Introduction

If you are you planning to add a grinder to your list of power tools at your home, it is important to consider some factors before making a quick purchase. Why? There are several types of grinders on the market, and it’s not a surprise to get overwhelmed when trying to pick the best grinder.

Whether you want to use it for removing dust, cutting concrete or cutting metal, you need a grinder that functions properly. Buying the right tool will enable you to handle your tasks more comfortably, but if the tool doesn’t have the best features then using it could be stressful.

Are you a beginner and wondering what to look for to buy the best grinder? Don’t worry. You are at the right place to find out everything you need to know. These factors will help you make an informed decision before making any purchase.

Grinder Disc Size

There are various disc sizes available from small sizes to large ones. Each size is ideal for a particular application. This means that you need to know what you intend to use the grinder for before purchasing.

While a small disc size less than 7 inches is suitable for most applications, a grinder with a large disc size is more effective for bigger depth and larger surfaces. This is because the larger the disc, the more powerful of a motor is in the tool.

However, it does not mean that it is mandatory to buy a grinder with the largest disc but settle into one that suits your type of job. The most popular disc sizes available in the market are 4.5 inches and 9 inches.

Grinders with small disc sizes are ideal for lighter jobs because it allows more precision compared to a medium-sized grinder.

Grinder Speed

Before making any purchase, you should check the speed of the disc. It’s no doubt that you will be disappointed to take home a tool that will take ages to fix a single problem. The higher the number of disc rotations, the more effective your power tool. The recommended rotations usually range from 1,000 to 5,000 revolutions per minute.

With such a high number of disc revolutions, the grinder is perfect in grinding and cutting. Always take your time in settling on a grinder with the highest number of disc revolutions. Besides, you may want to consider the tool’s n.

Common speeds range from 700 to 1,200 revolutions for per minute. However, there are grinders in the market with no – load speed of up to 12,000 revolutions per minute.

Grinder Motor Power

What is motor power? It is the amount of energy the grinder needs to function effectively. The amp, voltage, and wattage usually vary from one grinder to the other. Considering the amount of current when purchasing a grinder, you can comfortably go for the ones with volts ranging from 110 to 230 volts and wattage ranges of 500 to 2,500 Watts.

In addition to that, you should consider the unit’s amp rating that usually ranges from 4 to 15. That said, you should keep in mind these numbers directly correlate with the power produced by the motor.

Motors with low ratings are perfect for common household tasks that are generally light. While on the other hand, complex and heavy projects require grinders with more amps.

Grinder Wattage

If you want a grinder that produces a lot of power, consider one that has a higher wattage. Note that the more the power the grinder has, the easier it becomes for your tool to grind or cut any object that comes into contact.

A grinder with a big disc needs more wattage, unlike those with small discs. Besides, you should ensure that your power tool has a high amp to allow you to do some heavy projects effectively.

Grinder Soft Start

No one wants a power tool that takes an extended period to start. On that note, the soft start feature enables you to handle your tool comfortably when starting and preventing it from wrenching.

It is also important to keep in mind that the motor should be in high speed before using it on any object. Just because the machine is easy to start doesn’t imply that you should use it immediately upon starting it.

This feature is very crucial when purchasing small grinders because large grinders usually have a soft start feature.

Grinder Adjustable Guard

When shopping for a grinder, check that your power tool has an adjustable guard. The feature will protect you from the sparks and debris that are produced when grinding or cutting material.

Additionally, these guards are usually adjustable and suitable for any available job. Like when doing any job, your safety should be your primary concern which makes the guard an essential feature when looking for the best grinder.

Grinder Handle

To make your work easier when using the power tool, settle for one that has an adjustable handle. It will enable you to operate the grinder using both of your hands.

Besides, be keen to check if the handle contains an anti-vibration feature. It will enable you to use the grinder for a long period without getting exhausted or stressed. Furthermore, the anti-vibration handle will allow you to operate the tool even better.

Comfort

Just like any other power tool, any best grinder should be comfortable to handle. The two main factors that largely affect the comfort of your grinder is its weight and size. When purchasing the best grinder on the market, the two factors go hand in hand.

Unless you want a grinder for large projects or industrial use, going for the smaller units is always comfortable. Compact units are usually easier to hold for a long period, but grinders that have anti-vibration handles provide even more comfort.
