Furthermore, soft and hard materials are often combined in one workpiece. For example, wood with nails, plastic materials combined with inside steel frame (window frames), sheet material with PU / foam filling, etc. In this case you have to test and follow your 'feeling'. In the table below we give a rough guide to the recommended speed in common materials.
