A cordless angle grinder is typically used for cutting solid objects into parts or removing the excess slag that often occurs after welding joints together. The grinder can accept many different types of discs, such as grinding wheels, sanding discs, and cut-off wheels.
The battery powered angle grinder is cordless, and therefore not connected to an A/C power source. This makes it portable and easy to use for light-duty applications, also giving more freedom of movements and angles for the workers. Of course, the length of use also becomes limited and spare battery packs are required for extended use, but with voltages as high as 28 volts, they provide plenty of power for tough grinding jobs.
There are many types and brands of the cordless angle grinder on the market. Here are some of the highest rated, and a short review on each.
Makita DGA452Z 18-Volt LXT Lithium-Ion Cordless Grinder
This grinder, while battery-operated, does not typically include the battery in the package. However, when its lithium-ion battery is used, it has twice the cycle of a regular battery, producing 280% life work. Users love the fact that it has an indicator light to serve as a warning when the battery is starting to run low so that it can be removed before it conks out.
If faster grinding is required, this one has that ability, with a motor capable of delivering 10,000 RPM. Its LED protection circuit is built in and can protect the motor from an excess of torque. This is done through flashing a warning light during an impending overload.
When it comes to variety, this grinder is also rather flexible. It is able to sand, grind and cut many different materials such as pipe, conduit, and concrete.
It is very user-friendly because its control is smooth and its pressure even. It is compact and quite light, only 5.6 pounds. Its slide switch has a lock-on capacity, but there are complaints about this switch being a little too touch-sensitive. One must simply exercise caution while using the switch.
PORTER CABLE PCC761B 20-volt MAX Lithium Bare Cut-Off/Grinder
People love this cordless angle grinder because of its slim design and soft grip. The handle, also, is removable. It is lightweight and compact. Comfort and control have never been more clearly defined in a grinder. Its slide switch is easily turned off, which adds to the safety factor of this model. Also for safety purposes is its overhead protection circuit, to guard against surges of currents.
Despite its slimness and comfort, it is actually designed for tough grinding and cutting and does not disappoint in this aspect. It is also surprisingly durable, despite its almost flimsy appearance.
This is a battery powered angle grinder, so it must be used with 18V batteries, which can either be NiCd, NiMH or Lithium ion. Lithium ion batteries are favorable because, like this grinder, they are also very lightweight.
However, this grinder is only recommended for quick jobs. It may not be able to sustain its power for a more heavy-duty job, and in this case, a corded grinder is recommended.
DEWALT DC411B 18-Volt 4-1/2-Inch Cordless Cut-Off Tool
This cut-off tool does not come with its own battery, which should be purchased separately. It has the capacity of 6,500 rpm for cutting and grinding. This means that it has less power than some other grinders, but it also has a strong point- it is a lot more quiet and smooth. This is because its gear alignment is of impeccable precision.
Another of its perks is that its wheels are remarkably easy to remove. Its wheel release enables a quick change. A wrench is not even needed for this purpose.
Its side handle provides the choice of two positions. This enables a higher level of control and comfort for the user. The trigger switch allows for an easy grip because of its lock-off button. It is also very light, weighing in at only 4.6 pounds.
A typical complaint is its dust-kicking tendencies when applied to concrete, however, this is a minor hitch.
Like other cordless grinders, it is not suited for prolonged application. But it does serve its purpose admirably for short-term jobs.

This battery-operated grinder includes a 100mm grinding wheel, and a spindle lock to enable changing of the wheel or setting up with a chosen accessory. It is the perfect solution for situations wherein electricity is not readily available or difficult to access. It does allow until 18 months of storage time on a charge, which is very convenient.

When it comes to simple, household use, this particular model is highly recommended because it works smoothly and easily, not requiring particular technical expertise. The average homemaker will find it very user-friendly. In fact, some who came into possession of it and intended to sell it at first eventually changed their minds due to its usefulness.
Using the Angle Grinder
When you have chosen the preferred angle grinder for your application, you must be familiar with its various functions and capacities.
-First of all, an angle grinder is meant for cutting, and it can be used on a wide variety of materials, depending on which blade you use. For the strongest materials like metal, a diamond-tipped blade is recommended.
-It is handy for polishing metal.
-It is also good for sharpening old and blunt hand tools. Now, those abandoned tools stocked in the work shed or even kitchen cutlery can be spruced up and see the light again.
-For rough sanding, an angle grinder is quite efficient. A sanding pad has to be attached if this is your purpose. It is not, however, recommended for extremely accurate or meticulous sanding jobs.
Because the cordless angle grinder is very affordable, it is a handy tool to own even for home use. It is perfect for a wide range of tasks and the ability to work without an extension cord provides great flexibility and usefulness.
