You can successfully slice through hardwood material with a three-teeth angle grinder blade as long as you match the rotation of the blade with your grinder. It is a multipurpose 4 1/2 inch angle grinder disc that is great for cutting, carving, sculpting, and shaping wood. The steel body of this disc is coated in black ceramic which provides solid protection from heat and wear. The edge of the disk is beveled which helps to control the flow of material while cutting. There are two types of blades available for your grinder: grinding and cutting. If you plan to only grind material such as wood or metal, then a grinding disc will work well for you. These discs have a wider surface and are designed to move at a slower speed than cutting discs. This allows you to use less power and create a finer finish on your project. If you also want to be able to cut materials with your grinder, then you should get a cutting disc. These discs are narrower and rotate faster than grinding discs. This means you will need more power from your engine to drive the disc. Cutting discs can also be used for rough chopping by rotating the blade quickly multiple times. Angle grinders are easy to use and can cut a wide variety of materials including wood, plastic, metal, and ceramic. Just make sure that you select a model that is suited for the tasks you plan to use it for.
