Review on 🔧 Yakamoz 1 15mm Stainless Welding Metric Kit by Chris Chincuanco

The instructions say it's good to check the wrong hole. If you don't sharpen the edges it will work for the hole as the integer is the radius and the edge of that rectangle won't match. I am a machinist with 30 years of experience. This is easily remedied by sharpening the edges to a point. If you want to use it to measure the distance between two flat planes then it's great. If you know these details, it's worth the money.
