Review KEUFFEL ESSER CO Co. Drafting Triangle Inch 30/60/90 57 And Long Scale Ruler

The **Keuffel & Esser 0220-6 Drafting Triangle (30/60/90) with T0203 57-Scale Ruler** is a meticulously crafted, professional-grade drafting instrument designed for precision, durability, and versatility in technical drawing, architectural design, and engineering applications. Engineered by Keuffel & Esser, a brand synonymous with uncompromising quality since 1838, this set combines the timeless reliability of a 30-60-90 drafting triangle with the practicality of a 57-scale ruler, all housed in a robust, aluminum construction that ensures long-lasting performance. The 30/60/90 triangle is a fundamental tool for creating accurate angles, whether constructing parallel lines, bisecting angles, or laying out geometric shapes with mathematical precision. Its three distinct faces each marked with precise graduations allow draftsmen to quickly and confidently establish angles of 30 , 60 , and 90 , making it indispensable for both freehand sketching and scaled technical drawings. The included **T0203 57-scale ruler**, featuring a 12-inch (305 mm) length, offers a versatile measuring and drawing tool with a fine, clear scale marked in both inches and millimeters, complete with fractional and decimal subdivisions for meticulous work. The 57-scale, in particular, is a favorite among engineers and architects for its ability to facilitate quick, accurate measurements and proportional scaling, reducing the need for additional conversion tools. The ruler s flat, polished surface ensures smooth gliding across drafting paper, while its sturdy aluminum body resists warping and wear, maintaining straight edges and sharp corners over years of use. Together, these components form a seamless drafting duo, ideal for professionals who demand both efficiency and accuracy in their work. Whether used in a drafting studio, engineering office, or architectural firm, this set embodies the precision and craftsmanship expected from Keuffel & Esser, making it a staple in the toolkit of any detail-oriented creator.

#### **Cons**

1. **Higher Initial Cost**

Compared to basic plastic or lower-grade metal drafting triangles, this tool is more expensive. While it is an investment, the long-term durability justifies the price for professionals.

2. **Weight and Bulk**

The aluminum construction makes the triangle heavier than plastic alternatives, which may be less convenient for students or casual users who frequently move their tools.

3. **Maintenance Requirements**

While durable, the aluminum surface can develop scratches or oxidation over time if not stored properly. It requires occasional cleaning with a soft cloth to maintain its appearance and functionality.

4. **Limited Use for Non-Professionals**

If you are not a professional drafter, architect, or engineer, the precision and cost may not be justified. For hobbyists or students, a cheaper plastic triangle might suffice.

5. **Potential for Overkill in Basic Tasks**

For simple sketching or light drafting, the advanced features of this triangle may not be necessary, making it an unnecessary expense for beginners.

### **Conclusion**

The Keuffel & Esser 0220-6 Drafting Triangle with T0203 Scale Ruler is an exceptional tool for professionals who require precision, durability, and versatility in their work. Its high-quality construction, accuracy, and compatibility with other drafting tools make it a worthwhile investment for architects, engineers, and technical drafters. However, for students, hobbyists, or those on a tight budget, the cost and weight may not be justified, and a more affordable alternative might be preferable.

### **Recommendation**

- **Buy it if:** You are a professional drafter, architect, engineer, or someone who frequently engages in technical drawing requiring high precision. The long-term durability and accuracy will outweigh the initial cost.

- **Skip it if:** You are a student, hobbyist, or occasional user who does not need professional-grade tools. In that case, a budget-friendly plastic triangle or a basic metal triangle would be more practical.

- **Consider alternatives:** If you want a middle-ground option, look for mid-range drafting triangles from reputable brands like Rotring or Staedtler, which offer a balance between quality and cost.
