Angle gauges, also known as angle finders, are tools used to measure angles with high precision. They are commonly used in woodworking, metalworking, and other trades where precise angle measurement is required. Angle gauges are available in a variety of styles and materials, including plastic, aluminum, and stainless steel. Some angle gauges have a digital display, while others have a mechanical dial or scale. Angle gauges can measure angles in degrees, radians, or other units of measurement, depending on the specific model. They can be used to measure angles on a variety of surfaces, including flat and curved surfaces, and can be used in both vertical and horizontal orientations.
