CrazyDrill Alu
repeat accuracy and productivity

Short machining time

The machining time of the work-piece decreases significantly because of highest drilling speed and minimum chip removal
Self-centering due to the three flutes geometry; no centering needed

Highest degree of drilling precision (position accuracy), self-centering due to three flutes
A high degree of hole roundness due to a sturdy standard shaft which ensures a high degree of concentricity accuracy
High degree of alignment accuracy
Excellent surface quality
Minor burr formation due to 130° tip angle and sharp drill tip geometry

Drill bit diameter range 0.4 mm – 3 mm (.016” to .118”), increments every 0.05 mm (.002”)
Drilling depths up to 5 x d and up to 10 x d
The CrazyMill Chamfer family is best suited for deburring or chamfering aluminum
In deeper holes (beyond 10 x d) or holes with a diameter greater than 3 mm (.118”), Mikron Tool recommends drills with through-tool cooling such as CrazyDrill Cool and CrazyDrill Cool XL

Highest drilling speed
Highest degree of drilling precision and excellent surface quality
Self-centering due to the three flutes geometry, no prior centering or pilot drilling needed
Minimum chip removal (beyond 5 x d) due to special helical groove geometry
Extraordinary tool life of the drill for aluminum
Suitable for all aluminum alloys
High degree of productivity because of high feed rates
Mikron Tool recommends cutting oil as cooling lubricant; alternatively, water based coolant with EP additives can also be used, or minimum-quantity lubrication is also possible in case of reduced cutting data
Can be reground and recoated; drilling performance of a re-sharpened CrazyDrill Alu is equal to a new drill in terms of performance, precision and hole quality
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)
