CrazyMill Cool Ball Z4
Tungsten carbide finishing cutter
with through-tool cooling
from 1 mm (.039”)

• Extremely high metal removal rates (Q) thanks to
  • High tool performance (ap up to 4 x d)
  • High cutting speeds (vc up to 280 m/min (919 SFM))
• Clearly improved efficiency over commercially available tools

*The comparison takes into consideration the milling tools and milling methods available on the market as well as the machining parameters recommended by manufacturers.

• Through-tool cooling with extremely efficient and high volume flow of cooling lubricant due to large cooling channels compared to the milling tool’s diameter. Thanks to the continuous cooling with oil or emulsion, no friction heat is generated during the milling operation
  • No overheating of cutting edges
  • Chips are flushed away
• High-performance coating eXedur SNP:
  • High-temperature and oxidation-resistant
  • High degree of wear resistance
  • Low adhesion to metals prevents bonding
  • No deposition of chips due to low friction coefficient
• The life of the CrazyMill Cool Ball Z4 is up to five times longer in comparison to commercially available milling tools

*The comparison takes into consideration the milling tools and milling methods available on the market as well as the machining parameters recommended by manufacturers.

• Controlled temperature during the whole milling process due to through-tool cooling
  • No overheating of cutting edges
  • No overheating of the high-performance coating
  • No material buildup on cutting edges, the cooling does not allow heat to build up on the cutting edges
• High stability on the transition from the radius to the cylindrical section; the risk of cutting edge break-out is reduced

*The comparison takes into consideration the milling tools and milling methods available on the market as well as the machining parameters recommended by manufacturers.

• Special geometry for smooth milling without vibrations
• Targeted flushing of the chips by means of through-shaft cooling
• Milling at the radius and cylindrical section: few mill paths for finishing
• Versions with long cutting lengths for side finishing in one mill path
• Surface quality with values in the range of Fine-Grinding or even Ultra Fine-Grinding

• Shorter machining time: up to 5 times faster
• Excellent tool life: up to 5 times longer

*The comparison takes into consideration the milling tools and milling methods available on the market as well as the machining parameters recommended by manufacturers.

• Ball mill with four teeth for copy and side milling, applied for semi-finishing and finishing; standard milling sizes 1.0 mm – 8.0 mm (.039” - .315”, fractional inches available)
• Versions with cutting length 2 x d:
  • Type A (max. milling depth 2 x d)
  • Type B (max. milling depth 3 x d)
  • Type C (max. milling depth 5 x d)
• Versions with progressive flute-angle:
  • Type M (max. milling depth 3.5 x d) with cutting length 3.5 x d
  • Type N (max. milling depth 4.5 x d) with cutting length 4.5 x d
• Milling tools with 4 mm (.157”), 6 mm (.236”), 8 mm (.315”), 10 mm (.394”) and 12 mm (.472”) shaft

• Unique and patented - new horizons in milling
• HSPC (high-speed performance cutting) in all metals (such as all unhardened steel grades, aluminum, nonferrous metals), especially suitable for difficult-to-machine materials (such as stainless and acid- and heat-resistant steels, titanium and super alloys)
• Through-shaft cooling channels: regular and substantial cooling and targeted flushing of chips
• Wear-resistant and heat-resistant high-performance coating eXedur SNP (this coating is especially suitable for finishing operations)
• Tungsten carbide with high fracture toughness and thermal shock resistance
• Two versions with especially long cutting edges: a progressive flute-angle (from 30° into 40°) guarantees vibration less milling and thus improves once more the surface quality; especially suitable for side milling because in one mill path the entire depth can be machined
• Surface factor 2 - 4 times better than the competition
• High chip removal rate (3 up to 8 times greater, depending on the machined material)
• Longer tool life: up to 5 times longer in comparison to all other commercially available products
• 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)
