Best Angle Grinder Buying Guide
With a plethora of options available on market, many people get overwhelmed when choosing the best angle grinder for their need. What to look for when buying an angle grinder, how would anyone know if the grinder can fulfill his needs, is the price appropriate for the given features?
As DIY enthusiasts, we know how it feels when your hand tool doesn’t serve you properly. It will lead to bad quality of work and probably more time in fixing the errors. That’s why compiling a buying guide of each and every feature you should look for while buying an angle grinder wasn’t just a pastime. In fact, it’s important for us to share the knowledge so that our fellow hand tool guys can save themselves a lot of extra works, and an extra afternoon to spend with the family.
Let’s take a look at the features.
There are various uses of a grinder. As the name suggests, the most common use is, of course, grinding or sanding away bulging, uninvited stone, metal or mortar. Construction workers use an angle grinder to make notches or cuts when working with metal or tiles. Bars, rods, and bolts can be cut easily using an angle grinder.
An angular grinder can be used for metal cleaning. If you have a more than 5 years old car, which passes season after season of snow, rain, and heat, then nothing can you do about the car unless you have an angular grinder at hand. A wide range of corroded metal can be stripped, cleaned, deburred using angle grinders.
Why bother to buy a new tool when you can make your used ones running like they were bought yesterday? Tools those need a sharp cutting edge to perform their task well requires frequent sharpening. An angular grinder can restore cutting edges of tools like shovels, hoes, ice scrapers, lawn mower blades, hatchets.
An angular grinder can be used for removing paints from the wall or any metal. Unlike hammer and chisel, an angular grind will not break the brick. The task is dusty so don’t forget to wear a mask and protective clothes.
There are different types of wheels suitable for different tasks. In fact, it’s the main thing you should keep in mind. Without having the right wheel and the right machine to support that, your purchase is pretty much useless. Although almost all of the grinders are made for all types of wheels, make sure you know which one is used for which purpose.
- Diamond- Cutting stones, concretes, tiles or other hard metals.
- Brush- Cleaning and deburring metals, removing rust.
- Aluminum- Cutting bolt, rod, bars, or wood and polishing. Great for woodworking.
- Flapper- Used for sharpening, sanding, restoring edges of knives or other sharp edged tools.
- Silicon- removing mortar and sharpening, rounding and cleaning tasks.
- Fiber- Used to remove rust and burrs from metal.
The size of your disk depends on what type of work you’re going to do. Large disks make it easy to do large and heavy jobs. On the other hand, a small disk is suitable for precise and detailed work. Small disks allow you to explore tiny corners without damaging the machine. Small grinders are available in 4.5 inches and 5 inches size, usually enough for home projects. Professionals and construction workers may need a bigger size of 7 inches or more.
Each angle grinder comes in different wattage, voltage and amp ratings. Grinders with a stronger motor are capable of working with harder materials. While grinders with weaker and smaller motors are built for working with softer materials. Angle grinders come in different watt ratings, ranging from 500-2500 watts. The Voltage ratings are generally between 110-230 volts.
The most important numeric value to determine how powerful your grinder is the amp rating. Amp ratings usually travel within 4 to 15. While the lower rating is sufficient for household works, professional workers need higher amp rating in the grinder.
The rotating speed is measured by RPM, which means revolution per minute. Best angular grinders provide speed ranging from 5000 RPM to 10000 RPM. Obviously, the more speed a grinder provides, the quicker your job gets done. But keep in mind that quicker grinder is harder to control that the slower ones. And faster ones tend to heat quickly.
Your grinder should have an ergonomic design that provides you with comfort. The comfort generally depends upon two things, the size, and the weight. If you intend to use the grinder for a long time simultaneously, you might want a smaller unit. Also, the grip should be comfortable enough to hold it for a long time. The grip should be anti- vibrant so that the vibration doesn’t travel back to your hand.
More powerful motor means more weight. Although power is needed, a hefty weight will make it tough for the worker to hold it continuously. Make sure you make a balance between these two.
Some grinders come with side handles. Although that’s not a must have feature, side handle is really helpful for better control and precision. Some grinders have detachable side handles that can be attached to the right or left, depending upon whether it’s used by a right-handed or a left-handed person.
Safety is important while using tools like an angle grinder. An angular grinder requires a great speed to perform its job well and without safety precautions, that might be dangerous.
Some people like to use angle grinders without the adjustable guard, thinking this will help to work freely. Honestly, I prefer otherwise. The guard is there for a reason and that is to protect you from speedy byproducts. Also, the guard is called adjustable because it can be adjusted to facilitate you to work at different angles.
Make sure your grinder has a “dead man switch’, which prevents the grinder from starting by accidentally pressing the start switch. It will be needed to turn the dead man switch off before working again after an interval, which is a nice mechanism to ensure your safety.
Also, your grinder should contain an electric brake system. The mechanism will shut off the grinder automatically in 2 seconds or less if the machine gets overheated.
Dust ejection, paddle switches, spindle locks are some of the other features that not only keep you safe but also your machine by making it last longer and operate smoothly.
Just like you wouldn’t need a sports car if you live in an area where traffic congestion are rampant, you do not need high power motor for every job. If you need an angular grinder for house use or light jobs, purchasing a grinder that has the highest power won’t make sense, because you’ll never use full power. If you are just looking for replacing your conventional sand paper to remove paint, go for a lower power grinder if you’re looking for some high-end grinding and cutting task, go for a higher motor.
The price depends on many things. The more features the grinder comes with, the pricier it is. Also brand and warranty play a role. You need to pick the best angular grinder that comes within your budget and fulfill your requirements.
Brand And Warranty
Don’t get me wrong, I’m not against new brands coming in the market and providing quality products. The thing is, popular brands are popular for a reason. They are widely discussed and under a lot of scrutiny in forms of reviews, ratings, discussions. The risk of them being bad quality is very low. Yes, there might be a chance that you can get a faulty product accidentally or a product that didn’t work out well for you. In this case, you can use the warranty, replace and refund policy the trusted brands offer and take seriously.
An angle grinder can excel or ruin your work. Angle grinders operate at a high speed, which means if your grinder doesn’t perform well, your work is most probably ruined too. That’s why buying the best angle grinder is necessary.
A grinder needs to be powerful enough to support your type of work. It should have ample RPM for the job. The grinder should start slowly and should have security features like auto on/off in case of overheating. The handle should provide enough grip to hold with comfort.
When you’re going to buy an angle grinder, look for those features. The good news is, the market is competitive and Companies are trying to come up with the best features for the cheapest price. The bad news is, the low-quality grinders are hard to identify from this crowd. This guide will help you with this and you’ll find your grinding mate in this top 10 list of ours. Let us know which one worked for you the best.
