Deli geometry compass set 8604

The Deli Geometry Compass Set 8604 is a durable, precision-engineered drafting and mathematical drawing instrument tailored for students, teachers, architects, and technical draftsmen. Manufactured with a sturdy metal alloy body, this compass provides the weight and structural stability needed to draw clean, accurate circles and arcs without leg-flexing, slipping, or unwanted diameter shifts. It features an ergonomic top grip designed for smooth, single-handed rotation and firm pivot control. The set includes a precision-sharpened center needle for steady anchoring and a dedicated lead clamp holding a replaceable 2mm graphite refill. Housed in a shatter-resistant, compact clear plastic storage case complete with an extra tube of replacement leads, this tool keeps school bags organized while safeguarding the needle and lead tip from damage during daily transit.

How to Use:

1. Open the plastic storage case and remove the compass.

2. Insert a 2mm lead piece into the pencil holder leg and tighten the screw clamp securely, aligning the lead tip slightly shorter than or level with the steel needle.

3. Lightly sharpen or bevel the exposed lead using a sandpaper pointer or the built-in lead pointer if needed.

4. Set your desired radius by adjusting the angle of the compass legs against a metric ruler.

5. Place the steel anchor point firmly at your center mark on the paper.

6. Hold the compass by the top turn-knob, lean it slightly in the direction of the rotation, and spin it smoothly 360 degrees to draft a clean, crisp circle.

7. Return the compass and lead container to the molded slots inside the hard case after use to protect the sharp needle.
