CrazyDrill Coolpilot Titanium ATC
Top drilling precision in titanium alloys

Maximum drilling speed

  • Pilot drilling and chamfering in one step (countersink drill bit)
  • Maximum machining speeds thanks to massive cooling of cutting edges
  • Drilling in one single step (no pecking)

Long tool life* – lasts up to 3 times longer

  • 4 times more cooling performance avoids overheating of the cutting edges
  • High-performance coating eXedur SNP protects the tungsten carbide drill from wear
  • Specially developed micro-grain solid carbide: high degree of fracture toughness and thermal shock resistance
  • The tool life span for the follow-up drill CrazyDrill Cool Titanium ATC is increased since it is guided in the pilot hole with a coordinated tip angle. This prevents the cutting edge from breaking

*Comparison based on drilling tools available on the market for pure titanium and titanium alloys and machining parameters recommended by manufacturers.

High process reliability

  • Helicoidal cooling channels with a new design:
    • Constant and substantial cooling of cutting edges, result: continuous and efficient chip removal
    • Up to four times the amount of coolant is delivered to the tip of the short drill
  • Perfect cutting ability and stability thanks to specific cutting-edge geometry
    • No tool jamming despite the viscoplastic properties of titanium
  • Cylindrical guidance of the follow-up drilling prevents drifting
  • Simultaneous chamfering with 90° angle replaces the countersink drill bit
  • No jamming of the follow-up drill CrazyDrill Cool Titanium ATC thanks to the perfectly matched diameter tolerances of both tools

High degree of precision

  • High degree of position accuracy and straightness thanks to its sturdy design
  • Double guiding margin ensures highest degree of straightness and surface quality
  • Most suitable drill bit for titanium alloys with good centering properties due to tip angle with small transverse cutting and chisel “s” shape
  • Highest degree of precision and straightness since the pilot drill creates a guide bore, thus guiding the follow-up drill
  • No measurable transition from pilot hole size to follow-up deep hole size

Lower production costs* 

  • Pilot drilling up to 3 x d and chamfer of 90° in one step and with one tool
  • Short machining time
  • Long tool life span due to heavy cooling
  • Long tool life span and reliability of the follow-up drill thanks to adapted tolerances

*Comparison based on drilling tools available on the market for pure titanium and titanium alloys and machining parameters recommended by manufacturers.

Coordinated and complete drilling program

  • Pilot drill CrazyDrill Coolpilot Titanium ATC with adapted diameter tolerance for follow-up drilling using twist drill types such as CrazyDrill Cool Titanium ATC
  • Diameter range: Drills 1.0 mm – 6.35 mm (.039” – .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”)
  • Drilling depth: up to 3 x d

Special characteristics

  • Pilot drilling and chamfering (90°) with one tool possible
  • Pilot drill with through-tool coolant: new concept of helicoidal internal coolant channels (droplet shaped) supply up to 4 times more coolant flow. This guarantees optimal cooling and chip evacuation
  • Double guiding margin ensures highest degree of straightness, roundness, and surface quality
  • Sturdy tungsten carbide shank guarantees stability, high concentricity and therefore the highest degree of drilling precision 
  • 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
  • Guaranteed high degree of precision for follow-up drilling, and no deviation in deep holes
  • Diameter measurements, increments and tolerances matched to CrazyDrill Cool Titanium, therefore higher tool life span for the follow-up drill
  • Can be reground and recoated from 1.4 mm (.055”): drilling performance of a re-sharpened CrazyDrill Coolpilot Titanium in terms of performance, precision, and hole quality is equal to 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)
