3 TurnLine New positive geometry inserts with innovative coating technology deliver highly stable machining of heat resistant alloys.

4 Incredible reliability in turning of heat resistant alloys TUNGALOY Special surface technology Nano-multi-layered AlTiN coating with high Al content - Increases hardness by 2% - Prevents micro cracks from developing Long tool life & stable machining " Improved adhesion strength Prevents notch wear that tends to occur in machining heat resistant alloys Newly developed substrates APPLICATION AREA High Cutting speed AH85 AH815 Low Continuous Machining mode 4 AH8SERIES Interrupted AH815 The 1st recommendation for heat resistant alloys Versatile grade with high wear and fracture resistance AH85 Grade with high hardness and excellent wear resistance

5 CHIPBREAKERS.2 For finishing to medium The 1st recommendation Unique protrusions on the rake face Reduces the contact area of rake face and chips Optimized rake face geometry and protrusion Provides low force and stable chip control For finishing Special protrusion Provides excellent chip control in machining depth of cut less than the corner Large rake angle and inclination Reduces force ACCELERATED MACHINING APPLICATION AREA AND CHIP CONTROL s for negative inserts (CNMG, DNMG, SNMG, TNMG, WNMG, VNMG) PSF PSS PS Steep protrusion Ensures stable and optimal chip control Unique 2-step rake angle Creates a steady curl of chips credit to its reduced contact area on the rake face to light Remarkable chip breaking Arc shaped protrusion allows stable chip control even at small depths of cut Stable machining with low force Optimized inclination and rake angle reduces forces and controls the chip flow when finish to medium Provides high reliability with low force Ideal combination of optimum rake angle and tough edge Stable chip control in a wide range of conditions Uniquely designed protrusion creates smooth chip curling Depth of cut: ap (inch) Feed: and chipbreakers cover finishing to medium. *Inserts with an I.C. diameter more than ø.5" are recommended for D.O.C..157" or more New Main chipbreakers for positive inserts (CCMT, DCMT, VCMT) Depth of cut: ap (inch) PS PSS PSF Feed: - PSF, PSS, and PS chipbreakers cover finishing to medium. - Complementary chipbreaker: All-round type 5
