Product Information

Full details

The M&G Metal Geometry Compass Set is designed for students, architects, and engineering professionals who require high-level precision in their drafting and geometry work. Built with a solid metal body, it provides exceptional stability for creating perfect circles and arcs, though users should be mindful that its rigid metal construction requires careful handling to maintain the alignment of the precision hinge over long-term use.

FAQs

What is the maximum diameter this compass can draw?

The compass can draw circles with a maximum diameter of 36 cm.

Does this compass come with lead?

The set is designed for use with standard pencil leads, but it is recommended to keep extra lead on hand for your specific drafting needs.

Can I replace the needle point?

The needle point is integrated into the metal body for maximum stability and is not intended to be swapped out.

How do I keep the metal clean?

Use a dry, lint-free cloth to wipe the surface; avoid harsh chemicals that might strip the metal finish.

Is this suitable for young students?

Yes, its durable build makes it excellent for school geometry, though younger students should be supervised due to the sharp needle point.

Troubleshooting

Compass legs slip during use

Tighten the adjustable hinge screw slightly to increase tension on the legs.

Lines are inconsistent or faded

Check that the lead is secured tightly in the adapter and ensure it is sharpened to an appropriate point.

Compass cannot draw a full circle

Ensure the center needle is firmly embedded in the drafting surface to provide a stable pivot point.

Pros and Cons

Pros

  • Durable all-metal build quality
  • Secure hinge keeps radius constant
  • Compatible with standard pencil leads
  • Compact case makes for easy portability
  • Reliable for both math homework and blueprints

Cons

  • Requires manual adjustment for lead tension
  • No built-in lead sharpener included
  • Metal edges may scratch surfaces if dropped

Setup, Compatibility & Care

To set up your compass, first loosen the hinge slightly to find your desired radius, then tighten it to ensure the legs do not drift. When inserting lead into the universal adapter, ensure it is centered to maintain line accuracy. For maintenance, keep the hinge free of dust and debris, as trapped particles can cause grinding. Store the tool in its provided case when not in use to prevent the needle point from dulling and to protect the hinge mechanism from misalignment.
