The cordless drill is an electric tool that runs on rechargeable batteries.
It doesn't need any electrical power outlet or extension cord to do its job, as long as the battery has charge in it.
This makes it very mobile, capable of working in almost any situations.
Carpenters, electricians, and handymen all love this tool.
Its popularity quickly spawns many other cordless tools that are similar, but more specialized.
Here's a list of some of them.
1.
Cordless Drills This is a rotary tool that can either drill holes or drive fasteners, depending on the bit attachment it uses.
It's also referred to as a cordless drill driver.
They vary in sizes and power capacities.
The power of this tools usually goes by its voltage rating.
It can be a compact model at 7-volt, or a super-hefty model at 36-volt.
The higher the voltage, the more rotational torque power it can produce, and it will be bulkier and heavier, too.
Depending on what type of work on hand, choosing the right power-rating can be the difference between an easy job or tough going.
2.
Hammer Drills.
This tool has a hammering mechanism that can produce hammering impacts while it turns.
This hammering mechanism is engaged when a switch or dial is set to the ON position.
When the hammering mechanism is disengaged, it works exactly like a regular cordless drill.
The hammering action is important when working on brick, or rock, or other kinds of masonry.
It's chipping away as well as scraping away the material.
You will need to use a masonry bit because a regular twist bit gets dull quickly in the masonry material.
This tool is slightly more expensive than the regular tool, but the hammering option is highly worthy of the price.
3.
Impact Drivers The impact driver is similar to the hammer drill.
It also has a hammering or impacting action during operation.
But it's not meant for drilling but for driving only.
Sometimes it's referred to as an impact drill.
Probably because it appears to look like one.
But really it's a fastener driver, as the head can accept only hex-shank screw bits, unlike the other ones which have jaws that can grab on to either a round twist bit or hex screw bit.
The impacting action of this tool, together with its super-high torque motor output, enables it to drive screws quickly and almost effortlessly.
When you want to drive tens and even hundreds of screws in quickly, like when you build a fence or deck or a cabinet, this is a terrific tool for the job.
Especially when the screws are longer than 1 inch.
The impact driver will work much faster than the cordless drill.
