ARNO-Werkzeuge Karl-Heinz Arnold GmbH

Short hole drill for performance drilling

• Coolant through
• Use 4 edges per insert for reduced costs per hole
• High process reliability even for interrupted cuts
• Drilling into concave shapes, stacked work pieces and packet drilling
• High process security due to very strong inserts
• High productivity due to high feed rate potential
• Nickel plated and polished surface for better swarf evacuation
• Improved run-out into the location flat

Grades

• AP5030 PVD-Multilayer coating, Substrate + TiAlN
  A tough universal grade in the P30 – P35 ISO range. Main application area is drilling steel but also suitable for stainless steel. Can also be used for interrupted cuts.
  
• AK5020 PVD-Multilayer coating, Substrate + TiAlN
  Main grade for drilling cast materials. Extreme performance due to combination of fine grain substrate and coating. For use with medium cutting speeds under normal to stable machine conditions.
  
• AK1010 (uncoated)
  The main grade for drilling GG cast iron, aluminum, aluminum alloys, copper and copper alloys as well as bronze and brass at medium speeds and in good machine conditions.
