Radius Pointer Compass – High Precision Metal Drawing Compass with Dial Indicator for Geometry, Exam & Technical Drawing

Precision You Can Read at a Glance

Designed for students, architects, and technical illustrators who demand accuracy, this high precision metal drawing compass features a built-in dial indicator that displays the exact radius in real time — no guesswork, no re-measuring.

• 📐 Instant Radius Display: The integrated clock-style dial shows your radius from 2mm to 120mm with a clear, easy-to-read pointer — perfect for exam conditions and professional drafting where speed and accuracy matter.
• 🔩 Durable All-Metal Construction: Built from premium metal alloy that won't bend, warp, or deform under pressure. The anti-slip grooved grip and auxiliary quick-release mechanism give you full control for smooth, consistent circle drawing.
• ✏️ Exam-Ready 0.5mm / 2B Lead: Comes with a 0.5mm mechanical pencil lead insert (2B grade) for crisp, clean lines that are ideal for geometry exams, technical drawings, and architectural sketches. Replacement leads included free.
• 📌 Stable 20° Inward-Bent Pin: The precision-engineered pivot pin is bent inward at 20° to maintain a perfectly vertical centre point — eliminating slip and ensuring every circle is centred exactly where you intend.
• 🎨 Available in Black & White: Sleek, minimalist design in two colourways to suit your style. Compact size (3.3 × 1.1 × 13.8 cm) fits easily into any pencil case or geometry set.

Whether you're sitting a GCSE maths exam, drafting architectural plans, or creating precise geometric artwork, this compass delivers the professional-grade performance you need.
