CrazyDrill Crosspilot
perfect for holes on inclined surfaces

Shorter machining time

  • Savings of one tool: The three conventional operations of milling, centering, drilling are replaced by two - pilot drilling and drilling. CrazyDrill Crosspilot makes the pilot hole directly on inclined surfaces without pre-machining with an end mill. The deeper slanted drilling with a twist drill then follows after

Long tool life

  • High-performance coating ensures the best tool life
  • Sturdy design with reinforced shaft
  • Longer life for the follow-up drill since this is guided  in the pilot hole and there is no risk of breakage for the cutting edges

High process reliability -
high productivtiy

  • The CrazyDrill's high-performance geometry designed for extreme applications
  • Tungsten carbide drill with special tip geometry (170°) provides for good centering of the follow-up drilling and prevents breakage of cutting edges
  • Cylindrical guidance of the follow-up drilling prevents drifting
  • No jamming or catching of the follow-up drill due to diameter tolerances perfectly matched to all Mikron Tool deep-hole twist drill types such as CrazyDrill Cool and CrazyDrill Cool XL
  • No lateral catching due to a guiding chamfer

High degree of precision

  • High degree of position accuracy and straightness due to sturdy design
  • Highest degree of precision and straightness in deep holes longer than 6 x d since the pilot drill carries out cylindrical guidance, thus guiding the follow-up drill ideally.
  • No measurable transition from pilot drill to follow-up drilling

Lower production costs

  • Shorter machining time: two instead of three work steps
  • Savings of one tool (milling tool for creating flat surface )
  • Longer tool life and follow-up drill reliability because of adapted tolerances, tip angle and cylindrical guidance
  • CrazyDrill Crosspilot can be reground. With this tool costs are being reduced

Coordinated and complete drilling program

  • Pilot drill CrazyDrill Crosspilot with adapted diameter tolerance and tip angle for follow-up drilling using twist drill types such as CrazyDrill Cool and CrazyDrill Cool XL
  • Diameter/increments adapted to CrazyDrill twist drill types
    • Diameter range: drills 0.4 mm to 6 mm (.016” to .236”)
    • Diameter increments: up to diameters of 4 mm (.157”) every 0.05 mm (.002”), from diameter of 4 mm (.157”) and up every 0.1 mm (.004”)
  • Drilling depth: up to 2 x d (nominal)

Special characteristics

  • Savings of one tool = time savings
  • Direct drilling up to 60° (no DIN centering hole )
  • High degree of precision for the follow-up drilling, no deviation in deep holes
  • High degree of position and alignment accuracy
  • No measurable step between pilot drill and  long follow-up drilling
  • Tungsten carbide drill bit for steel and many other different materials (aluminum, titanium, cast iron, etc.) with very sturdy design that counteracts lateral forces
  • Very high process reliability since cutting edge angle breakout is avoided through adjustment of the tip angle from pilot to follow-up hole.
  • No lateral catching because a guiding chamfer is used
  • Can be reground and recoated; drilling performance of a re-sharpened CrazyDrill Crosspilot in terms of performance, precision and hole quality is equal to a new drill
  • 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)
