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

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

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 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

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

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 6.35 mm (.016” to .250”, fractional inches available)
- 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)

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)
