Hello everyone FRIENDS! You are watching the channel Cheerful engineer.
Today, the vertical drill will be in our video tutorial, namely the vertical drill on metal. This tool is quite popular and deserves our attention. If you want to see the dimensions of this tool, namely the Zenker GOST to help you. If you need to improve the hole according to your process technology, then this is a surface drill. The design of the core drill differs from the drill in its very small design features. When I first saw the vertical drill, the drawing didn’t impress me, but I noted for myself that it looked very much like a drill. A very important question is the countersink and the countersink, namely how they differ. The hole countersink is machined using practically the same cutting conditions. There is such a thing as a vertical drill under a drill, it means that under a certain drill there is a GOST standard drill. In my video you will see a countersink photo of his work and much more. If we talk about the design, the parts of the countersink are very similar to their fellow drill. And the elements of the core drill differ from the drill only in the cutting part and the screw of the chip discharge grooves. I will answer in this video the main question of my subscribers, countersink and countersink difference. Well, what can I say about a countersink tool that significantly improves the cleanliness class and reduces roughness. Such a cutting tool as a countersink should be in every production and enterprise of our vast homeland.
