  2. Cooling management :
    • After 20 minutes of operation, cool down in water for 2 minutes → +40% lifetime

  3. Pressure control :
    • Max. 5kg pressure force for smooth cutting edges


🌟 Main advantages at a glance

Lightning-fast drilling performance : 1 cm in 10-15 seconds (porcelain stoneware)
