Bordo 4-12 x 1mm Spiral Flute HSS Cobalt TiAlN Coated Step Drill, 2602-M1

Description

About this item:

• HSS-Co5 (Cobalt) Titanium Aluminium Nitride Coated (TiAlN) Spiral Flute Step Drill 4-12mm
• 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.
