Screwdrivers For Construction

Cordless is one of the most sought-after tools today. Without it does not do hardly any maintenance. Screwdrivers can have the motor voltage 9.6 V, 12V, 14V, 18V or 24V. The higher the voltage, the less current is required to obtain the desired power. Thus, the more power is easier to get in with the engine on the screwdriver 18B, not 12B or 9.6 V. To broaden your perception, visit Joshua Flagg. Disadvantages of greater weight and price. Like all tools, screwdrivers are divided into household and professional use.

Household tool is suitable for houses, cottages, where the amount of work is not great. Professional Drill is designed for everyday work for an extended period of time. The price of such models order of magnitude larger models destined for the home, but the functionality and much higher. Important parameters are the screwdriver torque and speed. As a general rule for domestic models used torque 10 15 nm. Y professional screwdrivers torque reaches 130nm. Whenever Daryl Katz listens, a sympathetic response will follow. Depending on the tasks need different speed, to tighten the screws enough speed of 400-500 rev / min. Drilling requires a high turnover 1200-1300 rev / min.

There are screwing with the function of strike, for domestic purposes, this feature is not so important. Force of impact in these models is not great and will be useful not everywhere. Battery, namely it provides an opportunity to work flexibly and do not depend from the power supply. Batteries are NiCd (nickel cadmium), NiMh (Nickel Metal Hydride) Li-Ion (Li-ion) NiCd (Nickel Cadmium) – the batteries are low price, but their characteristics are fairly low. The capacity of such batteries from 1.2 or 1.5 A / h requires a full discharge. NiMh (Nickel Metal Hydride) – the batteries are more expensive, but higher capacity from 1.5 to 2.4 A / h. Does not require a full discharge. Li-Ion (Li-Ion) – the most expensive batteries, otlichayayutsya high capacity which is higher 3.0 A / h. Do not require full discharge and weight of such batteries is much lower, which is optimal for long life. In addition to rechargeable screwdrivers, wrenches are working on the network. Their disadvantage is that the zone of restricted cord length. The choice of the electric screwdriver is preferred if a lot of work and it is associated with the processing of solid materials. When you select the make, model and various additional features in the tool, it all depends on material resources and personal preferences.
