Product Specifications:
This HSSE spiral flute tap features a TiN (titanium nitride) coating with a distinctive gold appearance, providing reduced friction, increased surface hardness, and improved wear resistance. The 4‑flute design offers balanced chip splitting and reduced cutting load per flute, making it ideal for large-diameter threading in blind holes. The 15° spiral angle ensures efficient chip evacuation upward, while the robust core diameter provides high torsional strength necessary for M20 threads.
The M20x1.5 tap has an overall length of 125mm and a working length of 25mm, optimized for medium-depth blind holes in carbon steel, alloy steel (4140, 4340), stainless steel (304, 316), cast iron (GG25, GGG50), and aluminum alloys. The TiN coating allows for higher cutting speeds and extends tool life by up to 50% compared to uncoated HSSE taps, particularly in abrasive materials like ductile cast iron and stainless steel.
Typical applications include heavy machinery components, wind turbine housings, large hydraulic manifolds, and industrial gearboxes. Custom options include alternative coatings (TiAlN, AlCrN), left‑hand flutes, reduced shank diameters, and special thread tolerances (6HX, 4H). For high-volume production runs, this TiN-coated HSSE tap delivers consistent performance and excellent cost‑per‑hole value.
Spiral flute taps are ideal for blind holes (chip evacuation upward), while spiral point taps are best for through holes.Read full guide →
