Polkruhový uhlomer KS Tools 300.0700 Nerezová oceľ Matný 220 mm

The KS Tools half-circle protractor 300.0700 is a stainless steel measuring instrument with a matte finish, designed for accurate angle measurement in workshops, construction sites and hobby applications. With an overall length of 220 mm and a width of 90 mm, the protractor provides a stable footprint and a clearly visible scale for setting and checking angles. Its stainless steel construction gives corrosion resistance and durability for repeated professional use.

Advantages

The stainless steel body with matte finishing reduces reflections and improves scale readability under bright lighting. The half-circle design concentrates measurement graduations in a compact form factor while the 220 mm radius offers finer resolution than smaller models. Robust construction ensures dimensional stability and long service life, and the flat profile allows easy placement against edges and surfaces for accurate alignment.

Suitable for

• Carpentry and cabinet making for checking and marking angles
• Metalworking and fabrication for layout and inspection
• Technical drawing and drafting where manual angle measurement is required
• DIY projects, repairs and installations needing precise angle checks

Key specifications

• Material: stainless steel with matte finish
• Shape: half-circle protractor
• Overall length: 220 mm
• Width: 90 mm
• Scale: engraved angle graduations for precise reading
• Profile: flat, low-profile edge for stable placement

How to use

Place the flat edge of the protractor against the reference surface or edge of the workpiece so the center point aligns with the pivot or marking origin. Read the required angle directly from the engraved scale and mark the workpiece using a suitable scriber or pencil. For transferring angles, align one side with the reference and rotate the protractor until the desired degree aligns with the marking point, then trace the second line. Use steady pressure to keep the tool flush to the surface to avoid parallax error when reading the scale.

Recommendations

Keep the protractor clean and dry after use to preserve the matte finish and prevent surface contamination. Store flat or hung to avoid bending. When measuring on painted or delicate surfaces, protect the finish underneath the protractor edge to avoid marring. For highest accuracy, verify the zero alignment on a known straight edge before critical measurements.
