Faber-Castell 174335 Bow Compass Black

The Faber-Castell 174335 bow compass is a precision-engineered tool designed for accurate geometric construction and technical drawing. Featuring a durable black finish and a robust 3D design, this instrument provides the reliability needed for both academic and professional drafting tasks. It is equipped with a high-quality gear wheel adjustment mechanism located in the grooved compass head, ensuring smooth and stable operation when setting the desired radius.

Advantages

This compass stands out due to its combination of sophisticated design and rugged functionality. The gear wheel adjustment allows for precise and quick setting of the circle diameter, while the non-slip needle and secure lead clamps ensure that every line drawn is exact and consistent. Its ergonomic construction makes it comfortable to use for extended periods, and the inclusion of a spare parts tin ensures that users can maintain the tool for long-term performance.

Suitable for

• Technical drafting and architectural design
• Geometric construction in school and college projects
• Artistic drawing requiring precise circular shapes
• General engineering and mathematics assignments

When it may not be suitable

This compass is primarily designed for standard technical and educational drawing tasks. It may not be suitable for large-scale industrial drafting that requires circles significantly larger than 340 mm in diameter. Additionally, users requiring specialized heavy-duty metal compasses for extreme workshop environments might find this model more suited for precision paper-based work rather than heavy construction marking.

Key specifications

• Maximum circle diameter: 340 mm
• Adjustment mechanism: Robust gear wheel
• Design: 3D quick-set
• Included accessories: Spare parts tin with leads
• Origin: Made in Germany

How to use

To use the Faber-Castell bow compass, first ensure the lead and needle are securely fastened in their respective clamps. Adjust the compass legs using the central gear wheel to reach the desired radius, which can be measured against a ruler or by setting the distance between the needle and the lead point. Place the needle firmly on the center point of your intended circle and rotate the compass head smoothly to draw the arc. Always ensure the compass is held by the top handle to maintain stability during the rotation.

What to consider before purchase

• Verify that the 340 mm maximum diameter meets your project requirements.
• Ensure the compass is compatible with standard lead refills if you plan on intensive long-term use.
• Consider the intended application, as this model is optimized for precision drafting rather than heavy-duty industrial use.

Usage recommendations: To maintain the accuracy of your drawings, keep the lead sharp and ensure the needle point is clean. Store the compass in its provided case when not in use to protect the gear mechanism and prevent the needle from becoming blunt or damaging other items.
