COBALT TiAlN Coated Spiral FluteBORDO COBALT TiAlN Coated Spiral Flute
- 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.

Step Drill BitsMILWAUKEE Step and Drill Bit 10PC Set
Milwaukee step drill bits with Jam-Free performance feature a dual-flute design delivering up to 2x faster holes, up to 4x longer life and up to 50% more holes vs. competitors. Ideal for drilling small and large-diameter holes in steel and plastic, these bits are optimised for cordless drills in high speed. The Rapid Strike™ tip allows for a fast and accurate start that generates less heat, resulting in longer bit tip life. Black oxide coating also enhances durability, hole quality and bit life. For user convenience and accuracy, each bit has laserengraved reference marks you can see while drilling. The 3-flat SECURE GRIP™ shank ensures a solid connection with the drill chuck. Thunderweb HSS Jobber Drill Bits are optimised for a wide variety of drilling applications such as ferrous & non-ferrous metals, plastics and wood. The THUNDERWEB design is characterised by a conical shaped web which gets thicker towards the top of the drill bit. Standard Jobber Drill Bits have a constant thickness throughout their length.
