    Tapping the Hardest Aerospace Materials

    The VT-AFT tap was designed to face solution-treated high-temperature alloys like A286, 300 series stainless steel and titanium aerospace fastener applications.  

    This tap is equipped with a high-vanadium HSS-E material for greater wear resistance and a precision-ground spiral geometry to push chips forward and reduce galling.

    Features & Benefits

    • TiN CrC/C coating to reduce galling and prevent build-up on edges
    • Spiral-point geometry for low cutting forces while pushing chips forward
    • Precision-ground spiral geometry allows tapping of solution-treated A286, 300 series stainless steel and titanium
    • High vanadium for higher wear resistance
    • Increased chamfer length to reduce chip load

    Is it possible to overcome the strict aerospace industry conditions and save money at the same time?

    The safest form of global transportation consists of many sensitive connections. Strict parameters must be followed to create the right tool to build these connections.

    The WIDIA Aerospace Fastener Tap incorporates features that allow it to do just that:

    • Patented spiral point geometry
    • Proprietary TiNCrC/C coating
    • Precision ground spiral geometry

    These features lead to outstanding benefits such as highly reliable process security and increased tool life. Say goodbye to large storage capactities and hello to better inventory planning with VT-AFT.
