Network drill-screwdriver. We choose correctly
What is a network drill? What opportunities does it have? What is the difference between battery and battery? What are his pluses and minuses? All this will be told by this review.
People professionally engaged in constructionor repair, most likely, prefer to purchase units with certain functions, i.e. separately a drill and a separate screwdriver. The fact is that the network drill-screwdriver is much inferior in speed and quality of the executed works to professional tools. However, the home master will be quite enough of the set of functions that this unit offers.
Screwdriver-drill network has its own adjustmentof the torque. This function will be important for the master, working with different materials - when changing the resistance, the rotation transfer will automatically switch. In addition, the controller easily switches the work to drilling, for which the torque goes to the drill bit. To make ideal holes, select a screwdriver with a speed of about 1200 rpm.
To screw the screws it is enough to have a speedup to 500 revolutions per minute. The regulator will cope with this task. In addition, unlike a conventional drill, the screwdriver instantly stops, not "breaking" the edges of the hats.
These tools are equipped with a depth limitertwisting (drilling). This will be very important when assembling and repairing furniture, when performing large-scale works. For example, when working with a large amount of drywall, the controller allows you to reduce the number of "bloopers" to a minimum. The master does not get so tired, and the quality of the work done remains high.
Many similar units have additionalfunctions that make it easier to accomplish the tasks assigned to them. For example, drill-screwdriver network "Interskol" ДУ-16 / 1000ЭР is equipped with one more auxiliary handle, and also a spotlight lamp.
What to prefer: a cordless drill or a cordless drill? The first option has a significant plus - the lack of cords and wires allows you to perform work even in very hard to reach places. In addition, batteries are much easier than their counterparts. However, the network drill-screwdriver is more powerful, it does not need constant replacement of batteries. For large volumes, this can be a decisive argument.
It should be remembered that many network devicesmuch heavier than rechargeable. Such a device is undesirable to use when fixing plasterboard on the ceiling - the hands of the master will not be so tired and numb. However, there are lightweight models - they will be the ideal solution for high-altitude work.
It is not advisable to use a screwdriver forwork with dry construction mixtures - too strong and prolonged work of torque very quickly disables the tool. It is better to purchase an inexpensive mixer for this.
Careful attitude to the screwdriver-drills and its use only for its intended purpose will significantly extend its service life.
