Characteristic

Special storage conditions are imposed on them, since they have a strong memory effect, therefore, while the devices are not in use, they should be completely discharged. Lithium-ion batteries have no memory effect, they have much more capacity, and the charge is held longer, they are much lighter.

The keyless chuck is standard on all Sturm products, as it saves the user time for tool changes and is much more convenient than a jaw chuck.

It is of two types:

• single-seat;
• two-clutch.

Changing the nozzle with a single-sleeve cartridge is done quickly, with one hand, in the second case, one hand pushes the first sleeve, and the other unscrews the second.

Principle of operation

In the design of cordless and mains screwdrivers there is an engine, on which the operation of the tool depends. The force generated by the motor is first transferred to the gearbox, and then to the spindle.

The clutch integrated in the gearbox is responsible for torque control . The spindle is equipped with a chuck and a holder, on which the equipment is placed. Any nozzle that will be used by the operator is inserted into the chuck and the socket in it. When the energy generated by the motor is converted and amplified, the rig begins its movement at a speed set by a person or at a set number of revolutions.

Model overview

As mentioned above, all Sturm models are divided into two large groups: battery and mains. Battery-type equipment prevails - electric screwdrivers can have a power of 12, 14.4 or 18 volts. Their demand is due to their compactness and mobility.

Electric screwdrivers Sturm CD31181, CD3118C and CD30181 have a nickel-cadmium battery in the design. They are perfect for housework, since they do not have much power, but the manufacturer has provided two rotation speeds, the ability to adjust the speed, reverse.

Selection Tips

Before buying, the user should know that All Sturm screwdrivers can be divided into two large groups:

The advantage of equipment with little functionality is its cost ., while more expensive screwdrivers differ in that they can solve much more complex problems. Battery models differ not only in the type of built-in battery, but also in its capacity. A professional screwdriver of this type should fully replenish the charge in an hour, while a tool for everyday tasks will take about 7 hours.

On expensive models, sometimes there are up to 22 possible adjustments, including - speed, number of revolutions, direction of movement of the drill, backlight, etc. You should definitely pay attention to screwdrivers, which provide the ability to switch between impulse and impact modes.
