What is a cordless drill / driver? What opportunities does he have? How does this tool differ in battery brothers? What are its pros and cons? This review will tell about all this.
People who are professionally engaged in construction or repair are more likely to prefer to purchase units with certain functions, i.e. separate drill and screwdriver separately. The fact is that the network drill / driver is significantly inferior in speed and quality to the professional tools. However, the home master will be quite satisfied with the set of functions that this unit offers.
Torque
The power drill / driver has its own torque adjustment. Such a function will be important for the master working with various materials - when the resistance changes, the rotation transmission will automatically switch. In addition, the regulator easily switches the work to drilling, for which the torque goes to the drill. To make perfect holes, pick up a drill / driver with a rotation speed of about 1200 rpm.
To screw in the screws, it is enough to have a speed of up to 500 revolutions per minute. The regulator will cope with this task. In addition, unlike a conventional drill, a screwdriver instantly stops without breaking the edges of the hats.
These tools are equipped with a depth gauge for twisting (drilling). This will be very important when assembling and repairing furniture, when performing bulk work. For example, when working with a large amount of drywall, the regulator allows you to reduce the number of "mistakes" to a minimum. The master is not so tired, and the quality of the work performed remains at its best.
Additional functions
Many such units have additional functions that make it easier to complete the tasks assigned to them. For example, the Interskol DU-16 / 1000ER electric drill / driver is equipped with another auxiliary handle, as well as a spotlight.
What's better?
What to prefer: a cordless drill or cordless? The first option has a significant plus - the absence of cords and wires allows you to perform work even in very hard to reach places. In addition, battery devices are much lighter than their counterparts. However, a cordless drill / driver is more powerful; it does not need constant battery replacement. For large volumes, this can be a decisive argument.
It should be remembered that many network devices are much heavier than rechargeable ones. Such a device is undesirable to use when attaching drywall to the ceiling - the hands of the master will not get so tired and numb. However, there are lightweight models - they will become the ideal solution for high-altitude work.
It is undesirable to use a drill screwdriver for working with dry building mixes - too strong and prolonged work of the torque very quickly destroys the tool. It is better to purchase a separately inexpensive mixer for this.
Careful attitude to a screwdriver-drill and its use only for its intended purpose will significantly extend its service life.
