Description

Technical Field

[0002] A wall grinder is an electric tool that uses an electric motor as its motive force to drive the sand disc on the end face to rotate at high speed to grind and clean the wall surface. Therefore, this grinding method is much more efficient than manual grinding.

[0003] At present, the grinding discs of common grinders are arranged in a circular structure. When grinding the corners of walls, the circular grinding discs cannot grind the corners of walls, resulting in dead corners.
