Turning insert with advanced PVD grade with hard AlTiN coating and fine grain unalloyed substrate. The new and improved coating improves edge stability with wide range speed and feed capabilities. The KCU25 grade is ideal for general machining of most steel, stainless steel, high temperature alloys, titanium, irons and non-ferrous materials in a wide range of speeds and feeds with improved edge toughness for interrupted cuts and high feed rates. Kenloc insert is the ﬁrst choice for general machining of all materials on medium to large lathes. Kenloc inserts offer the best economy for high metal removal rates. available in ﬂat top and chip control geometries with both moulded and ground peripheries. Suitable for all workpiece materials.
