Best Angle Grinders Buying Guide & FAQ

What to Consider When Buying an Angle Grinder

Not only do tools represent a significant financial investment, but you also need to ensure that they are suitable for the jobs that you have in mind. So, before you rush out to buy an angle grinder, here are a few of the main points that you need to consider.

  • Disc Size

As a rule of thumb, the bigger the size of the angle grinder disc, the more power that the motor will possess. Discs come in a range of different sizes, so you should buy an angle grinder which is suitable for the job – whether you need to cut through big chunks of metal or manoeuver into smaller spots for intricate work.

  • Motor Power

Electricity, petrol, or compressed air are the three most common ways to power an angle grinder. Every one of these tools also comes with a different wattage, voltage, and amp rating. If you need the grinder for bigger, industrial-sized jobs, a stronger motor may well be required. However, if you only need the grinder for simple tasks, a less powerful motor will probably suffice.

  • Dust Management

It is inevitable that you are going to generate a lot of dust and debris whenever you are using an angle grinder, but a high-quality device should be able to deal with this. Not having to worry about all the dust will help to make your jobs just a little bit more straightforward.

  • Comfort

Whenever you are using a power tool, you need to feel entirely comfortable. Not only will you be able to do a much better job, but it will also be safer for you as well. Size and weight are two of the main factors which will impact your comfort. Units which are smaller and more compact are easier to use for an extended period of time. However, larger tools are better for industrial-standard jobs.

The handle of your angle grinder is an important feature which will impact your ability to do the job properly. Adjustable side handles will help you to operate the machine while using both hands. Anti-vibration handles also help to make your task easier and quieter – especially if you need to operate the tool for a long time.

  • Speed Ratings

Angle grinders tend to range between 5,000 to 10,000 rpm, but ones with the highest of speed ratings are best left to the professionals as there is a higher risk of injury if they are not operated correctly. Again, everything comes back to your intended usage. If you only need one for some polishing and maintenance, a lower speed rating may well be good enough, but if you are planning on cutting through metal, a higher rating is the better option.

  • Safety Features

It is worth saying again that choosing a tool which is safe is essential. You will have seen terms like ‘tool-less’ in the product descriptions written above, which allows you to reposition the guard and safety slip clutch. Other safety features include automatic shutdown if you drop the tool. Remember, when you are using something like an angle grinder, safety should be of paramount importance.

  • Interchangeability

A big proportion of angle grinders give you the option of changing discs and adding other accessories as required. So, this means that you can use a single tool for a vast array of purposes. Before you purchase your angle grinder, double check that it supports the intended attachments. If not, you need to look closer at what other options are available to you.

  • Soft Start

Another important feature you should check is if it has a soft start system or not. Essentially, this allows you to start up the machine without it twisting or wrenching. Most larger grinders have this feature, so it is worth checking the smaller ones if you are not sure.

If you want to clean and polish concrete or stone, an angle grinder is also useful in this task.

If you have a floor which needs retiling, your angle grinder can play an invaluable role in this job.

Some of the items that you will need include a long-sleeved shirt, heavy-duty gloves c-clamp, and workbench. Once you have put on your protective equipment, you can then place the metal that you want to cut in your workbench, securing it with the c-clamp. Next, ensure that the grinding wheel is tight on your grinder. Double check that the securing nut is tight. Now, you can turn on the grinder and lower it down slowly onto the metal where you wish to cut it. Take your time and do not force it faster than it will go. Continue until you have got all the way through and turn off the metal grinder.

Q:  How to remove an angle grinder disc?

A:  There are a couple of different ways that you can remove the angle grinder disc. Two flattened wrenches come with many of these tools. The one that looks like a two-pronged fork can be inserted in the drive bolt between the disc and the angle-grinder motor. It should be turned in the opposite direction of the disc direction arrow while using the other wrench to stop it from turning. There may also be a button which holds the disc in place.

Another option is to use improvised spanners. First, you need vice grips to secure the bolt holding the disc to the drive bolt. Using the grips to stop the disc spinning, you can then insert a screwdriver between the disc and the angle-grinder motor. You need to pull it in the converse direction to the arrow on the disc. If you can’t loosen it yourself, you can use a hammer to encourage the screwdriver to turn.

Your final option is to not use any tools at all. First, you should strike the disc in the reverse direction of the arrow on it, loosening the nut enough to take it out with your fingers. If you are unable to do this, you can break the disc off in pieces to get the best access to the attachment nut and bolt.

Q:  Can an angle grinder be used as a polisher?

A:  Using a special polishing wheel attachment or buffer pad, an angle grinder can be used to polish metals such as aluminum back to looking at its best.

However, you will need a variable speed angle grinder on a slower setting or a proper speed controller. Otherwise, you can simply buy a dedicated polisher.
