CrazyDrill Cool Titanium
high-performance drilling in titanium

• High cutting speeds thanks to continuously high and massive cooling of cutting edges
• High efficiency compared to other commercially available tools

• 4 times more cooling performance avoids overheating of the cutting edges and ensures that the chips are flushed away
• High-performance coating eXedur SNP:
  • High-temperature and oxidation-resistant
  • High degree of wear resistance
  • Low adhesion to metals to prevent bonding
  • No deposition of chips thanks to low friction coefficient
• The CrazyDrill Cool Titanium tool lasts up to three times longer compared to other commercially available drilling tools

*The comparison considers the drilling tools available for pure titanium, titanium alloys, and the machining parameters recommended by manufacturers.

• New concept of helicoidal internal coolant channels:
  • Up to four times more coolant volume reaches the drill tip
  • The result is continuous and efficient chip removal as well as constant and substantial cooling of cutting edges
• Unique cutting-edge geometry with optimum cutting ability and stability
  • No tool jamming despite the viscoplastic properties of titanium, even at increasing drilling depths
• Defined and certified drilling process with specifications for cutting speed and feed rate

• Sturdy tungsten carbide shank supports stable and vibration-free drilling
• Double guiding margin ensures highest degree of straightness and surface quality
• Most suitable drill bit for titanium with good centering properties due to tip angle with small transverse cutting and chisel “s” shape
• High degree of positional and drilling accuracy (diameter tolerance): diameter precision of the drill k5 +0 mm / + 0.004 mm (.0” /+ .00016”) ≤ Ø 3 mm; +0.001 mm / + 0.006 mm (.00004” /+ .00024”) > Ø 3 mm up to ≤ 6.35 mm
• Good alignment accuracy (no deviation) and hole roundness
• For drilling depths over 6 x d: high position accuracy due to pilot drilling with pilot drill CrazyDrill Coolpilot Titanium ATC

• Maximum drilling speed (e.g. 10 x d in one step with ATC)
• Longer tool life: lasts up to 3 times longer
• Higher process reliability

*The comparison considers the drilling tools available for pure titanium, titanium alloys, and the machining parameters recommended by manufacturers.

• Pilot drilling / centering:
  For drilling depths up to 6 x d, centering is not necessary on straight surfaces. With its tip angle of 139° and its chisel “s” shape, the drill has good self-centering. However, we recommend pilot drilling or centering only on irregular, rough (with CrazyDrill Coolpilot Titanium ATC) or incline surfaces (with CrazyDrill Crosspilot) and if a high degree of position accuracy is required.
  For drilling depths over 6 x d, Mikron Tool recommends pilot drilling with CrazyDrill Coolpilot Titanium ATC or CrazyDrill Crosspilot on inclined surfaces.
• ​​​​Diameter range: Drills 1 mm – 6.35 mm (.039” to .250”, fractional inches available)
• Diameter increments: up to 4 mm (.157”) every 0.05 mm (.002”), 4 to 6 mm (.157” to .236”) and up every 0.1 mm (.0039”)
• CrazyDrill Cool Titanium ATC with usable length of 6 x d, 10 x d
• CrazyDrill Cool Titanium PTC with usable length of 3 x d, 6 x d

• New concept of helicoidal internal coolant channels (droplet shape) supply up to 4 times more coolant flow, to guarantee optimal cooling and chip evacuation
• Titanium drills with two specific geometries: PTC for pure titanium grades and ATC for titanium alloys
• Innovative flute and tip geometry
• Sturdy tungsten carbide shaft, to guarantee stability and a high degree of concentricity 
• Specially developed micro-grain solid carbide with high degree of fracture toughness makes drilling possible at high cutting speeds
• Wear- and heat-resistant high-performance coating eXedur SNP
• PTC version with chip barrier margins
• Self-centering with drilling depths up to 6 x d
• Longer lasting tool life (up to 3 times longer)
• Maximum drilling speed (e.g. 10 x d in one step with ATC)
• Very good drilling precision (roundness, straightness, diameter precision)
• Can be reground and recoated from 1.4 mm (.055”): drilling performance of a re-sharpened CrazyDrill Cool Titanium in terms of performance, precision and hole quality is the same as using a new drill
• Mikron Tool produces all tools with the highest repeat precision. This means that users will benefit from long-term stable production conditions (stable process and machining precision)
