a mechanism that does not require a key to clamp it. The drill and mixer for this unit are easy to select.
The weight of the structure is of no small importance. The larger it is, the more difficult it is to work with the device. Your arms will get very tired in a few hours, and you will have to take long breaks to recuperate. When purchasing a product at a specialized retail outlet, it is better to hold it in your hands. This will help you understand how convenient it will be to work with the device.
It would not be superfluous to install modern electronics on the product. This guarantees ease of use and safety. If it is possible to change operating modes, this will have a positive effect on the service life of the product. There are models with a pressure sensor on the start button. The more force is applied to press, the more actively the unit works.
Where to buy the product? Experts recommend visiting a company store, getting acquainted with the assortment presented, viewing the new products on offer, understanding what it costs, and deciding on the package. It is advisable that the product be sold in a case. This is the best option for storing and transporting tools.
You can order the product online in the online store. It is necessary to first view the photo of the offered product presented for review, study the review of reviews, and check the supplier for integrity. Thus, it is better to buy inexpensive mechanisms. Expensive products should be purchased in branded stores. This is a guarantee that you will become the owner of a high-quality original product, and not a cheap Chinese counterfeit.

Circular drill
Masters call this device a ballerina, since the principle of operation of the drill resembles the movements of a dancer. The cutting element consists of a central drill and additional cutters located on a common axis. The position of the cuts can be changed, thereby adjusting the diameter of the future hole. The circular drill set includes a punch intended for marking and a hexagon required for fixing the drills.
The result of drilling using a circular ballerina drill Source Piko-train.ru
A cutting element of this type is chosen in the following situations:
- when it is necessary to drill holes of small depth, the radius of which varies from 15 mm to 65 mm;
- when working with plywood, wood, chipboard, fiberboard and similar materials. Mostly workpieces with a cross section of up to 20 mm or sheet products are processed.
Drilling with a circular element is best done with a low power drill, since there is a high probability of damage to the device.
