Die grinders are commonly used for metalworking, to rework dies, polish metal, remove rust, sharpen blades and even smooth out surfaces. Like most rotary tools, die grinders spin at a high speed to remove material from your workpiece, be it metal, plastic, or wood.
What Should You Consider in a Die Grinder?
With any power tool, safety should be a top priority. Die grinders also have different attachments to accomplish different tasks, so consider the material you will be working with before purchasing this tool. Some die grinders come with impact resistance and safety locks to prevent accidents. Electric die grinders need to be plugged into an outlet, but cordless ones need to spend time charging.
