Important: Also check if the materials are already hardened, usually you know the material and the size of the drill. Now you have to find out which speed to set on the drill. The mathematicians among you can calculate this with a formula . The formula for the cutting speed (m/min) is

The cutting speed is given in meters per minute (m/min). It depends on the material (e.g. mild steel) being machined, the material of the cutting tool (HSS or HM) and the type of process (drilling/wheeling/tapping).

The correct cutting speed is important to achieve good work results and minimize tool wear. The best way to understand the cutting speed is to draw a large circle on a sheet of paper. Now move your index finger along the line of the circle. You are now travelling a certain distance in a certain time. This is the cutting speed. It is determined by the diameter of the drill and the speed of the drill. Certain materials require certain cutting speeds. The cutting data is determined by the manufacturers of the tools. Let’s take a look at them:
