Shars 4" 90° Coolant Thru Heavy Duty Face Mill LNKT 160708 Insert 404-7956 S[

LNKT insert with 4 cutting edges suitable for milling in steel, stainless steel, cast iron and other difficult machined materials. Vertical mounting of the insert changes the direction of cutting forces which is absorbed by the thick carbide insert body to increase tool rigidity. Vertical mounting design combined with thick carbide insert increases the potential feed rate by 30% in roughing compared to horizontal mounted insert such as APKT. Low runout of the square shoulder leaves good surface quality in workpiece and no obvious tool marks in the contours. Double positive rake angle design reduces cutting forces. High strength tool body material with coolant thru port on each flute. High strength positive cutting edge angle for increased wear resistance and reduced cutting pressures. Helical cutting edge is designed to achieve smoother cutting. Highly versatile and ultra smooth coating technology prevents chip welding for longer tool life. YB9320 grade combines substrate with good toughness and strength and TiAlN nano PVD coating process to yield high strength and toughness. Widely applicable for semi-finish milling of P type (P10-P30) and M type (M10-M30) material.
