Buying Guide

Choosing a perfect tool for your work is a tedious job and there are many factors to consider before splashing your hard-earned money.

To buy the best angle grinder or the perfect varying speed angle grinder, you need to do your homework and look into the different features offered by the products.

We are going to discuss some of the most important aspects of buying the perfect grinder. Here are some things you should know about.


The most important feature of an angle grinder is the amount of power the motor can generate. If the motor is not powerful enough or lacks some Amperes or Wattages, it will not be able to accomplish the speed required to do some heavy-duty grinding. Vice versa if the motor is too powerful or is designed specifically for heavy-duty workload, it will not be able to do delicate work.

So, choosing the right motor is a crucial step and one must be clear on what sort of work needs to be done and how much power is required for that work.

Typically, these angle grinders have relatively powerful motors which help them do from simple to the most daunting tasks with ease.


After the motor size, the next thing to consider is the amount of rotation per minute (rpm) a varying speed angle grinder can achieve. The speed determines the nature of the job the machine will be able to do.

speed of angle grinder

For example: In jobs like normal grinding or cutting any material, a grinder with a lesser speed works perfectly fine but for jobs such as polishing, a much higher speed angle grinder is required.

Normally, an average multi-speed angle grinder can range from 2,500 rpm to 10,000 rpm. The rule of the thumb is the more variation in RPM, the more versatile the machine is.

But the speed of such an angle grinder will be as good as the motor it carries which means that a variable speed grinder can go up to 10,000 RPM but if the motor it carries is not powerful enough, it will never be able to work optimum condition.

Motor Type

There are two types of motors available in varying speed angle grinders, Brushless and Brushed. The brushless motor is considered to be more powerful and gives an excellent performance but its costs are much higher than the brushed ones.

On the contrary, brushed motors do need maintenance over time but are much cheaper and give the best performance.

This is solely at the discretion of the buyer to choose the motor type. If the buyer can afford to splash out some extra dollars then it is suggested to go for the brushless motor as it gives an amazing performance and the maintenance cost is very minimum.

But if the buyer cannot afford to put in some extra money or even if the buyer wants to play safe, then it is suggested to buy the brushed motor as it will cost much cheaper than the brushless one and most importantly, it is the most common type of motor available in a multi-speed angle grinder.

Disc Size

Another important factor to take into consideration for buying such an angle grinder is the size of the disc as most devices come with a variety of disc sizes. Disc Sizes can vary between 4” to 6” for small projects or 5” to 7” for tougher tasks.

The disc size is relative to the buyer depending upon the nature of work required from such angle grinders and the disc can creates spark while cutting metal or polishing metal. Some tasks such as cutting a tile or grinding wood require smaller disc sizes of not more than 5” so in this case an angle grinder with a disc size between 4” to 6” will be perfect.

On the other hand, cutting larger surface areas or doing jobs such as polishing, sharpening blade require larger disc sizes like 5.5” to 6” so in this case a grinder with disc size ranging between 5” to 7” will be the best choice.

Power Source

These Angle Grinders are either powered by electricity or run by batteries. If the device is run on batteries, then the need for a cord is discarded. But the downside to these battery-operated devices is that the batteries wear out very fast and you need to charge them often and sometimes between jobs as well.

Power angle grinder

On the other hand, electric-powered angle grinders are more common and preferred over battery-powered ones but the user needs to be near a power source to operate the grinder.

So, even though battery-operated multi-speed angle grinders are easy to use and very portable, electric-powered multi-speed angle grinders are the preferred choice due to their availability factor and because they tend to be more powerful than the battery-operated ones.

Safety Features

Another important aspect to consider before buying a varying speed angle grinder is the number of safety features it provides. A multi-speed angle grinder is an extremely fast and dangerous tool, so the safety features are a must thing to consider.

Features such as adjustable speed dials, soft/light start mechanism, and kickback prevention should be considered before purchasing. These features make or break a product.

Devices like these need to be safety-proof as one mistake can lead to fatal/nonfatal injuries.

Design and Comfort

As already mentioned, a multi-speed angle grinder is an extremely fast tool so the design of the grinder is a vital aspect to consider. Handle designs and ergonomics of a device helps control the grinder with a better grip and help control the vibration.

These design features help the user control the angle grinder with much precision and ease, increasing productivity and efficiency. Users who use such angle grinders for prolonged use, always prefer a device that has a better grip and handling in order to avoid fatigue and tiredness.

The value of a varying speed angle grinder varies from brand to brand. A premium angle grinder from a reputable manufacturer will cost significantly more than a basic grinder.

Sometimes, these hefty price tags are justified by the number of features and durability the device gives but you should always look at all the aspects of a device before purchasing rather than focusing just on a brand name or high price.

There are numerous products available in the market which have amazing features and outstanding quality but lack a proper brand name due to which such devices are priced lower than the branded ones.

The buyer should always check out prior reviews of the product rather than just going for the brand name before taking the plunge.

Warranty and After-Sale Service

This aspect of buying a an angle grinder gives the buyer peace of mind. Warranties usually cover the damage to the device caused by some uncertain situations. This is a way to protect the user by the manufacturer if different mechanisms of the device are damaged or get faulty. Normally, reputable brands provide much better after-sales service and warranty claims than unknown ones.


Is a variable speed angle grinder worth it?

Yes. A variable speed angle grinder is worth your investment as you get more control over the device and can use it for various applications that a normal angle grinder is not able to do such as polishing and buffing.

How many watts is a good angle grinder?

Higher wattage means the higher performance of an angle grinder. A low wattage angle grinder will not be able to perform tedious tasks such as cutting through denser materials. Normally, 500W to 1000W is considered to be good enough power for a good angle grinder.
