How to drill a bearing
Hello everybody! I decided to show the test carbide drill, which can be purchased at about $ 1. In the people it is known as a "feather" (feather drill) and was originally intended for drilling tiles and tiles. In practice, it is already known that such a drill copes well with stone, concrete, glass. You can buy it on Ali for half a dollar and for less,Ali Express.After the drilling point is full, add oil and continue drilling. Now you can slightly increase the effort of pressure. In general, you need to do everything carefully and slowly.
Also copes well with high-alloy steel. For example, drill a 5-8 millimeter thick file with no problems with such a drill. I decided to give a harder task, drill a hole in a ball from a bearing 35 mm in diameter.First, start drilling without lubrication.The drill bit throws from side to side. Strongly you should not pressure.
