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
Longer tool life
- Drill for aluminum with long tool life
- Special DLC (diamond-like carbon) coating offers protection against wear
High process reliability -
high productivtiy
- Self-centering due to three flutes design
- Drill cuts very well because of sharp drill point geometry
- Optimal chip flow through smooth DLC coating (chips do not adhere to drill)
- Only minimum chip removal (pecks) needed due to special helical groove geometry
- Clearly defined drilling process
High degree of precision
- 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
Low production costs
- Extraordinary tool life
- Highest degree of productivity, reliability and repeat accuracy
- Minimum chip removal (pecks) (beyond 5 x d)
- No pilot drilling or centering needed
- CrazyDrill Alu can be reground. With this tool costs are being reduced
Complete drilling program for this drill for aluminum
- 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
Special characteristics
- 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)
