CrazyDrill Cool XL
extra long drill with through-tool
cooling for deep holes
Short machining time
- Maximum feed rate, therefore perfect alternative to gundrill
- One step = one deep hole
- No deep-drilling cycle with chip break and chip removal needed
- Good chip removal because of improved flute geometry and surface
Excellent tool life
- Thanks to specific cutting-edge treatment before coating and subsequent polishing of drill flutes and tips
- Tungsten carbide drill for steel with high-performance coating: lower friction coefficient guarantees less heat buildup, protects from cutting edge breakage and wear; low adhesion to material prevents bonding; resistant to thermal loads (high hot hardness)
- Two internal cooling channels provide for optimal cooling at the tip
- Power chamber in the shaft up to drill bit size diameter of 3 mm (.118”):
- Sufficiently large coolant flow even at lower pressure
- Greater coolant flow at identical pressure
High degree of process reliability
- Produces short chips thanks to especially developed chip flute geometry (no drill breakage due to coiling of chips)
- Clearly defined drilling process
- Adapted program (tip angle and diameter tolerances) with the pilot drill CrazyDrill Pilot or when drilling on inclined surfaces with CrazyDrill Crosspilot
- Good chip removal thanks to drill geometry and through-tool cooling
Highest precision
- High degree of diameter accuracy and surface quality
- Very high degree of perpendicularity and roundness thanks to a double margin
- Highest degree of alignment accuracy
Economical drill
- Quick drilling process
- Long tool life
- High degree of process reliability
- The micro deep-hole drill can be reground and recoated. With this tool costs are being reduced
- Can replace cost intensive deep-hole drilling with single lip drills (gundrill) (50% to 95% shorter machining time)
Coordinated and complete drilling program
- CrazyDrill Pilot: Mikron Tool recommends the use of the piloting/centering tool CrazyDrill Pilot as perfect hole preparation for high-precision position accuracy in deep-hole drilling (no deviation)
- 15 x d / 20 x d / 30 x d: drill size diameter range 1 mm – 6 mm (.039” – .236”, fractional inches available)
- 40 x d: from drill size diameter 2 – 6 mm (.078” – .236”, fractional inches available)
- Increments:
- Every 0.05* mm (.002“) up to Ø 4 mm (.157“)
- Every 0.10 mm (.004“) from Ø 4 – 6 mm (.157“ – .236“)
- *Increments 0.05 mm (.002“) from 20 x d: delivery term upon request
- Twist drill angle on the drill tip 140°, same as CrazyDrill Pilot
Special characteristics
- Sturdy drill with through-tool cooling for deep-hole drilling
- Carbide drill for steel (alloyed and not alloyed, stainless), cast iron, aluminum and titanium
- Latest-generation solid carbide
- Special high-performance coating eXedur SL
- Specific cutting-edge treatment
- Diameter tolerances of pilot drill and drill are matched. Consequently, there is no measurable transition from pilot drilling to follow-up drilling, nonetheless reliable drilling without drill jamming
- Can be reground and recoated; drilling performance of a re-sharpened CrazyDrill Cool XL is equal to that of 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).
