Each 4.5 inch grinding stone starts with the internal reinforcement of high tensile strength fiberglass mesh. The grinder discs comes together with premium A24T aluminum oxide grains, providing increased hardness. The increased hardness makes the wheel grind away material quicker without sacrificing the abrasive of the wheel itself meaning it can take a beating even during the toughest jobs. Meant to be attached to a 4.5" angle grinder, this 4.5” grinding disk is the perfect abrasive wheel for general grinding, rust removal, removing weld splatter or even rust removal. Use this 4-1/2” x 1/4" x 5/8”-11 hubbed grinding rock on steel, structural steel, all ferrous metals, iron pipe, metal tubing or bar stock. Additionally, this 4.5 inch grinder wheels come with an easy screw on hub attachment. The hub eliminates the need for a flange attachment that the non-hub grinding wheels require.

How well they grind to cut an edge.I have been using them to sharpen mower blades and they work well for the job.I have 6 scares I have to mow every 5 days to keep from having so much grass cuttings that it gets completely unmanageable and having sharp blades on the mower is the only way to cut right through it

The worst grinding wheels I have ever used. They turn into flying projectiles. Beware. I have used this brand for 6 inch cutting wheels and am very happy with those, just not the grinding wheels.
