The Top 10 Power Grinders of 2017

If you make your living with tools or you regularly use them for diy home maintenance, you probably already know that picking out a high-quality one will greatly affect the quality of your work. Today, we will talk about the best power grinders in 2017 to make that decision easier for you.

How To Choose The Right Sized Grinder

Larger Jobs, Bigger Grinder

When talking about a grinder’s size, this is usually measured by the disc part of the machine and not the overall length or size. Of course the handle gets consequently bigger to better control the disc as it increases in size, but disc size is the primary determinant of a grinder’s size. An angle grinder’s most common size for homeowners is 4.5 inches, which is the measurement of the disc’s diameter. That’s because it’s the most efficient for the few odd woodwork jobs around the home. For larger jobs that require an angle grinder, wheel size plays an important role and the necessary size increases as the size of the job increases.

Big Wheels, Deep Cuts

If you need to cut thick and strong materials like concrete and stone, you’ll need a grinder that has a bigger disc size. Even if a smaller grinder manages to cut through your material, you’re going to spend a long time with your project. If you get a grinder with a bigger wheel, the project can be done is less time and with more ease. If you’re dealing with wood as a material, most of the grinder sizes can manage the task, it’s just a matter of thickness in choosing the right grinder size for you.

Small Grinder, Faster Spin

It’s all a matter of simple physics, really. The smaller the disc, the faster it finishes one whole spin. 4.5 inch grinders can reach speeds of over 11,000 RPM. With this speed, these small grinders can accomplish the tasks of cutting and polishing metal. However, with great power comes great setback. Smaller grinders are more susceptible to overheating as compared to their larger siblings. It’s highly recommended to get a grinder with customizable speed settings so as not to keep on using the highest setting all the time. Even though bigger grinders operate at a lower speed, they are less likely to overheat and thus will perform better.

There is, however, a little detail that you should note. The amp rating of the motor also plays a large role in the speed that a grinder can spin. Just to be sure how exactly your grinder is expected to perform, check the RPM rating.

Grinders For Newbies

If you’re new to grinders, it’s best to note the power that this tool possesses. It’s made of metallic discs that are sharp and heavy duty. You can easily see where it might pose a danger to you, especially if you’ve never handled one before. If you’re going to be using a grinder for the first time, the best advice is to start small, and always wear protective gear like a face plate and gloves (for better handling, since the grinder vibrates a lot). Don’t get a bigger grinder and attempt to use it for your first time because you’re still not used to handling one. 7 inch grinders cannot be operated by one hand, so imagine just how things could quickly get out of control. Practice with a small one first to be able to get used to the feeling of using a grinder, then move on to the bigger leagues when you’re ready.

Cordless Grinders

The larger your grinder is, the more power it will require to work. So it’s not uncommon to see large grinders with high powered motors of 110 or 240 volts.  This makes them pretty bulky, and nothing is more inconvenient than trying to reach into a tight workspace only to find out that the cord of your grinder is not long enough. It’s bad enough maneuvering the bulky tool in the first place. So if you see that this is a likely scenario in your near future, you might want to get a smaller grinder. These can operate on a mere 18 volts and often use a rechargeable battery for power. A lot of these are also cordless, so they’re quite convenient to use.

Points To Consider When Choosing One

The Value You Get For The Price

Value, in this sense, refers to the amount of use that you could get out of the grinder that you buy. That usually depends on the extent of work that you’re going to need it for. For home improvement purposes, a 4.5 inch angle grinder can usually get the job done. The general rule is the more specs, the more value you can get from it.

However, this does not mean that you should get the grinder that has the most specs, unless you’re going to find a use for all of those specs. It’s like buying a full kitchen appliance set when you only need a refrigerator: it’s a waste of money if you’re not going to be utilizing all or most of it. Quantity matters, but quality is just as relevant.

Safety

Dust ejection system. Spindle lock. Paddle switch. What are these specs that can often be seen on your standard angle grinder? These are the safety features, and you must keep these in consideration when choosing an angle grinder. Safety has a twofold meaning here: keeping you safe from harm, and protecting your investment with a tool that lasts longer. Find an angle grinder that has features to help keep you from getting exposed to injury like an adjustable guard.

A “dead man switch” is also necessary in the case that you think that the grinder is posing danger to you and to itself.  This ensures that you don’t accidentally turn on the grinder and end up in an accident because of that mistake. Despite the presence of these safety features, it’s still best to wear the proper protective gear when using an angle grinder.

Make and Model

In searching for the right angle grinder, you will see that there are brands that have already established their name in the manufacturing of this power tool. You’ll most likely come across DeWalt, Makita, and Hitachi, all of which are pretty good and trustworthy brands.

Still, it’s going to be tricky choosing the best out of all three, as some of them may over the best quality while the other one offers the best deal and the other one has the best value. It’s all a matter of determining which one really fits your needs at the moment.

Disc Specs

We’ve already established this in the first part of this article: you will have to choose the specs of the disc based on what you’re going to use it for. Less abrasive discs are great for polishing, while more abrasive ones are perfect for cutting and grinding even the most abrasive materials.

At the end of the day, it’s all a matter of understanding the context of the need. Knowing what you’ll be using the grinder for will help you determine the exact type and make that you should be looking for.
