As the name suggests, an angle grinder is a tool mainly used for grinding surfaces or parts. This type of grinder can also be used for cutting and polishing purposes. A wide variety of these tools exist, ranging from small hand-held grinders to large grinders used for commercial activities. All different types of angle grinders have different purposes, such as cutting glass. Therefore, it is necessary to ascertain what kind of angle grinder disc meets your requirements. Keep in mind factors such as size, power, safety, and speed before investing in an angle grinder disc. The following section will discuss in great detail what sort of angle grinder disc is the best option for a specific job.
1. Grit Discs
Grit discs are among the cheapest available options in terms of an angle grinder. Such discs are relatively thinner (around 6 mm) compared to other grinding discs. They are mainly used to cut substances such as stone and metal. There are a number of advantages grit discs have over the other kinds. They are able to cut at a relatively quick speed. A grit disc grinder is not a heavy item, and it can be easily held when working up on a ladder, for instance.
2. Diamond Discs
Diamond discs are far more superior than the one mentioned above. They are mainly used for the same purposes of cutting and grinding, but they do so much quicker than grit discs. In terms of cost, diamond discs have now become much more affordable, and even the most basic diamond disc will last longer than the grit disc. Diamond discs are also proven to be safer to use given that it is unlikely the steel disc will fall off.
3. Wire Wheel
The above discs are mainly used for the purpose of grinding and cutting, but the wire wheel disc is used for polishing and removing rust and paint. Therefore, if you need to get metallic rusting and paint off any object, a wire wheel disc is your best shot. Ensure that the object it is used on is hard enough, or the wire wheel could break the object.
Even within wire wheels, there are many different types. The most effective one is the twisted wire wheel, and the least effective is the cup brush type, which you should avoid.
4. Wood Discs
As the name implies, these discs are used to cut wood. However, picking a disc that only cuts wood tends to greatly reduce its usefulness. So it is best to buy a wooden disc that is also capable of cutting steel if a nail comes in the wood. There are many different types of wooden discs that exist in the market, but the more popular one is known as arbortech which is very efficient in cutting wood.
When purchasing discs for an angle grinder, consider what material you are working on and what your end goal is. There are plenty of options on the market to suit every need.
