Product Specifications:
This A30 HSSE spiral flute tap is manufactured to DIN 15D standard, featuring a 4‑flute design for reduced cutting load and improved chip splitting in medium-diameter threading. The A30 grade (high-cobalt powder metallurgy) provides excellent red hardness and wear resistance, suitable for general metal cutting applications including carbon steel, alloy steel, stainless steel, aluminum alloys, and cast iron. The 15° spiral angle ensures efficient chip evacuation in blind holes.
The M16x1.5 tap has an overall length of 100mm and a working length of 22mm, optimized for medium-depth blind holes in automotive components, machinery parts, hydraulic fittings, and structural steel. Although supplied uncoated, TiN or TiAlN coatings can be applied upon request to reduce friction and extend tool life in abrasive materials like stainless steel and cast iron.
Custom options include alternative coatings (CrN, AlCrN), left‑hand flutes, reduced shank diameters, and special thread tolerances (6HX, 4H). For high-volume production runs, this A30 HSSE tap delivers reliable performance and consistent thread quality.
Spiral flute taps are ideal for blind holes (chip evacuation upward), while spiral point taps are best for through holes.Read full guide →
