## Long description

Technical Compass Penword CT-01 — Penword precision drawing compass (model AI632PSH) is a compact drafting instrument designed for precise construction of circles and arcs in technical drawing, engineering sketches and student projects. The compass features a fixed-length arm set that maintains stable measurements during use, a metal construction for durability and a fine adjustment mechanism that permits incremental radius changes for accurate results on paper and drafting film.
Advantages
The metal body provides resistance to wear and maintains consistent geometry over repeated use. The fixed-length arm arrangement reduces play and helps keep radius settings stable while drawing. The fine adjustment mechanism allows smooth, controlled radius changes for precise circle diameters. A pointed metal tip ensures secure anchoring on paper and reduces slippage during rotation, while the pencil-holding end accepts standard leads or mechanical pencil inserts for clean, repeatable lines.
Suitable for
Technical drawing and drafting
Architectural sketches and plans
Engineering diagrams and mechanical design
Student geometry and design exercises
Model making and scale drawing
Key specifications
Construction: metal frame for durability and dimensional stability
Arm type: fixed-length arm set for stable measurements
Adjustment: fine screw mechanism for controlled radius changes
Tip: pointed anchoring tip for secure pivoting on paper
Pencil holder: compatible with standard pencil leads or mechanical pencil inserts
Typical use surface: paper, drafting film, tracing paper
How to use
Place the pointed tip at the intended center point and hold it steadily. Insert a pencil or lead into the pencil holder and secure it at the desired projection. Use the fine adjustment screw to set the required radius, checking the distance between tip and pencil tip. While keeping the pivot tip anchored, rotate the compass smoothly around the center to draw a complete circle or arc. For repeated or precise measurements, recheck the radius after a few rotations and tighten any adjustment if necessary.
Usage recommendations
To maintain accuracy, store the compass in a protective case when not in use, avoid dropping or bending the arms, and periodically check and tighten the adjustment mechanism. Use a sharp pencil lead for the cleanest lines and place a small piece of scrap paper under delicate drafting film to prevent piercing when anchoring the tip.
