WIDIA™ offers the VariTap(TAM) tap for processing multiple work materials, such as aluminum, stainless steel, and cast iron.
The design includes a proprietary spiral point geometry that lowers tapping torque, extending tool life while driving chips forward in through-holes. The geometry also aids chip evacuation to reduce bird-nesting in blind holes. Its coating and high-vanadium HSS-E blanks help improve wear resistance.
The tap can be used with all styles of tap holders, including tension/compression holders, rigid holders, and synchronous tap holders.
