- 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.
- This coating works by forming a thin surface layer of Alumina (Al2O3), or Aluminium Oxide ceramic.
- As the layer wears it continuously reforms.
