4. Before mounting the flap disc, ensure the power switch is off and your angle grinder isn’t connected to a power source.
5. You may pick your flap disc based on the sort of wood you have. The sanding paper comes in grits of 40, 60, 80, 100, and 120, so you may choose the correct one for the wood you’re working with and the desired result.
