Drillco thread forming tap "form" the thread rather than cut it, which allows the thread to be created without producing any chips. Thread forming taps can run at faster operating rates than standard cut taps, and generally have a longer tool life, sometimes up to 5x longer in some applications. Ideal in materials such as aluminum, brass, copper, low carbon steels, Zinc, and 302-303 stainless steel. High-speed steel tools are good for most general Purpose applications, Offering a combination of hardness and toughness for wear resistance. Uncoated tools feature just the base substrate without any additional treatment or coatings and are suitable for a wide range of applications. Comes with round with square end shank. Straight flute tools allow chips to collect in the flutes as they cut and are well suited for most applications in shallow cuts.
