Parameters

Flowdrill Parameters:

Below you will find the parameters for all standard thread sizes, these parameters apply to mild steel 2mm. 

Spindle speed is our recommend level however a variation of 20% plus or minus can be used, this may result in a shorter tool lifetime. 

  • Stainless Steel reduce the RPM by 15%
  • Non-ferrous materials (copper, brass and aluminium) increace the RPM by 50%
