• 4-30mm 3 Pce Spiral Flute HSS Cobalt Step Drill Set
  • HSS-Co5 (Cobalt) Titanium Aluminium Nitride Coated (TiAlN) Spiral Flute Step Drill Set
  • Bordo Cobalt Spiral Flute Titanium Aluminium Nitride (TiAlN) coated step drills offer unparalleled performance when drilling hard metals such as stainless steel.
  • HSS-Co5 material provides increased performance and tool life when machining tough steels.
  • Bordo step drills are ideal for electrical contractors, sheetmetal workers and auto mechanics.
  • Step drills are designed for drilling repetitive holes in steel, stainless steel, copper, brass, aluminium, plastic, plexiglas, laminates and many other thin materials.
  • High performance point for faster starting and reduced bit wander.
  • No pilot hole required.
  • Stepless drilling in the thinnest sheets.
  • Burr-free drilling without sheet deformation.
  • Automatic deburring.
  • Spiral flutes enable easier tool penetration.
  • Titanium Aluminium Nitride (TiAlN) is a thin film coating that was developed from Titanium Nitride.
  • TiAlN offers higher temperature resistance than TiN, as well as slightly higher hardness and especially higher hot hardness (i.e. the hardness at high temperatures).
  • It is primarily used in high temperature environments above the limits of TiN usage.
