5.00mm HSS-Co TiAlN Coated Parabolic Flute Jobber Drill

About this item:

• High performance drill with no pecking.
• Suitable for materials up to 1200N/mm2.
• Designed for deep hole drilling with extremely efficient chip evacuation.
• Large parabolic flutes reduce the need for frequent drill withdrawal and peck cycle drilling.
• The heavy web and parabolic flute shape provide increased stability enabling drilling of accurate straight deep holes.
• 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.
