Insert Grade QX5020 (ISO P10-P35 M10-M30 K10-K30) CVD Coated.An excellent general purpose grade for medium roughing on Steels, Stainless and Cast Irons.
A 19 piece metric heavy duty drill set made of 5% cobalt material with excellent heat resistance. Ideal for drilling steels with tensile strength up to 1,400 N/mm2, very hard bronze, stainless steels as well as heat and acid resistant steels. The high speed steel and cobalt construction allows for greater rigidity when cutting through harder materials.
Features and Benefits • Manufactured from high speed steel with 5% cobalt for added strength • Excellent heat and wear resistance for prolonged tool lifespan • Supplied in a robust carry case for easy portability and storage
