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.
