Review on 🔧 Yakamoz 1 15mm Stainless Welding Metric Kit by George Kapoor

Taper gauges are inherently inaccurate due to their thickness when measuring a hole rather than a parallel slot. Holes on this thicker gauge. The actual opening of 4.82mm is measured on this gauge as 4.4mm on its scale due to the thickness of the cone reducing the measured diameter. Most reputable companies will provide you with a correction scale so you can roughly adjust the reading for a more accurate estimate of hole size. I like the dual scale on one gauge, both scales are fairly accurate when checked with a good quality Mitutoyo digital caliper.
