Low-speed drill: appointment, which lead to overheating of the gasoline or diesel engine, manufacturers

July 30, 2020

Low-speed drill belongs to the category of professional construction tools. Due to the small number of revolutions and huge power, this device is used for mixing concrete and drilling large diameter holes in solid materials..

Appointment

The low-speed drill is designed to work in cases, when high torque in the tool is strictly contraindicated. Such cases include:

  • threading;
  • mixing mixtures;
  • drilling large holes;
  • flaring of pipes.

Pipe flaring is the process of pipe deformation, during which there is a tight connection between the pipe and the pipe lattice.

When the volume of work is large enough, due to low torque and high power, this drill does not overheat. Performing such work with ordinary tools can lead not only to overheating, but also engine burnout. Because low-speed drills are quite heavy, they, usually, equipped with two handles.

Main characteristics

Low-speed drill has the following main characteristics:

  • tool power - from 900 Tue to 1600 tue;
  • number of revolutions per minute - 400-650 rpm;
  • weight - 3-4,5 kg;
  • number of operating modes - 1-3;
  • drilling diameter - up to 28 mm

Low-speed drill can withstand heavy loads for a long time. Due to these qualities, it is used for large-scale work.

Knead the glue with a low-speed drill

All drills should be divided according to the type of intended load.

  1. Light devices - for small interior decoration. Average power 700-1000 W.
  2. Heavy machines - for large construction works. Average power 1000-1500 W.

Choosing a new tool, you should pay attention to the process of selecting the necessary characteristics. The higher the power, the higher the weight of the device and, in accordance, which lead to overheating of the gasoline or diesel engine.

Drill mixer

Special mention should be made of a professional drill-mixer tool, which combines the functions of a low-speed drill and a mixer for mixing viscous solutions. Usually, such models belong to the high price category.

Due to the presence of various nozzles, high power and mode switch, such a tool is able to perform as percussive work on drilling concrete walls and other strong structures, and mix different mixtures.

Choosing a powerful low-speed drill, you should also pay attention to its weight and the maximum diameter of drilling holes.

An important criterion for selection is the presence of modern electronics on drill mixers. In addition to the obvious convenience and security, the ability to change modes of operation will allow you to extend the life of your equipment. Some models are equipped with a force sensor on the start button. The stronger the pressure on the button, the greater the number of revolutions the device begins to emit. This is also true for the opposite situation.

The main advantages of tools, equipped with an electronic system can be attributed:

  • convenience;
  • security;
  • extended service life;
  • overload protection.

How to choose a nozzle

If for any reason the device is not included, important to know, how to choose it correctly. Most models have a special standard spindle thread, which allows you to securely fix the nozzle. This standard has been adopted by many major manufacturers and, now, it will not be difficult to choose the appropriate nozzle.

Many models are equipped with a movable coupling with a self-tightening mechanism. The key for such tools is not required, and the diameter of the drill or stirrer can be selected independently, using information, specified in the operating instructions.

Movable coupling with self-tightening mechanism

The maximum size of the nozzle is set by the manufacturer. This figure depends on the technical characteristics of the device.
