Best metal cutting disc for angle grinder Buying guide
Metal cutting discs come in various types, sizes, and shapes to fit different types of angle grinders. The most important thing to consider when choosing a metal cutting disc for your angle grinder is the type of material you are cutting. Different types of metal will require different cutting discs. For example, steel will require a different type of disc than aluminum. Additionally, a disc designed for cutting steel may not be ideal for cutting aluminum.
The size of the disc is also important and should match the size of the angle grinder. Generally, angle grinders come in 4-inch, 4.5-inch, 5-inch, and 6-inch sizes. The larger the angle grinder, the larger the disc should be.
The thickness of the disc is also important. Thinner discs are more flexible, allowing them to make tighter turns, while thicker discs are more rigid, allowing them to cut harder materials. Thicker discs are also more durable and can withstand more abuse.
Finally, you should consider the type of abrasive material used in the disc. Generally, discs are made with either aluminum oxide or zirconia alumina abrasive. Aluminum oxide discs are best suited for cutting softer metals, while zirconia alumina discs are best for cutting harder metals.
When choosing a metal cutting disc for your angle grinder, make sure to consider the type of material you are cutting, the size and thickness of the disc,
