Abstract: A threading tap comprises a cylindrical shaft and a threading portion. At least the threading portion comprises a compound material comprising a core of high speed steel or tool steel and a cover of "Coronite".RTM., i.e., a hard material with 30 to 70% by volume of submicronic hard materials in the form of carbides, nitrides and/or carbonitrides of Ti, Zr, Hf, V, Nb, Ta, Cr, Mo and/or W in a metallic matrix based on Fe, Co and/or Ni. The chip surfaces adjacent to the cutting edges of the cutting threads have a negative rake angle. The threading tap has proven to be excellent at the threading of titanium-based alloys.

Abstract: A low torque tap includes a shank portion with a driving square and a thread cutting portion. The thread cutting portion includes a threaded body with one or more asymmetrical straight flutes that run essentially parallel to a longitudinal axis of the tap. The thread cutting portion also includes one or more short angular flutes or spiral points and a tapered chamfer. For tapping steel alloys, the cutting edges of the straight flutes and the spiral points have a rake or chordal hook angle of between about 5 and 15 degrees. For tapping ferrous materials, the tap is made from molybdenum-enriched high-speed steel and may be coated with a wear-resistant, friction-reducing layer. A second, outer layer, such as molybdenum disulfide, may be applied over the wear-reducing layer for further reduction in friction. For tapping non-ferrous materials, the tap may be coated with a layer of material containing carbon.
