| Reference values for determining cutting speed for W.Tec® insert coil thread former | |||
| Material | Strength | Cutting speed in m/min | Recommended lubrication |
| Structural steels, carbon steels, cold extrusion steels etc. | < 600 N/mm² | 20 - 80 | Cutting oil/emulsion |
| Structural steels, case-hardening steels, cast steel etc. | < 800 N/mm² | 20 - 60 | Cutting oil/emulsion |
| Heat-treated steels, cold working steels, nitriding steels etc. | < 1000 N/mm² | 10 -40 | Cutting oil |
| Stainless steel (austenitic, ferritic, martensitic) | < 950 N/mm² | 10 -25 | Cutting oil |
| Aluminium wrought alloys | < 550 N/mm² | 15 - 40 | Cutting oil/emulsion |
| Aluminium cast alloys | Si < 12 % | 15 - 40 | Cutting oil/emulsion |
| Pure copper | < 400 N/mm² | 20 - 40 | Cutting oil/emulsion |
| Brass (copper-zinc alloy) | < 550 N/mm² | 40 - 80 | Emulsion |
| Cutting speed [m/min] = (external diameter x π x speed)/1000 Speed n [rpm] = (cutting speed in m/min x 1000)/(external diameter x π) Feed [mm/min] = speed x thread pitch The cutting speeds indicated above are to be understood as reference values and may vary depending on the machining conditions and must be adjusted accordingly. | |||
