AVQNA4AGEHSS-CO AG 4 Flute End Mill 6496 4AGESold0pcsNACHI 6496 4AGE is the 4-flute standard option in the AG coated family. Four flutes mean more teeth and a stiffer core, so feed rates can be pushed in side and profile milling; switch to the 2-flute 6490 2AGE for slotting where chip evacuation matters. It is made from cobalt high speed steel (HSS-CO) with an AG (TiAlN-type) coating that resists heat and oxidation and allows dry or MQL cutting. Sizes cover diameter 2.5~50mm, flute length 7~70mm, overall length 50~160mm, shank diameter 6~42mm, 4 flutes, 64 in total, made in Japan. Diameters start at 2.5mm rather than 1mm because four flutes leave too little chip space at very small sizes. It suits carbon and alloy steel, stainless steel with workpiece hardness up to HRC35. Typical uses: side milling, profile finishing, and semi-finishing in steel and stainless. Can it slot? Four flutes leave little chip space, so use the 2-flute 6490 2AGE for slotting; this one covers diameter 2.5~50mm across 64 sizes.
