Review on 🔧 YIYATOO 3 175mm Carbide Engraving Router – Enhanced SEO-Friendly Product Name by Mario Bullard

I haven't used them yet, so I'm not ready to rate their cutting power, smoothness, or other "performance" characteristics . , we must try to figure out what's what. As in the photo, 2 containers of 10 bits each. Identical blue rubber caps on the tip. cases = good; identical color = not so good. Have you ever tried to visually guess the difference between 10 and 15 feet or even 20 and 30 feet? So maybe I can tell 10 feet from 30, but asking Yiyatoo to color the beats would be too much. Something like blue for 10 feet, yellow for 15 feet, red for 20 feet, and white for 30 feet. It took some time and fine-tuning of the caliper, but I was able to tell which bits were which. 10' and 30' were easy. 15' vs 20' is wrong, but I think I got it right. 10' was easy to identify but the profile was noticeably different. So 10 feet, +/- maybe 3 feet. 15' vs. 20' was also difficult because of the different profiles. I would estimate that the 15ft is actually 13-17 inches and the 20ft is actually 18-22 inches. So I think I'm right about something. But what I believe to be the 17 foot version of what should be 15 foot is really what it appears to be because I needed a strong magnification class to distinguish it from what I believe to be the 18 foot version of it distinguish which should be 20 feet. So the 3 stars come from (1) low price per hit; compared to (2) imprecise angles.
