Electric nutrunners Bort: characteristics, features, best models
Content
The electric type device will completely free you from the tedious manual tightening and disassembly of threaded connections. The length of the 4-meter cable allows you to work at a considerable distance from the power source - an electrical outlet with a voltage of 220 V.
It is problematic to manually tighten cylindrical, conical, external and internal threaded connections of triangular, rectangular, round and other shapes. The master requires considerable strength and flair for the moment of tightening. This work is easily handled by a special power tool - a Bort wrench - an indispensable assistant in household chores, car services, and construction sites.
Main characteristics of impact wrenches
The gradation of thread wrapping machines is very large: there are pneumatic, hydraulic, electric models. The latter are divided into network and battery. Regardless of the power supply, there are percussion and unstressed devices.
However, all the variety of equipment has a number of similar characteristics. The first is torque. This is the rotational force measured in Newton meters (Nm). The opinion that the larger this value, the better the Bort wrench is erroneous. Consider the size of the unscrewed fasteners:
- for nuts up to M12, 100 Nm of torque is enough;
- size up to M18 will require 250-350 Nm;
- M20 and above, soured fasteners - from 600 Nm.
Set with a nut driver "Board"
For car repairs, they take a tool with a torque of 800 Nm, for roofing - 300-450 Nm, for small fasteners on thin structures, a peak of 180 Nm is suitable.
The second characteristic of wrenches is the number of revolutions. High performance is needed only in production, where with the help of this device they work all day. Labor productivity depends on turnover. In everyday life, small workshops, it is better to pay attention to the number of strokes. It has to do with the number of turns. A tool with a large number of impacts may strip the fastener head or threads.
The next characteristic is the type of cartridge. Important things to know about this option:
- 1/4 inch hexagon justifies itself in household chores on low power devices;
- 1/2 and 3/8 inch square shapes are the most practical, sought-after option;
- 1" and 3/4" square works with large fasteners.
The type of percussion mechanism is also an important indicator that will not tell a simple user anything, but a lot to a specialist. In this matter, you need to rely on the manufacturer: as a rule, the impact mechanism is optimized with the Bort nutrunner.
When choosing your tool, pay attention to the material of execution (metal, plastic), size, weight, additional equipment. It’s good when there is a backlight, a speed controller, an additional handle, a bracket for hanging the device.
