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

Works great. Accurate to about a third of a degree. Good enough for me. Helped me build a wooden box with six sides and no two angles the same. Good action on the tighten screw. Worth the money.

This is an excellent tool made by Shinwa. I'd asked some machinists and woodworkers and they recommended the Shinwa brand. So although paying a few dollars more for what looks to be such a basic tool, the quality of this stands out when compared to previous protractors which had would not hold their settings, or had markings that were hard to read.

[I revised my rating to 5 stars. I don't know why I was quibbling over a tiny error that's smaller than the width of the lines and on a par with normal random errors (like from tightening the locking screw). I'm leave the original review below, but now I think this is a 5-star product, especially for the price.] The build quality is good. The markings are nicely engraved. The hole in the arm is not perfectly centered (about .1mm off), leading the reading to be a little off. But I don't expect better than that. it's not that this protractor is made in China (guess where your phone came from). The reason is we paid $13.58 for it. The Starret C19 goes for $114.

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.

While a Japanese company, this tool was made in China. That said, it is a high quality item with a finely marked scale and well made pieces. Made of hard chrome stainless steel. Can recomend as a good value and I would buy it again.

This is a must have tool if you are sharpening bowl gouges for lathe work. Very simple to use and ensures that you are setting up your sharpening jigs ( eg. Wolverine/Vari-grind ) accurately and achieve the desired angle on your gouges.

Appears to be very well made, especially for the price! 90 degrees is dead-on with a small machinist angle I compared it against, and 0/180 degrees was dead-on against a flat surface. Clamp works great. Numbers & lines are very readable. Just no complaints, should work great for me!

This seems to be a fine instrument. I have used it a dozen times over the year since I bought it. It seems robust and accurate. My most common use is to align the tool holder on my lathe. The pictures show that the accuracy is very very good at 0 and 180 degrees. In both cases the edge of the reference bar is in perfect angular alignment with the edge of the disk. At zero degrees reference bar edge is actually in perfect coincidence with the edge of the protractor disk. The locking knob works smoothly and holds the angle firmly. There is no sign that the post is or will become loose. There is essentially no play between the reference bar and the post.

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

Einfach zu handhaben und hochpräzise. Essentiell in der Holzbearbeitung.

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

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