When most workshop guys think about grinders, they picture the hand-held angle grinder. This multifunctional power tool is used to do many things, such as cutting iron tubing to fix a damaged valve, making furniture, or cutting tile for a backsplash.
With technological advancement, professional power tool usage is rapidly shifting to cordless power, and as a result, cordless angle grinders are becoming more popular. The ability to work autonomously from a steady power source is highly desirable. This means that you don’t need to be tied down by power cords or wires, and can easily access hard-to-reach places. An angle grinder wheel can make it much easier to work with metal, wood, and stone.
We have compiled a list if quality cordless angle grinders available for 2022 so you can add this versatile tool into your toolbox.
Finding Your Next Cordless Angle Grinder: A Buyers Guide
Everyone has different needs when it comes to buying a cordless anglegrinder. People have different preferences. Some prefer grinders to be strong enough to do heavy-duty work. Others prefer that they be comfortable and ergonomic for long periods of time. These factors will help you choose the right grinder for you. So, here are some features of a cordlessangle grinderand how they affectperformance.
There Are A Few Things You Should Consider When Buying A Cordless Angle Grinder
Disc Size
Angle grinders come in a variety of sizes. Each size is identified by the maximum diameter of the grinding discor wheel it can handle. A 4, 4.5, or 13 cm disc will work for the majority. For DIY projects, it is better to use smaller discs and lighter weights as they can be more cumbersome or take up too much time.
In industrial settings, professionals typically utilize larger discs (up to nine inches) when cutting through thick chunks of material. Discs larger in diameter require grinders that can withstand greater cutting forces. You will need a heavier tool to cut larger discs. This will wear your hands more quickly than an angle grinder.
Speed
The rpm of an angle grinder is the standard for describing its speed (rpm). While some grinders are capable of reaching speeds up to 12,000 rpm while others operate at speeds between 5,000 and 10,000 rpm. The rpm is calculated under no load conditions. This means that the disc is spinning in the air and not cutting or grinding anything. The speed drops drastically when the disc begins cutting or grinding.
Higher rpm means that the tool can cut material more quickly and efficiently, but it also indicates that there is a greater risk of injury from the discs’ potential to burst as they heat up faster. Pay attention to the discs maximum supported speed and use the appropriate disc for the job. For instance, if you run a disc that is only supposed to withstand 7,500 rpm at a quicker speed, it may shatter and send pieces of the grinder wheel flying.
Voltage/Amperage
The power output potential of angle grinders is measured in volts (V) and amperes (A) (amps). The power of a cordless angle grinders battery is measured in volts. Most cordless models have 18-volt or 20-volt batteries, but some have 7.5-volt or even 24-volt batteries. The best combination of price and utility is 18-20 volts for most cordless power tools.
Handguard
The angle grinders guard is a very important safety feature covering half of the disc. Its job is to protect the users hands by stopping sparks and other debris from flying at them. It also keeps surfaces from getting damaged when working in tight spaces.
The guards on some angle grinders are movable, whereas, on others, it is permanently attached. Because it can protect the user from projectiles in both directions, and can be used with either hand, the adjustable model is preferred. A removable guard can come loose if bolts are not secured. In contrast to removable guards, fixed guards are more secure and wont fall off using a grinder.
Soft start
Angle grinders may resuscitate slightly when they start up, as they are fast and powerful tools. This is especially true for large and heavy wheels. The motors recoil can cause the angle grinder to jump in the users hands, leading to possible serious injury. Soft-start technology reduces the output power of the motor at first, but gradually increases until it is fully functional. This power regulation reduces the jolt to the users arms and wrists and keeps thegrinder from recoiling during start-up, improving safety.
