BORDO Red Band HSS-Co TiAlN Tough Treatable Steel Drilling

  • Bordo Metric Red Band HSS-Co TiAlN Coated Twist Drills for Tough Treatable Steel.
  • DIN338
  • 130° UX point with two helical parabolic flutes with 33 degrees of helix angle.
  • The mechanical properties of materials are influenced diversely by the addition of alloying elements and heat treatment processes, resulting in some high-strength, quenched and tempered steels or hardened steels.
  • This range has its own unique set of machining requirements which are satisfied by the Red Band – Tough Treatable Steel – Series.
  • TiAlN coating increases tool surface hardness to 87Rc.
  • For machining materials with Hardness < 470 HB : Tensile Strength <1500 N/mm2.
