Types of Angle Grinders

There are two basic types of grinders: cordless and corded, but which style of these is highly versatile. Cordless grinders are convenient, but the downfall to these is that you need to make sure that the batteries are charged. Corded grinders will be more powerful to use, but you will always have to make sure that you are using it or working near an outlet. They are both great options, and each one has different types of grinding styles and attachments you can choose from.

To give you a look into the different styles, here is a list of the most prominent types of grinder you can find.

Surface Grinders

Surface grinders are used to produce a smooth finish on flat surfaces. This type of grinder includes a spinning wheel covered in an abrasive surface to smooth out metallic or wood surfaces. This machine will make a myriad of materials flat and smooth.

Cylindrical Grinders

Cylindrical grinders are grinders that are used to shape the outside of an object. These types of machines can work on a variety of shapes, such as cylinders, ellipses, or crankshafts. Overall, these machines are great to use on anything that needs to be smoothed out that might have a difficult shape to work with.

Centerless Grinders

A centerless grinder is a machine that uses abrasive cutting to remove materials from a piece of work, such as an engine or more difficult to cut machines. These types of grinders work well in an automotive shop setting or really any mechanic work.

Internal Grinders

An internal grinder is a special grinding machine that can grind the internal diameter of a piece. This type of grinder typically uses rollers t process items such as paper, paint, steel, textiles, and some forms of rubber materials.

Angle Grinders

An angle grinder, sometimes known as a side or disc grinder, is a handheld tool that is perfect for grinding and polishing. This type of grinder is able to accommodate all kinds of attachments and is one of the more popular options when it comes to finding a perfect grinding tool.

How to Choose and Angle Grinder

How to Choose and Angle Grinder

While there are so many angle grinders to choose from, you may be wondering how to choose the best one. The following specifications will let you know how to look for a grinder that is ideal for your work and how these functions come into play.

Size

It’s really not so much the size of the tool, but just how powerful it is that matters. There are plenty of compact grinders that will get the job done just as well as a larger grinder that won’t be difficult to hold and maneuver. With that said, the larger grinders will give you more power and are the best to tackle enormous jobs instead of just some jobs around the house. Industrial grinders are best for the installations of flooring for businesses or putting up walls to a home.

Disc Size

The DIY community loves the smaller discs that don’t go past five inches for household projects, but for more serious projects, you’re going to want a larger disc. A larger disc will easily scale a massive job in no time, where a smaller disc could scale the same job but at twice the time it will take. When it comes to larger discs, seven to nine-inch discs are ideal for a larger scale job, but would be way too big for a smaller hobby project, so make sure you are finding the appropriate disc size before tackling the job.

Type

As far as type of grinder, you can choose from corded or cordless, and then choose the exact type of grinder you’d need from the list above. When it comes down to it, you can always buy a standard corded or cordless grinder that can work with varying attachments so you don’t have to invest in one type of grinder that could potentially be good for just one type of job. For example, why buy a surface grinder when you can buy an angle grinder that can accommodate multiple attachments? If you only need a surface grinder for large jobs, then that makes sense, but if you need a grinder to be able to do more functions, then an angle grinder is the way to go.

Usage

Another factor to consider is just how much you plan to use your grinder. If you are using this machine for small jobs around the house, then a smaller, more compact grinder with interchangeable attachments may be your best bet. But, if you are trying to find a large grinder that can easily accommodate a large scale job, or if you work in construction or mechanics, then finding a larger grinder may be your best bet if you plan to use it on a more regular basis. It just depends on what you need and when you need it.

Voltage

Voltage is another option that you might want to explore because a voltage will tell you more or less how powerful your grinder can be. The higher the voltage, the more powerful your machine will be. You will never want to use a grinder that is too powerful for the job as you can easily trip a breaker or even start a fire if you are not careful. Make sure you know how powerful your grinder is before each job and just how much electricity you can generate in the general area.

Cordless Options

Cordless options are great because they are smaller, more compact, and definitely easier to move around with. Cordless options will not be able to tackle a huge job, however, as they tend to run out of battery quickly. The nice things about cordless options is that they are great for smaller home projects where you will only need your grinder for a short time. Plus, the versatility in not being tethered to a certain area makes cordless grinders popular among the DIY community.

Wattage

Kind of in the same vein as voltage, the wattage of your grinder will vary from machine to machine. Always read your electrical safety guidelines on any type of grinder that you buy before use, so you know just how much wattage you are dealing with before the start of any job.
