Advanced Feed And Speed Calculator for Professional CNC Programmers and Machinists.


Here is a short Application Guide for use of different cutting tool materials and coatings.

Tool Materials and Coatings are listed from least preferable to most preferable.
(IE: line "Recommended tool materials: HSS, HSCobalt, Carbide, Diamond" means that HSS is the least preferable material and Diamond is the Most preferable one)

Tool Material

  • Aluminum and other non-ferrous metals:
    Recommended tool materials: HSS, HSCobalt, Carbide, Diamond
    Recommended number of flutes:2 or 3
    Recommended coolant: Flood Coolant for all tool materials, reduce cutting depth and speed for less than ideal cooling situations
  • Abrasive non-ferrous and non-metall materials:
    Recommended tool materials: HSS, HSCobalt, Carbide, Diamond
    Recommended number of flutes:2 or 3
    Recommended coolant: Flood Coolant for all tool materials, reduce cutting depth and speed for less than ideal cooling situations
  • Mild and Tool Steels
    Recommended tool materials:HSS, HSCobalt, Carbide
    Recommended number of flutes: 4 for regular machining; 4+ for finishing and HSM machining   
    Recommended coolant for HSS and HSCObalt tooling: Flood, reduce cutting depth and speed for less than ideal coolant situations
    Recommended coolant for Carbide tooling: Dry or mist airblast to clear the chips
  • Nikel and Cobalt Ferrous super alloys
    Recommended tool materials:HSCobalt, Carbide, Ceramics
    Recommended number of flutes: 3-4 for regular machining; 4+ for finishing and HSM machining   
    Recommended coolant for HSCobalt and Carbide: High pressure, high volume flood coolant
    Recommended coolant for Ceramics: None
  • Titanium alloys
    Recommended tool materials: HSCobalt, Carbide
    Recommended number of flutes: 3-4 for regular machining; 4+ for finishing and HSM machining   
    Recommended coolant: High pressure, high volume flood coolant

Tool Coating

Coating improves wear and temperature resistance of the cutting edge.
General rules of thumb:

  • Aluminum and other non-abrasive non-ferrous metals
    Recommended coatings:No Coating (bright finish), TiCN, ZrN, TiB
    Recommended coolant: Flood, reduce cutting depth and speed for less than ideal coolant situations
  • Abrasive non-ferrous and non-metall materials:
    Recommended coatings: TiAlN,AlTiN, AlCrN, Diamond
    Recommended coolant: Flood, reduce cutting depth and speed for less than ideal coolant situations
  • Mild and tool Steels
    Recommended coatings:TiN, TiCN, TiAlN, AlTiN, AlCrN
    Recommended coolant for HSS and HSCObalt tooling: Flood, reduce cutting depth and speed for less than ideal coolant situations
    Recommended coolant for Carbide tooling: Dry or mist airblast to clear the chips
  • Nikel and Cobalt Ferrous super alloys
    Recommended coatings:TiN, TiCN, TiAlN, AlTiN, AlCrN
    Recommended coolant: High pressure, high volume flood coolant
  • Titanium alloys
    Recommended coatings:No coating (bright finish); Super hard AlCrN, AlTiN, TiAlN nano coatings
    Recommended coolant: High pressure, high volume flood coolant
