Hello. Sharpening drills is a topic of videos that you liked on my RU-vid channel, which I am very happy about. You also come back to these films often. This time we will try to approach the topic in a professional way, i.e. we will use a special sharpener for MR-13B Vevor drills s.vevor.com/bfQM02 - we will perform various tests and check how this equipment will cope and whether it is worth having it in your workshop. We will also cover the basic knowledge of the construction of drills, I will also tell you what to pay attention to when sharpening and what to do to avoid damaging the drills.
