ARNO-Werkzeuge Karl-Heinz Arnold GmbH

Flexible drilling system with replaceable carbide inserts

General information

• Flexible system: one holder for different drill diameters
• Robust and secure insert clamping with TORX-Plus® screws
• Optimized coolant through for all holders
• Optimized run-out of swarf chambers reduce drill overhang
• Widened swarf chambers for higher chip loads
• Improved drill point design for excellent centering hole quality
• Strong shank design for high axial forces
• Quick and easy insert replacement even in the machine
• Easy identification thanks to lasered spare part numbers on tool shank
• Carbide drilling insert: Coated and un-coated Ø 14 mm – 32 mm

Grades Carbide coated

• AP5440
  PVD coated carbide grade
  First choice for steel drilling, also suitable for stainless steel.
  
• AP5025
  PVD-Multilayer coating, fine grain carbide
  Main application is machining steel. Also suitable for stainless steel and cast materials. Very universal grade with high temperature and oxygenation resistance.
  
• AK5015
  The hard substrate is especially suitable for cast materials also hard cast and unusual drill depths. The grade is very wear resistant as well as resistant to build up edge. 
  
• AM5040
  The grade for drilling stainless steel, soft cutting and with good swarf control. The high toughness ensures low wear. Machines well at varied cutting depths and interrupted cutting.
  Carbide uncoated
  
• AK1025
  Fine grain carbide, uncoated
  For machining aluminum and non-ferrous materials. Excellent as base grade for customer specific coating solutions.
