The KUB 100 indexable insert drill – a high-performance drill that delivers top-quality results in the machining of extremely diverse materials. When it comes to quality, handling, performance and reliability, the KUB 100 represents a milestone. This is due to the perfect combination of expertise in powder metallurgy and the latest coating technology

  • Just one indexable insert for both internal and external mounting
  • Indexable insert geometry with step for guided and controlled spot drilling
  • Optimum chip formation
  • PVD coating suitable for all materials – in particular steel and stainless steel
  • CVD coating for cast iron materials and high cutting speeds
  • Up to 30 % longer tool life compared to conventional indexable insert drills
  • Large, asymmetrically arranged chip flutes for optimum chip removal
  • Extremely rigid base body for low deflection and absorption of high transverse forces
  • Consistent deflection for virtually identical bore tolerances in all materials
  • Outstanding surface quality with no retraction scoring
  • Up to 20 % higher cutting and feed rate values, for extreme machining situations such as drilling through stacks, spot drilling on an edge, pointed corner or a weld joint or corrugated surface
