Which is the best Corded Angle Grinder?
At times only a corded power tool can do the jobs we need them to. Yes, cordless is the way many power tools are heading, but for a tool like an angle grinder being tethered to a constant power supply is a must. If you’re looking for a cordless angle grinder, click here for our comprehensive guide.
In this guide, we’ll take you through what you should consider before buying a corded angle grinder and we’ll present you with our recommendations for grinders based on the diameter of the discs that fit them.
What is an Angle Grinder used for?
An angle grinder will serve many purposes on the jobsite, from cutting through concrete and steel to removing rust and burrs from metal to buffing and polishing steel. Weigh up the types of applications you intend to perform with your angle grinder, then make a buying decision based on the capabilities, capacities and features of the grinder you’re interested in.
While price is often a key factor when buying any tool, spending a bit more cash to get the type of grinder with the spec and features that will allow you to work safely is important.
One of the advantages of owning an angle grinder is the ability to fit a variety of different types of discs to it in order to be able to perform these different jobs, but it’s important to understand the capacities and limitations of the disc you’re going to be using. Click here to read our guide to making sure you’re staying safe with the discs you’ll fit to your grinder.
It’s worth noting that while grinders capable of higher RPMs are going to allow you to perform heavier applications, it also comes at the risk of injury. So consider any special features related to protecting you – and the tool – from misuse, such as dead-mans switches, the type of disc/wheel guard supplied, anti-vibration side handles, etc.
Advantages of Electric Grinders
As a corded angle grinder is capable of running for long periods of time, the size of the grip and the weight of the tool are other important factors for you to consider. Clearly, a grinder intended for large cuts, for example, will be a powerful beast, that means it’ll often be heavier than a grinder with a smaller disc capacity.
Therefore if you’re only going to be performing light tasks with your grinder, a smaller model – with a smaller diameter disc – is probably the way to go. It’ll be lightweight and easy to hold, and likely more manoeuvrable and controllable into the bargain.
Alternatively, while a grinder with a small disc diameter will typically be light and easy to hold, using it on large-scale projects will quickly become tiring for the simple reason that it will take longer to get the job done than a grinder with a larger disc diameter, even though such a tool may be heavier to hold.
A grinder with great ergonomics will be important, and any efforts on the part of the manufacturer to reduce the amount of hand/arm vibration transmitted to you is another feature to look out for.
