Bordo Step Tip Step Drill 10mm Deep Cut 9-19mm x 2mm HSS-Co5 (Cobalt) TiAlN Coated 1/4″ Hex Shank, 2612-MD3

Description

About this item:

• Step Tip Step Drill 10mm Deep Cut 9-19mm x 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.
