CA5 is made for reliable processing of steel. The newly developed CVD-coated carbide grades with further improved properties give optimum results and high process security. The newly developed carbide substrate with 10% improved hardness at high operating temperatures, means the turning insert is more resistant to plastic deformation, tool life is improved and high-efficiency turning achieved. To achieve process security in production, Kyocera has always focused on optimum chip control with a wide range of chipbreakers for various applications. The CA5 series is raising the bar further with a newly developed chip breaker, new coating technology and much more.
