Electrical Angle Grinder

Angle Grinder can cutthrough metal and a variety ofmaterials with ease, but eachmaterial requires the use of aunique disc attachment.
Angle grinders are handheld power tools that, depending on the blade or attachment used, can grind, buff, polish, cut, sharpen, and clean a wide variety of materials, including wood, metal, tile, and stone.  The best for most DIYers are 4 1/2-inch disc models.  Look for high torque, wattage (or voltage for battery operated ones), and variable speeds if you want top-notch results.  These features make an angle grinder the most suited for common uses.
