5x Kennametal DFT 05T308-HP INSERT GRADE KCU40
DFT - HP Drill Fix DFT Inserts
High positive chipbreaker geometry preferred on ductile and normal chipping materials.
Insert Grade KCU40 (P25-P40)(M20-M35)(K15-K30)
Multilayered TiN-TiAlN-PVD coating and a tough substrate, that withstands interruptions and provides high wear resistance for long tool life. KCU40 is the first choice for high reliability in most materials. This grade should be used at medium speeds and high feeds due to sharper edges. KCU40 covers steel, stainless steel, cast iron, and high-temperature alloys for high toughness applications under certain conditions.
