CrazyMill Cool Square/
Corner radius end mill Z4 –
Pre-machining and finishing 
from 1 mm (.039“)

• Thanks to high tool performance (ap up to 1 x d) and high cutting speeds (vc up to 350 m/min (1148 SFM)) extremely high removal rates (Q)
• 2 times higher efficiency than with other commercially available tools
• Milling with helical interpolation or linear ramp with steep ramp angles (up to 45° depending on material) thanks to specially designed, expanded chip collection in the end section

*: 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 prevents overheating of cutting edges and guarantees best chip evacuation
• Large cooling channels compared to the milling tool’s diameter:
  • Extremely efficient and high-volume flow of cooling lubricant removes chips from machining area: no cutting-edge break outs.
  • The friction-generated heat is mostly absorbed and absorbed by the cutting oil: no material buildup on the cutting edges
• 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 tool life of CrazyMill Cool Z4 is up to four times longer compared to other 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.

• No overheating of cutting edges or of the tungsten carbide due to through-tool cooling
• No overheating of the high-performance coating due to efficient and high volume cooling
• Through-tool cooling prevents material buildup on cutting edges and does not allow heat to build up on the cutting edges

• Perfect surface finish quality thanks to targeted flushing of the chips by means of through-shaft cooling

Material: X2CrNiMo17-12-2 / 1.4404 / AISI 316L

Diameter: 8 mm (.315“)
Milling depth: 16 mm (.630“)
Cooling lubricant: cutting oil
Cutting data: vc = 260 m/min (853 SFM), ap = 16 mm (.630“), ae = 0.16 mm (.006“)

• Perfect chip control due to optimized chip-breaking: short chips and highest surface quality. No visible marks, as it can happen when using conventional milling tools

• Excellent perpendicularity due to flute profile and core size → greater stability

• Cylindrical (protection phase of 45°) and toric (corner radius) micromill with four flutes and through-tool cooling
• Diameter range 1.0 mm – 8.0 mm (.039” – .315”, fractional inches available)
• For each type four versions:
  • Type A (max. milling depth 2 x d) with cutting length 2 x d
  • Type C (max. milling depth 5 x d) with cutting length 2 x d
  • Type M (max. milling depth 3 x d) with cutting length 3 x d
  • Type N (max. milling depth 4 x d) with cutting length 4 x d
• Milling cutters with 4 mm (.158”) shaft / 6 mm (.236“) shaft / 8 mm (.315“) shaft / 10 mm (.394“) shaft / 12 mm (.472“) shaft

• Through-shaft cooling channels: regular and substantial cooling and targeted flushing of chips
• Unique and patented 
• "HSPC" (HighSpeedPerformanceCutting), especially suitable for difficult-to-machine materials (such as stainless steel, titanium alloys, CrCo and superalloys)
• Cutting geometry of end face for perfect milling with linear ramp or helical interpolation with steep ramp angles due to specially designed expanded chip collection 
• High tool rigidity: higher machining force resistance thanks to robust lateral cutting edges specially for the long versions M and N → high degree of precision (perpendicularity) and excellent surface quality
• Optimized chip-breaking of the long versions M and N guarantees short chips and hence highest surface quality
• Suitable for milling of sides and pockets
• Pre-machining and finishing with one tool
• Tungsten carbide with high fracture toughness and thermal shock resistance  
• Wear- and heat-resistant high-performance coating eXedur SNP
• 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)
