EN 10025-5 1.8961 Material Machining Technology
Drilling is a simple machining process used to create holes in metal. It involves using a sharp drill bit that is rotated by a motor. The drill bit is pressed against the material, which is cooled and lubricated, as it cuts away material to create a hole. When working with EN 10025-5 1.8961 steel, conventional drill bits can be used.
