Technical Field

[0001] The utility model relates to the technical field of cutting protective covers for angle grinders, and specifically relates to a cutting protective cover for an angle grinder. Background Art

[0002] Among many power tools, the electric angle grinder is quite widely used. Besides being used for cutting profiles and pipes of stainless steel, alloy steel, and ordinary carbon steel, or grinding the burrs, welds of workpieces, and large-diameter stainless steel after plasma cutting, it can also cut building materials such as bricks, stones, and asbestos corrugated boards by replacing with a special grinding wheel; replacing with a round wire brush or sand disc can be used for rust removal and sanding the metal surface; replacing with a polishing wheel can polish the surfaces of various materials. In order to prevent the generated debris from flying everywhere, a protective cover is provided on the angle grinder. The protective cover is generally semi-circular in shape, and the debris is blocked and then flies out from the other semi-circular direction, thus ensuring the safety of the operator.
