Best Angle Grinders Buying Guide
Purchasing the best angle grinders for home or construction site is a simple objective. However, several considerations need to be put in mind owing to the myriad of options available on the market today.
Budget Vs. Your Needs
The market flaunts angle grinders at all prices. You’ll find some grinders at prices as low as 30 bucks and others at over 300 dollars. If you need a grinder for some light tasks around your home, cheap electricity-powered units should suffice.
Unfortunately, most of the lowly-priced units limit what you can do with them. They also tend to break down easily- you get what you pay for, remember? As such, it’s worth paying the extra cost for a unit that has good performance, durability, and safety. See more top grinders.
Angle grinder types and their cost
Depending on their power source, angle grinders are of 3 types;
Gas-powered angle grinders– like it’s always the case with gas-powered equipment, these are the best angle grinders regarding power. They are also big and can handle heavy tasks with much precision. These units are best suited for cutting, bricks, steel, and blocks. Given their complexity, these units require lots of experience to work with. The best gas-powered grinders are thus ideal for construction sites.
Electric angle grinders– corded angle grinders are your best shot if you want a tool for light to medium tasks. These units are relatively affordable than gas-powered and the pneumatic models. They use electricity from wall sockets, generators, and even from batteries. In most instances, electric angle grinders are super compact, light and easily portable. These features make them ideal for moving to different work sites.
Compressed air/ Pneumatic grinders– also known as air grinders, these tools use compressed air as their source of power. They are more powerful than electric grinders and a bit more expensive. Air grinders are most common in auto shops. They are ideal for general high-speed polishing, cleaning tire molding, and grinding in confined areas.
Key features to check out for when purchasing the best angle grinders
Disc diameter/size
Angle grinders vary in terms of the size of their discs. Grinder discs range from 4.5 inches through 9 inches. As a general rule, large discs are ideal for cutting larger surfaces and bigger depths. Large discs measure 7 to 9 inches. On the other hand, small discs 4.5-6 are good for smaller jobs.
Rotation per Minute
Usually indicated as RPM, this refers to the number of rotations that the motor turns the blade in a minute. Angle grinders vary in this too. The slowest grinders make around 2000 rpm. The fastest can go as high as 10,000 rpm.
Usually, the higher the RPMs, the faster the blade will cut. Unfortunately, high-speed angle grinders also tend to overheat easily. This may affect the tool’s performance or even destroy it. Low-speed grinders aren’t as fast as high-speed units. However, they are easy to operate and don’t produce a lot of noise and heat.
Fortunately, manufacturers are pushing grinders with adjustable speeds. This feature helps in working on different types of surfaces with just the required amount of heat.
Motor amp rating
It’s also important to understand the motor’s strength. Worth noting, small grinders are, more often than not, faster than large grinders. Motors with a high amp rating will spin faster than those with a lower rating.
Safety features worth checking out
The best angle grinders are among the most versatile tools in a workshop. However, they could also be the most dangerous when misused. The most common accidents with these tools include exploding discs, kickback, and metal chips lodging into your skin and eyes. Some safety features to check out for include;
Variable speed
People who are new to the use of these tools can easily get injured by them. The good idea is to start the machine at the lowest speed and adjust slowly.
Anti-vibration handle
This feature makes the tool more maneuverable. This reduces the chances of accidents. Anti-vibration handles also contribute to your comforts.
Electric brakes
You might also want to go for a tool with brakes. A grinder making around 7000 RPMs can be so dangerous. Luckily, some have brakes that stop them in about 2 seconds.
Adjustable protective guard
The best angle grinders produce a lot of dust and chips at high speeds. As such, you might want to go for a tool that has an adjustable guard. This guard reduces the number of chips coming your way. In addition to this, it’s important to put a dust mask and heavy workshop gloves on.
Adjustable side handles
Two things that affect the affect the ease of using an angle grinder are its size and weight. However, this greatly changes if the tool has a movable side handle. This feature means that you can use the grinder with either hand. A switchable side handle also makes the tool more versatile.
