Fdrill Parameters£®2mm£©

Fdrill 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%
