How to Safely Use an Electric Angle Grinder Electric angle grinder(https://www.konshinegroup.com/product/hardware-tools/angle-grinder-series/) is a very practical electric tool that plays an important role in fields such as metal processing, wood processing, and stone processing. However, safety issues cannot be ignored when using electric angle grinders. Before using the electric angle grinder, it is necessary to inspect it. Check if the power cord is intact, the plug is secure, the grinding head is securely installed, and there are no signs of damage or wear. If any problems are found, they should be stopped immediately and repaired or replaced. This is an important step to ensure the safety of using an electric angle grinder. Choosing the appropriate grinding head and grinding disc is also very important. Different materials require the use of different types of grinding heads and discs. For example, metal processing requires the use of grinding wheels, wood processing requires the use of woodworking grinding heads, and stone processing requires the use of stone grinding heads. The use of inappropriate grinding heads and discs not only affects the machining effect, but may also lead to accidents.
