General characteristics of INTERSKOL screwdrivers

All Interskol brand screwdrivers have some differences in characteristics, which is understandable. It depends on some parameters.

What do all models have in common:

• Good power.
• Sustainable torque.
• The bodies of all tools are made of special aluminum alloys, which significantly increases the service life.
• The screwdriver handles are made in compliance with ergonomic rules - the tool fits very comfortably in the hand.
• The DC motor produces high torque. However, the shaft rotation speed, as well as the gearbox speed, remains low, which also increases the tool life.
• All products are relatively inexpensive compared to other brands.

Battery models may differ in both battery voltage and battery type.

Battery

Batteries are available in three types:

Lithium-ion - Li-ion. They are lightweight, fast charging and can withstand almost 3.5 thousand charging cycles. There is no memory effect. Such a battery cannot be completely discharged in order to avoid reducing its working life. The main disadvantage is poor performance at sub-zero temperatures.

Nickel-cadmium - Ni-Cd. “Hard-wearing” elements with high resistance are able to work even at low temperatures (-20 degrees). Charging cycles – 1500. Disadvantage: they take a long time to charge (about eight hours). There is a memory effect. To increase service life, it is not recommended to let the battery reach a completely discharged state.

Combined Ni-MH (hybrid). The number of charging cycles is 550. They work from charge to charge more than the two previous types. It is also not recommended to discharge completely.

Cartridge

A good chuck should securely hold both bits and drills.

There is always a choice of cartridges, which are produced in two types:

• Quick-clamping. The advantage of such cartridges is that it takes a matter of seconds to replace the equipment, and this is extremely important when the technological process requires it. The chucks are equipped with either one or two couplings. Changing drills on a single-sleeve chuck is done with one hand. The latter are additionally equipped with a spindle lock function.
• Hexagonal. This type of chuck allows you to work with bits. The equipment changes in the same time as in the first case. When purchasing such a cartridge, you need to specify the size of the diameter inside the glass, because the size of the nozzle used directly depends on it - usually it is 10 mm.

Additional accessories

To ensure drilling accuracy. You need to use some devices:

1. Conductors.
2. Tripods.
3. Guides.
4. Holders.

Various attachments are used as additional equipment.

Impact mechanism

The impact mechanism greatly facilitates the work, and most of the products presented by Interskol have one. It works in the direction of rotation and provides additional force, thus increasing torque.

This is especially important for drilling brick, concrete, stone and other materials. This also helps in installing fasteners.

The impact mechanism is a kind of compensation for the lack of torque.

Max diameter

The drilling diameter is very important. Depending on the model and chuck, screwdrivers have a maximum drill diameter of 16 mm. Although most people use 10 or 13 - as a rule, this is enough.

Basically, drills and screwdrivers have a maximum drilling diameter of 13 mm. This refers to the largest hole that can be drilled into the steel.

Not every consumer works with large drills, so there is no point in overpaying for a larger chuck.

If the consumer’s chuck does not allow him to clamp a larger drill than it was designed for, then the easiest way is to sharpen the shank of the drill in a lathe, reducing its diameter to the required size.

The maximum drilling diameter in wood is 30 mm. The drill has a much smaller shank, which allows it to be clamped in the chuck without any problems. And the drill itself is a feather drill, the cutting part of which can be either 30 mm or more.

Equipment

The equipment included with a particular tool may vary: additional attachments, flashlights, batteries, etc.

Although on average the contents of the case look like this:

• Screwdriver.
• Warranty card.
• Instructions.
• Batteries.
• Charger.
• Bits.
• Adapter.
• Screwdriver bit.
• Drill.
• Cartridge.
• Case.

The difference is usually in the number of nozzles.
