CrazyDrill Coolpilot Titanium ATC
Top drilling precision in titanium alloys

• 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)

• 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.

• 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 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

• 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.

• 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

• 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)
