Very practical, well done
The external packaging was a plastic wrapper that arrived broken, fortunately, the five drill bits came in their plastic box, plus a sealed plastic bag. The drill bits have a poor quality appearance, bad paint, and poor finishes. I decided to try them immediately on a pine wood. I tested each of the drill bits and the result was terrible; first, none left a round hole, much less of the dimension of each drill bit. In fact, I compared the hole of the 20mm drill bit with one from another better quality brand and placed those 20mm metal stops used for workbenches, the result is that this stop was loose, it almost wobbled inside the hole. I measured the hole and the circumference was 21.2mm. None of the drill bits left the hole with the correct measurement, all were between 1 to 1.6mm wider, in addition to not having their correct circumference. I definitely do NOT recommend this product.
