There are many ways to remove slag and dross, but not all of them are equally effective or efficient. Chipping hammers and similar tools are often used to remove slag, and while they're effective, they're also the slowest option. Angle grinders can also remove slag, which are much faster than using a handheld chipping hammer.Web
