MaxiMet end mills from Kennametal are what the company describes as the high productivity answer for aerospace and general engineering shops seeking to improve performance in machining high volumes of aluminum from parts.

The end mills are excellent wher both maximum metal removal rates and superior wall and floor finishes are required. One reason is the flute design that provides rigidity behind the cutting edges, enabling high feed rates. The results are more metal removed in fewer passes, lowering costs per part.

Additionally, a special edge condition and wiper facets on the MaxiMet corner geometry provide superior surface finishes. Available in two- and three-flute styles with choices of corner radii, the end mills can be used for roughing, semi-finishing, finishing, and super-finishing operations. The only limitations are the speed and horsepower of the machine tool and the balance of the setup. MaxiMet end mills also are excellent in thin-wall applications.

They are effective in slotting operations up to 1xD axially and side milling operations up to 0.5D radial and 1.5xD axial. Three-flute MaxiMets utilize HARVI unequal flute spacing to reduce harmonics in the cut. Less vibration and tool deflection allow higher metal removal rates and machining speeds.
