Advancements in brushless motors in cordless impact drivers have helped to generate more power while keeping the temperature in check. The battery life and motors have been improved to make these tools work more efficiently.
What to Look for in your Cordless Impact Driver
When buying a cordless impact driver, take note of the following:
The fact that an impact driver is cordless means it uses batteries to generate power. The best battery to use with a cordless impact driver is Lithium-ion battery. These batteries can hold charge for longer and charge up faster than Nickel Cadmium batteries. Lithium ion batteries also don’t weigh as much as the other batteries so they make your tool lighter. Pay special attention to the battery of any impact driver you wish to purchase to make sure you get the most out of the tool.
One of the benefits of using a cordless power tool is the flexibility and convenience that comes with it. If these qualities are compromised by size, the comfort level will be reduced greatly.
Cordless impact drivers have tremendous improvements that have seen these tools become more efficient and lighter with more power. One advantage of using cordless impact wrench is the ability to use then one handed and to operate them in tight corners.
Match the workload with the size of the tool you are about to purchase. If your project requires installing several hundred screws, a larger tool will suffice. If the task is a small one, then a smaller impact wrench will do just fine.
RPM stands for revolutions per minute. The higher the RPM, the faster the tool drives. Cordless impact drivers produce more RPMs than standard drills for heavy duty jobs. The increased RPM gives more force to the bit making the job go faster.
Brushless motors allow for multiple speed settings, speed selector and runs longer on a singer charge. Brushless motors make use of outer electromagnets that sends current to the inner magnet. Its internal circuit is used so there is no need for carbon brushes. Electromagnetic loss is greatly reduced and the efficiency of the tool is greatly enhanced.
A cordless impact driver with brushless motors may cost more initially but you save more on the long run with these motors.
Many top rated impact drivers now come equipped with LED lights to make working in the dark a lot more easier. Some drivers LED powered meters to indicate battery life. LED shines brighter than regular bulbs and takes less of the battery power.
