CrazyDrill / CrazyMill Hexalobe
Saving time while increasing 
precision and quality

• Drilling and chamfering in one step (save one operation for chamfering)
• Short cycle time for milling thanks to high removal rate (ap and ae), i.e. high-angle milling with helical interpolation

For example: milling in Titanium, version 3.5 x d, p = 0.4 x d (quality and cycle time depending on cutting parameter and machine conditions)

*Comparison based on drilling/milling tools available in the market for stainless steel and titanium and machining parameters recommended by manufacturers.

• High degree of precision of profiles
  • Thanks to robust carbide shank
  • Thanks to new carbide with edge chipping resistance

• Very accurate perpendicularity
  • Thanks to high stiffness of the tool        

• High quality of chamfer surface (lowest roughness)

• Excellent surface quality of hex lobular socket
  • Thanks to axial removal rate and vibration free milling (robust carbide shank)

• Machining profile with minimal burrs - nearly burr free

• Up to 3 times longer tool life*
  • Thanks to good chip breaking when drilling  
  • Thanks to new heat- and wear-resistant coating  

*Comparison based on drilling/milling tools available in the market for stainless steel and titanium and machining parameters recommended by manufacturers.

• Thanks to faster machining
• Thanks to longer tool life
• Thanks to combined drill: one single tool for pre-hole drilling, chamfering and deburring

  • New carbide: special micro-grain carbide with high stiffness and edge chipping resistance, developed for high profile precision
  • Chrome free coating to avoid a cross contamination on medical parts

• New concept: drilling – chamfering – milling – deburring: four operations in three steps with two tools
• Highest efficiency and short machining time for Titanium, Stainless Steel and Cobalt Chrome
• Three specific geometries for the machining of Titanium, Stainless Steel and Cobalt Chrome: CrazyDrill Hexalobe Flat - one geometry; CrazyDrill Hexalobe - two geometries; CrazyMill Hexalobe - three geometries
• High-performance coating eXedur SNP, chrome free, heat and wear resistant prevent buildup of edges and guarantees optimum chip flushing 
• Micro-grain carbide with high stiffness and edge chipping resistance
• Highest surface quality and profile matching
• Mikron Tool produces all tools with highest repeat precision. Hence the user will benefit from long term stable production conditions (stable process and machining precision)
