Application Icon Explanation

• The icon indicates the application suitability for the grade. The icon is made up of a letter, a number, a face and droplet & sun.

   

  Letter

   

  The letter represents the suitable workpiece material.

  • P: Steel
  • M: Stainless Steel
  • K: Cast Iron
  • N: Non-ferrous Materials
  • S: Heat-resistant Super Alloys & Titanium
  • H: Hardened Steel

   

  Number

   

  The number coupled with letter gives the ISO grade.  Low numbers represent hard and wear resistant grades, while high numbers represent tough grades.

   

  Face

   

  The face represents the severity of the cutting conditions.

  • Happy face represents good conditions.
  • Neutral face represents average conditions.
  • Sad face represents bad conditions.

   

  Cutting conditions are dependent on the load (depth of cut, feed rate) and stability (degree of interruption, tool overhang).

  • Good Conditions range from average load & good stability or low load & average stability, to low load & good stability.​
  • Bad Conditions range from high load & average stability or average load & bad stability, to high load & bad stability.
  • Average Conditions range from high load & good stability or low load & bad stability, to average load & average stability.

   

  Droplet & Sun

   

  The droplet indicates that coolant should be used when cutting.

  The sun indicates that cutting should be dry.

  A droplet & sun indicates that 1^st choice is to cut with coolant, and 2^nd choice is to cut dry.

  A sun & droplet indicates that 1^st choice is to cut dry, and 2^nd choice is to cut with coolant.
