Metal Compass Set – Precision Circle Drawing for Students & Drafters

Whether you're tackling geometry homework, sketching architectural designs, or working on engineering layouts, this professional metal compass set delivers steady, accurate circles and arcs every time. Built from high-strength metal with a locking adjustment screw, it holds your chosen radius firmly so every line stays exactly where you set it. Made in Mainland China.

Key Features

Durable Metal Construction: High-strength, wear-resistant metal body maintains structural integrity through long-term repeated use — no bending, no warping, no need for frequent replacements.
Secure Metal Pencil Clamp: Reinforced clamping arm holds the included wooden pencil firmly in place, preventing slippage mid-stroke for consistent, clean line thickness on every circle and arc.
Locking Adjustment Screw: Solid metal lock screw fixes the compass legs at your preset radius so accidental shifts during drawing are a thing of the past — no more rework from size deviation.
Non-Slip Rubber Grip: Textured matte rubber handle conforms to your fingers, reducing friction and keeping your hand comfortable even during extended drafting sessions.
Shatter-Proof Plastic Storage Case: Hard transparent carrying case protects the compass and pencil from scratches and keeps all pieces together — easy to slip into a backpack for school, the office, or outdoor sketching.
Fits Pens Up to 0.39 Inch (10 mm): Wide clamp opening accommodates most standard pencils and pens for versatile use.

Frequently Asked Questions

Q: What is the maximum pen or pencil diameter this metal compass can hold?

A: The reinforced metal pencil clamp on this compass set accommodates pens and pencils up to 0.39 inches (approximately 10 mm) in diameter, making it compatible with most standard pencils, mechanical pencils, and fine-liner pens commonly used for geometry and drafting.

Q: Does the locking screw really keep the radius from shifting mid-draw?

A: Yes. The solid metal adjustment lock screw is designed to firmly fix the opening angle of the compass legs at your preset radius. Once tightened, the legs stay in position throughout your stroke, preventing accidental displacement and ensuring accurate, repeatable circle sizes.

Q: Is this compass set suitable for both students and professional drafters?

A: Absolutely. The set is designed to serve both students working on geometry assignments and professionals handling basic engineering or architectural drafting. The durable metal build, non-slip rubber grip, and protective carrying case make it reliable and portable for classroom, office, or on-site use.

Q: What comes included in the package?

A: Each set includes one metal compass, one matching wooden pencil, and one hard transparent plastic storage case — everything you need to start drawing precise circles and arcs right out of the box.
