6.80mm InoxPro HSS TiAlN Coated Jobber Drill

About this item:

• Economical solution for stainless steel drilling.
• Optimised for superior performance in stainless steel (inox) and other hard metals.
• Bordo InoxPro drills are ground from premium quality M2 high speed steel. HSS can withstand higher operating temperatures than carbon steel without losing its temper (hardness).
• The 130º drill point angle provides an aggressive cutting action that reduces the chance of the bit slipping or work-hardening the material.
• The 40º fast helix ensures efficient drilling minimising heat generation.
• Titanium Aluminium Nitride (TiAlN) Coating has a violet/grey finish with a higher hardness than both TiN and TiCN coating utilises aluminium which imparts greater oxidation stability.
• This stability is a result of a very thin film (of Aluminium Oxide) which is formed on the surfaceof the TiAlN. This film is self repairing which leads to increased tool service life.
• This high performance coating is able to withstand much higher temperatures which allows increased speeds and feeds and semi-dry machining operations.
