8. Maped Study Metal Set

• Material Type: Metal, Plastic
• Weight: 2.4 oz

Best for: Students drawing larger circles.

Why it ranks #8: The ten-piece set lists two metal compasses that draw circles up to 10 inches, two triangles, a six-inch ruler, and a four-inch protractor.

Two metal compasses capable of drawing circles up to 10 inches in diameter distinguish the Maped Study 10-piece set for geometry work that exceeds small-circle exercises. Two triangles, a 6-inch ruler, and a 4-inch protractor add core measuring references for advanced students handling precise geometric tasks.

The two metal compasses’ stated capacity of up to 10-inch diameter circles supports larger circle constructions than a basic small-radius exercise. The 45° and 30°/60° triangles provide two common angle references, while the 6-inch ruler and 4-inch protractor support straight measurement and angle work. The 10-piece designation signals a compact toolkit, but the supplied details do not enumerate the full contents or specify a storage case, so check the listed components against your needs.

Skip it if you need a stated case for carrying the tools; Arcjunys’s compass set includes an iron storage box.

This Maped Helix set suits advanced students who need larger circle capacity alongside standard angle tools. The available product details do not specify storage, so that is an important fit consideration.
