Internally and externally conical flights
Flights, which are internally and externally conical, are difficult to produce. Often it is necessary to produce several samples before all the measurements are correct. Test mandrels are often produced in order to verify measurements. Consequently, this type of flights is more expensive than flights, which are either internally or externally conical.
- Lead time for double conical flights is 1-2 weeks.
