APX Drill: High Rake (HR) Geometry   
  • Designed for materials with hardness < 200 BHN (700 N/mm2)
  • Improves chip formation in materials with very high elasticity/ductility, extremely poor chip forming characteristics, and low material hardness
  • Target materials: soft steels, steel castings and forgings (not suitable for stainless steels)
