MaxiMet end mills, new from Kennametal, are designed for aerospace and general engineering shops seeking to improve performance in machining high volumes of aluminum parts.One reason for this performance is the tools? flute designs that result in high rigidity behind the cutting edges...
Three-flute MaxiMets are designed with HARVI unequal flute spacing to reduce harmonics in the cut, resulting in less vibration and tool deflection for high metal-removal rates and machining speeds. ================================================================
