- 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
- Easy reference guide for insert number, screw, and other accessories is printed on the tool shank

- 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
