Cordless Work

Cordless drills are designed to work with wooden structures should have a set of mandatory functions: Reverse which allows you to twist the bolts and screws during disassembly. Two speeds – high speed drilling and low – for screwing up. Switch torque, which when properly configured, prevents the excessive tightening of screws deeper into the material. Most cordless screwdrivers are used keyless chuck under the nozzles and drill bits with a maximum diameter of shank 10 mm. Some of the more powerful models cordless drills have a chuck that allows the use of drills with hvotovikom 13 mm.

These models with metal 13mm cartridge usually have a feature hammerdrilling, which hardly has used when working with wood materials, but is essential for drilling holes in lightweight concrete. The latest developments Cordless use “smart” chargers, that help increase battery life by optimization method of charging. These chargers for almost a full battery switch to a limited, fractional mode, which allows the maximum charge the battery. Many models have screwdrivers Included Parts two batteries. It is necessary for continuous prolonged operation screwdriver until one battery runs the other . For example a German company Festool and Protool Czechoslovak firms to fully charge the battery used 30 minutes of time! It’s good that the market represented a lot of models screwdrivers meet these requirements.

But how to choose a screwdriver? The two important parameters for the remaining equity. First, When you choose a screwdriver to power suitable for solving your problems to pay attention not only on battery power. Batteries with the same voltage is not the same. Comparing the accumulator batteries the same voltage charging current ratio aware at the time – A / hr. Battery with a large ratio of A / hour hold charge longer. The second factor which must take into account when choosing a cordless screwdriver – easy to work. Hold Drill in various positions including the position of the head, as if you are tightening the screws into the ceiling. Ask yourself questions: Is it convenient? Balanced if Screwdriver? How long will I be able to work this screwdriver screwing the screws into the ceiling? If the screwdriver simply too heavy to work for 30 seconds in such an awkward position, probably should look for an instrument with a lower operating voltage, and as a consequence of less weight and size. Cordless Drill must be powerful and easy to use. If you do not find a drill handy, you do not like her work.
