Description
About this item:
- Step Tip Step Drill 10mm Deep Cut Tapping 3.3,4.2,5.0,6.8,8.5,10.2mm HSS-Co5 (Cobalt) TiAlN Coated 1/4″ Hex Shank
- HSS-Co5 (Cobalt) Titanium Aluminium Nitride Coated (TiAlN) step drills offer unparalleled performance when drilling hard metals such as stainless steel.
- Step Tip negates the need for a pilot drill in metals and provides extreme drilling speeds in ferrous and non-ferrous metals, plastic and all timbers.
- 1/4″ hex shank is ideal for use with impact drivers, quick change adaptors and bit holders.
- Deep Cut – suitable for drilling materials up to 10mm thick.
- Laser marked diameters on each step for fast identification.
- 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 materials.
- 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.
