Faqs:
  • What materials can this drill handle?
    It is suitable for aluminum alloys, cast iron, compacted graphite iron (CGI), and steel engine blocks.
  • Why is the TiAlN coating beneficial?
    TiAlN provides excellent thermal stability and reduces friction, extending tool life during high-speed and dry or MQL machining.
  • What coolant systems can be used?
    Compatible with water-soluble coolant, cutting oils, and MQL systems, with high-pressure through-coolant capabilities.
  • What is the recommended cutting speed?
    Typical speeds are 60-150 m/min for cast iron and 150-300 m/min for aluminum alloys, depending on the coolant system and machine rigidity.
