Bricks are tough and dense materials that make drilling through them difficult. This is because bricks are often much harder than wood or metal and can be layered in such a way that makes it quite tough for the drill bit to penetrate all the way through them.
Drilling through brick requires a lot of persistence, as the bit can take several long passes to get the job done.
Furthermore, drilling too quickly can cause the bit to overheat and may even break it. Therefore, it is important to go slow and steady when tackling a hole in brickwork for best results.
