Feature●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●Round shank with square end●Straight flute tools allow chips to collect in the flutes as they cut and are well suited for most applications in shallow cuts●Right-hand cut tools have a cutting action that engages when they are run in a clockwise directionDescription Also called pipe taps, National pipe taper taps are appropriate for Threading a wide variety of materials both ferrous and non-ferrous.
