About this item

  • 【High-precision geometry drawing tools 】 This set uses zinc alloy steel compasses to ensure stability and no deviation during drawing, while the PS material triangle and protractor are both light and durable. All parts are precision-machined, and the compass joints are designed with anti-loosening screws to maintain adjustment accuracy for a long time. The surface of the metal parts is treated with anti-rust coating to avoid oxidation and rust even with frequent use
  • 【13-piece Math Geometry Kit Set - Meet all scene needs 】 The set includes: 3 specifications of compasses, 1 ruler pen tip, 1 blunt fixed pen tip, 1 extension rod, 2B special lead + automatic pencil, 15cm/6-inch double-scale ruler, 45°&60° triangle, 180° protractor (cm/inch double standard), all components are stored in a pressure-resistant engineering plastic box with a custom sponge groove embedded to prevent transportation collision
  • 【Ergonomic design - comfortable and accurate drawing experience 】 The compass handle adopts a non-slip thread design, so your hands will not get tired even if you draw for a long time. The edge of the protractor is laser engraved with scale lines (accuracy up to 0.5mm), and the matte anti-glare surface ensures clear reading. The specially designed double-bearing rotating structure allows the compass to be precisely adjusted with one hand, drawing a perfect circle from a minimum of 5mm to a maximum of 40cm
  • 【Multi-field professional application - from classroom to construction site 】 Math Protractor Compass meets: architectural drawing (precise drawing of plan/elevation), engineering surveying (drawing of three views of mechanical parts), teaching demonstration (mathematical geometry drawing teaching), DIY design (model making/art creation), especially suitable for STEM education, and the no-sharp-edge design ensures students' safety
  • 【Patented extension rod design 】 Innovative modular extension rod system: ① Complete assembly in 3 seconds through the magnetic quick-release interface ② After extension, it supports compass drawing with a maximum diameter of 40cm ③ Equipped with an angle locking knob to prevent sliding offset ④ Compatible with mainstream brands on the market to replace lead cores
