The Z-Carb HPR Five Flute Roughing End Mills are ideal for achieving high metal removal rates (MRR) and a finish of 80 RMS or better on most materials. The specialized five flute design is engineered for increased productivity over three and four flute end mills. The variable indexing geometry allows for improved chatter suppression over symmetrical designs.

Features

Radial Rake

Graphic demonstrating positive rake
  • Specially designed radial rake balances positive cutting action and edge strength.
  • End grind features include a positive axial rake for high-performance shearing and lifting of material and increased clearances to eliminate edge build-up during ramping.
Through Coolant Options

  • The central hole delivers coolant effectively to the cutting zone.
  • Enhances chip removal when pocketing or slotting.
  • Select fractional and metric diameters in stock.
Fluting & Helix Angle
End mill and drill flutes
  • Specialized five-flute design is engineered for strength, chip evacuation, and increased productivity over three and four-flute end mills by 20–40%.
  • The variable flute pattern provides excellent chatter suppression over a range of spindle speeds.
  • The open-center design delivers efficiency during entry movements into the workpiece.
  • Helix angle engineered for balance between positive cutting action and reduced contact area to control tool pressure and spindle load.
Coatings
Ti-namite-m coating logo

Ti-NAMITE-M - Higher heat resistance to enhance tool life in difficult-to-machine materials like Titanium

Ti-namite-a coating logo

Ti-NAMITE-A - Superior wear, edge build-up resistance and extended tool life in difficult-to-machine materials like Stainless Steel

Ti-namite-a coating logo

NEW MEGACOAT NANO - Nano-layers of this coating provide high hardness for exceptional wear resistance and high oxidation resistance that allows for operation at high temperatures. The layered structure also gives the coating the toughness required to resist chipping.
