The DIY industry continues to grow in America, with experts estimating that it is now worth $74 billion. Whether you’re undertaking construction projects as an amateur or a professional, you’ll always need the right tools at your disposal. If you’re working with metal, a flap disc will be an essential part of your kit.
Read on as we explain how to use a flap disc.
What Is a Flap Disc?
A flap disc is a circular attachment for an angle grinder. It is used for a number of functions in metalwork, including surface finishing, blending, and stock removal. They do some of the same jobs as grinding wheels, which you may be more familiar with. However, there are some important differences. A flap disc is a lighter fixture than a grinding wheel. It is better for more delicate tasks, such as finishing and blending.
While you can also use flap discs for metal removal, they are not as efficient in this role as grinding wheels. Flap discs will wear out more quickly when doing this kind of work. Flap discs also vibrate less than grinding wheels, resulting in less fatigue for the user.
How to Pick the Right Flap Disc
There are different kinds of flap disc. The decision about which one to choose should be dictated by the type of project you’re undertaking. Your primary considerations will be grit type and grit size.
There are three different grit types:
- Ceramic alumina
- Zirconia alumina
- Aluminum oxide
Ceramic alumina is the premium option and is used on most professional projects. Aluminum oxide is the cheapest of the three. Zirconia alumina is a blend of the other two. Grit sizes range from 24 to 120. Your choice here will be based on the type of work you want to do with the disc. The more delicate the job is, the higher you should go with your grit size. Grit sizes of 24-60 are used for grinding and heavy stock removal, while 80-120 are used for jobs like blending and finishing.
Flap discs are delicate, so you will have to be careful when storing them. Firstly, ensure that you store them on a flat surface. If possible, store your flap disc in its original container. You need to make sure your flap disc stays dry, so always keep it away from containers of water or other liquids. As well as this, make sure to store it in a room that stays between 60-80 degrees Fahrenheit. The room should not have excessive humidity.
