Bordo HSSE-V3 TiAlN Coated Blue Band Spiral Flute Tap

• HSSE-V3 HSSE with 3% Vanadium high performance tap.
• TiAlN (Titanium Aluminium Nitride) coating provides higher temperature resistance and improved surface hardness.
• Optimised for machining stainless steel
• Spiral flute with 40° helix angle.
• Designed for tapping blind holes where the right hand spiral forces swarf out of the hole and prevents clogging which may cause breakage or spoiled threads.
• Designed to withstand the high stress and high heat associated with CNC production tapping.
• The machining of stainless steels is difficult due to its work hardening properties, toughness, and poor thermal conductivity, which places high demands on the cutting tools.
• TiAlN coating increases tool surface hardness to 87Rc.
• For machining materials with Hardness < 350 HB: Tensile Strength <1250 N/mm².

About Drill Bit Surface Treatment

• Violet / Grey TiAlN (Titanium Aluminium Nitride - TiAlN) A violet/grey finish with a higher hardness than both TiN and TiCN coating utilises aluminium in the coating which imparts greater oxidation stability.
• This stability is a result of a very thin film (of Aluminium Oxide) which is formed on the surface of 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.
• TiAlN coating is especially useful when machining cast iron and tough steels.

About Stainless Steel Blue Band

• The machining of stainless steel is difficult due to its work-hardening properties, toughness and poor thermal conductivity, which places high demands on the cutting tools.
• The Blue Band Series has been specifically designed to suit these difficult machining requirements.
• TiAlN coating increases tool surface hardness to 87Rc.
• For machining materials with Hardness.
