Shinwa Japanese #19 Stainless Steel Protractor 0-180 degrees with Round Head

Herramienta muy útil en el taller de carpintería para dibujar los ángulos

The accuracy seems excellent, the markings have maybe 0.1~0.2 degrees inaccuracy at most. The edge is perfectly flush at 180 and 0 degrees.One really nice and innovative feature I noticed is that the indicator arm with the measurement mark is ever so slightly bowed in the vertical plane, like a 0.05~0.1 millimetre and only makes contact with the protractor BEHIND the measuring arrow. This means that throughout use, as long as you don't overtighten the locknut while measuring, it will significantly reduce any wear on the indications and measurement marks since it's not making contact with them.The locknut holds the entire thing together so don't overloosen it, a small 1/4 or 1/3 turn is enough and provides that gap underneath. Very happy. No idea where it was made as the packaging doesn't actually mention on mine, but even if it's made in China it's pretty solid quality. Would have liked to have it made in Japan but oh well. The description is incredibly misleading though, the only Japanese thing about this is the brand behind it. Given that that's the only indication anywhere on this page for where it's made I find that misleading as anyone browsing (like me) would assume it's made there.

Precise, high quality marks, good choice of metal material. Overall great choice 👍

Solid well built protractor. As far as I'm able to tell its very accurate as well.

E' costruito molto bene per l'utilizzo in officina meccanica e risponde a pieno al descrittivo dell'annuncio. Consegna come sempre ottima.Giuseppe
