Angle Grinder Buying Guide

Angle Grinder on the Metal

The cheapest model, a recognized brand, the best offer? They’re all valid options but when it comes to purchasing your angle grinder, how do you really know what you’re getting? Buying a basic model from a recognized brand may be lacking in certain areas, likewise purchasing a lesser-known brand at a fraction of the price may include all the features you require and more! The following guide

What Type of Angle Grinder do I Need?

Before you even cast eyes on an angle grinder it’s important to understand the fundamental differences between the types available on the market, in the end this is all relative to what you will be using it for, what purpose do you want it to serve? There are four main varieties of to choose from, each one is more accustomed to a certain job than the other, this should be you’re first consideration.

Battery Powered Angle Grinder – One of the main things that works in favor of the Battery powered variant is the fact that its cordless, this is not only more convenient than its counterparts but also offers a greater degree of flexibility while you work. The downside is that the battery only has a limited output before it needs to be recharged, so if you’ll be grinding for sustained periods of time it may be wiser to invest in something that has access to mains power to avoid any disruption.

Electrically Powered Angle Grinder – Undeniably the most popular form of grinder, favored by hobbyists and professionals alike, the Electric powered angle grinder utilizes the mains supply to power its motors. Although this gives it an edge in terms of unlimited power and efficient output it does mean that it can only be used with a readily available power source nearby, there are ways and means of getting around this issue though, such as the use of an electrical generator or an extension cable. As it’s so sought after its available in a wide range of models and sizes, this is what makes the Electric powered angle grinder one of the most adaptable, from cutting to grinding, polishing to sharpening, whatever your needs you’re sure to find a suitable electrical angle grinder.

Petrol Powered Angle Grinder – This is really only for use on large-scale projects, think along the lines of construction work, so needless to say they’re heavy duty! The ‘big brother’ of the battery powered angle grinder the petrol variant is also cordless which adds to its versatility. Be careful with this specific type of grinder though, a shower of sparks and a petrol leak don’t make for a good combination, regular maintenance is important – I don’t think I need to say any more!

Pneumatic Angle Grinder – The pneumatic angle grinder is a powerful bit of kit, making full use of its heavy duty, compressed air power source it’s ideal for areas that are hard to reach but still require a lot of power. Quite often the disc size of a pneumatic angle grinder is smaller than others – although larger sizes are readily available. The reason for this is that the small size coupled with the strong pneumatic powered motor lends itself to precision tasks, often vertically mounted as opposed to horizontally the reduced size allows you to work a smaller area to the same degree of accuracy without any loss of power.

Power

Angle grinders are available in varying degrees of power or RPM (revolutions per minute), fortunately for consumers, manufacturers will specify a certain disc size to go with a certain RPM, resulting in an optimum performance level. Use this rule of thumb: The larger the disc size the larger the power output and vice versa. Asides from RPM you will notice that each grinder has a differing degree of wattage, volts and amps, the latter being the one to pay attention to. Grinders can start off with as little as 4 amps, which may be perfectly adequate for small DIY tasks, all the way up to 15 amps, which is for your heavy duty, professional models.

Discs

When deciding what grinder to buy don’t let the discs come into the equation, each of the individual types of grinder will accommodate each variant of disc, although there are different sizes of disc so it’s best to check which diameter size the grinder takes before purchasing. The discs themselves are each designed to work with a specific substrate, so it is possible to work on any material with any angle grinder; it purely comes down to the discs. With that said the power, RPM, and disc size are all critical factors in how long it takes to finish a job and to what standard, so choose wisely.

Safety

It goes without saying that you should take precautionary steps whilst operating any power tool, the same can be said of angle grinders, if not more so. The spinning disc designed to cut through steel like butter can reach speeds of up to 10,000 RPM, so ensuring your grinder has all the necessary handles and guards built into it is a must. Thankfully modern day angle grinders are heavily regulated to ensure just that, one thing you may wish to consider though is who will be operating this machinery, is it just for personal use or will others have access to it? If so you may wish to purchase a grinder with adjustable handles and guards for both left and right handed users.

Selecting which angle grinder to purchase should be an informed decision, using the above information and considering all the requirements should factor into your choice, whether it is the cheapest, the best offer or a recognized brand all these reasons to buy should come secondary, put your needs first and choose what’s right for you.
