                    • KC7140

                      Composition: PVD TiCN/TiN coated medium-grain carbide with high toughness.

                      Application: Best suited for machining of steel and stainless steel. This exceptionally tough grade is perfectly suited for metastable machining conditions offering excellent tool life.

                      Multi-Layered Tin-TiCN-TiN MT-CVD coating over a tough substrate
                      For low carbon steel
                      Superior performance when drilling low-carbon steels and cast iron at elevated speeds
                      Available in DFR-style inserts with -MD geometry for enhanced chip control
                      In DRILL-FIX bodies, use grade KC7140 in the inboard pocket, KC7820 in the outboard pocket

                    • KCU25

                      Turning Composition: An 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.

                      Turning Application: The KCU25 grade is ideal for general machining of most steels, stainless steels, high-temp alloys, titanium, irons, and non-ferrous materials in a wide range of speeds and feeds with improved edge toughness for interrupted cut and high feed rates.

                      Holemaking Composition: Advanced CVD TiCN-Al2O3 coating combined with a tough carbide substrate.

                      Holemaking Application: First choice for steel, stainless steel, and cast iron. This grade offers adequate deformation resistance, excellent edge strength, and superior wear resistance over a wide range of machining conditions for high productivity with very good reliability.

                      K Cast Iron
                    • KCU40

                      Composition: Multilayered TiN-TiAlN-PVD coating and a tough substrate, that withstands interruptions and provides high wear resistance for long tool life.
                      Application: 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.
