Transcript of Cordless Power Tools

History of Cordless Tools
Black and Decker invented a cordless drill in 1961. It ran on batteries made of nickel and cadmium.
Because of their ability to be used without power outlets and extension cords, cordless tools are a good choice for a place where outlets are not available, such as the site where a house is being built.
Conclusion
From the first cordless drill to the abundance of tools today which rely on batteries for power, cordless tools have come a long way. They have become vital to carpenters due to their ability to be used without power outlets. They can help save time and space, making them good tools to have.

Taking a Closer Look at Cordless Tools
In a nutshell, cordless tools are the same device as their corded counterparts. The only difference is that a battery supplies the electricity needed instead of an outlet.
Since then, batteries for tools have been made with nickel metal hydride and lithium ion in order to become lighter and have greater capacity. In 1988, Black and Decker created a universal charger which could charge batteries of different voltages. In 1994 DeWalt released a set of over 30 cordless power tools, including a 14.4 volt drill and 5 3/8" circular saw. Nowadays jigsaws, reciprocating saws, drills, impact drivers, oscillating multitools, and pneumatic nailguns are just some of the tools that can be operated cordlessly.
Both tools operate the same way and do the same
task. The cordless model, however does not need a
power outlet because the battery provides the
electricity to get the job done.
This good side about cordless tools also leads to a
small problem. Depending on the type of battery
and its capacity, these tools can only run for a
certain amount of time before the battery must
be recharged.
Another disadvantage of cordless
power tools is that they tend to cost
more than their corded counterparts.
Practical Application
In contrast, the battery life causes it to not be the best choice in a factory, where things are being mass-produced and power outlets are available. In this scenario, corded tools are better for the job.
When purchasing your own cordless tools, be sure to consider the brand as well as the capacity and type of battery. This will help you select the best tool possible. Popular Mechanics believes Milwaukee makes the best cordless circular saw, while Makita produces the best cordless drill. It is also a good idea to consider price and how much the tool will be used when buying any cordless tool.
Thank You For Watching!!
Also, you want to know size of the tools you will need. For example, you should research size, weight, and torque. You also should find the type of handle you would prefer for using the tool you want.
Batteries also need to be replaced after a while because once they are charged a certain number of times, the batteries can no longer hold a charge. Replacement batteries can cost 40 to 100 dollars depending on the type of battery and its capacity.
