With 11 pieces, the Hauser XO Mathematical Drawing Instrument Box centers on zinc alloy metal tools. These instruments resist bending during high-pressure drafting. A 0.7mm mechanical pencil maintains line consistency without sharpening. This version replaces the previous wooden pencil with a mechanical unit and swaps the opaque tin for a transparent plastic case.
Key Features
- Zinc Alloy Instruments: High-precision metallic compass and divider construction. Heavy metal arms prevent the needle from jumping during circle rotation.
- Mechanical Writing Unit: 0.7mm mechanical pencil with a dedicated lead tube. Constant lead diameter eliminates the need for sharpeners during exams.
- See-through Storage: Durable transparent plastic carry case. Visibility allows immediate detection of missing tools before leaving the classroom.
- 11-Piece Kit: Includes 15cm ruler, 180° protractor, and dual set squares. Rigid plastic survives the impact of road dust and heavy bag pressure.
- Silver Matt Finish: Anti-glare coating on all zinc alloy components. Surface treatment prevents fingerprint smudges from obscuring measurement marks.
Frequently Asked Questions
Which geometry box is best for SSC exam?
The Hauser XO suits SSC exams because the zinc alloy compass provides high stability for geometry diagrams. The 0.7mm mechanical pencil maintains the line thickness required for technical accuracy.
What is the benefit of the zinc alloy material?
Zinc alloy offers higher density and weight than standard tin or plastic instruments. This extra mass stops the divider and compass from flexing during high-pressure use.
