What speed should I run my Festool TS 55/65 on different materials and blades?

As the chart in user manual indicates, use the correct blade and these speed ranges for each type of material:
  • Solid wood (hard, soft) 6
  • Chipboard and hardboard 3–6
  • Laminated wood, blockboard, veneered and laminated panels 6
  • Laminate, mineral materials 4–6
  • Plaster- and cement-bonded chipboard, and fibreboard 1–3
  • Aluminium panels and profiles up to 15 mm 4–6
  • Plastics, fibre-reinforced plastics, paper and fabric 3–5
  • Acrylic glass 4–5.
