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 l General purpose drill for steels, stainless steels, cast irons l High productivity drilling even on deep holes up to 7 x D l Twice the tool life of conventionally coated drills l Self centering l Surface finish and tolerances comparable to solid carbide l Regrindable extra long carbide head halves drill replacement costs Series Type Diameter Hole depthrange (mm)(L/D) Remark Short type (MAK Type) ø9,5~ø40,5 ~3 First choice general Long type (LAK Type) ø9,5~ø40,5 purpose drill~5 Extra long type (DAK Type) ø9,5~ø40,5 ~7 Helix angle:25° ---> 0° Series Performance l High efficiency drilling l Optimized drill geometry l Comparison of cutting power Comparison of coating damage Comparison of damage to drill margin (chip removal capability) when high speed drilling After 40 min. cut length KDS…AK TiAlN coated TiN coated KDS…AK Competitor’s drill KDS…AK type Chip stuck in flute vc = 120 m/min vc = 60 m/min After 30 m cut length (600 holes) Competitor’s drill Drill dia.: 18,0 mm Drill dia.: 18,0 mm vc = 50 m/min Drill dia.: 18,0 mm vc = 50 m/min Work material: C50 (HB230) f = 0,3 mm/rev Work material: C50 (HB230) f = 0,25 mm/rev Work material: C50 (HB230) f = 0,3 mm/rev doc = 50 mm doc = 38 mm doc = 90 mm (L/D=5) Application l Workpiece material l Automotive parts l Automotive parts examples - General steel and alloy steel Work material: C50 (HB250) Work material: 42CrMo4 (HB250) - Low carbon steel - Die steel KDS …AK KDS …AK - Stainless steel Concurrent A Competitor B - Ductile cast iron - Grey cast iron l l l l l l01002003000100200300 Tool life (Holes) Tool life (Holes) Drill: KDS 180 LAK (ø18,0mm) Drill: KDS 250 MAK (ø25,0mm) Conditions: vc = 55 m/min, f = 0,25 mm/rev Conditions: vc = 60 m/min, f = 0,25 mm/rev doc = 70 mm doc = 65 mm K47 (N)Cutting power Multi-Drills
