Our new grade for applications in though materials.
X-treme tough for wide range applications in Drilling Milling.
K40XF is designed for broad band application and is especially suited for machining tough work piece materials in the hardness range < 45 HRC. Including stainless steels, Carbon steels as well as Titanium and Nickel alloys. K40XF works well at low cutting speeds, high feed rates and interrupted cutting.
K40XF was exclusively developed with respect to a significantly improved toughness. Combination of 0,8 µm WC grain size and 10 percent Cobalt yields to a high toughness, with simultaneous adequate hardness.
