Brazed Carbide MULTI-DRILLs KDS Type Description The new AK type drill features an extra long carbide drill head, new cutting geometry, coolant holes and ultra hard TiAlN coating for reliable high productivity drilling. Advantages General purpose drill for steels, stainless steels, cast irons High productivity drilling even on deep holes up to 7 x D Twice the tool life of conventionally coated drills Self centering Surface finish and tolerances comparable to solid carbide Regrindable extra long carbide head halves drill replacement costs Series Type Diameter range (mm) Hole depth (L/D) Remark Short type (MAK Type) 09,5 040,5 3 First choice general purpose drill Long type (LAK Type) 09,5 040,5 5 Extra long type (DAK Type) 09,5 040,5 7 Helix angle: 25° -> 0° Series Performance High efficiency drilling Comparison of coating damage when high speed drilling TiAlN coated KDS...AK TiN coated type vc = 120 m/min vc = 60 m/min After 30 m cut length (600 holes) Optimized drill geometry Comparison of damage to drill margin After 40 min. cut length KDS.
