## Summary description

KOH-I-NOOR Kątomierz 360/125 (174139) is a 360-degree protractor with a 125 mm diameter designed for measuring and drawing angles. The transparent circular protractor provides full-circle angular measurement, degree markings for precision, and is suitable for technical drawing, drafting, education, geometry exercises, and general angle measurement tasks.

## Long description

KOH-I-NOOR Kątomierz 360/125 (174139) is a circular, transparent protractor with a 360° scale and a 125 mm diameter designed for measuring and drawing angles with clarity and ease. The full-circle design allows continuous angular measurement around a central point, while printed degree markings enable accurate reading for technical drawing, school geometry, drafting, and general angle-checking tasks. The transparent construction helps align the protractor with drawing lines and templates without obscuring the work surface.
Advantages
The protractor combines a full 360° scale with a compact 125 mm diameter, offering both completeness of measurement and portability. Clear degree graduations and a transparent body support precise alignment and minimize parallax when reading angles. Lightweight construction makes it suitable for classroom use and fieldwork, while the circular shape eliminates the need to rotate the workpiece to measure reflex or acute angles. The tool is compatible with pencil, fine-tip pen, and technical drawing instruments.
Suitable for
Technical drawing and drafting
School geometry lessons and exercises
Architectural and engineering sketches
Hobby crafts that require angle measurement
Quick angle checks in workshops and on-site measurements
Key specifications
Angular range: 360 degrees
Diameter: 125 mm
Material: transparent plastic for clear visibility
Graduation: degree markings for each degree with numbered intervals
Form factor: circular protractor for full-circle measurement
How to use
Place the central hole or reference point of the protractor over the vertex of the angle to be measured. Align one marking or baseline of the protractor with one side of the angle, then read the degree value where the other side intersects the scale. For drawing an angle, mark the center, rotate the protractor to the desired degree on the scale, and draw a line through the corresponding graduation. Use a sharp pencil or fine-tip pen for precise marks and ensure the protractor lies flat on the surface to avoid parallax errors.
Usage recommendations
Store the protractor flat or in a protective sleeve to prevent bending or scratching. Clean with a soft cloth and mild detergent if necessary. Avoid exposing the plastic to high temperatures or direct sunlight for extended periods to prevent warping. For increased precision in technical work, use in combination with a ruler or drafting triangle.
