Product Specifications:
This HSSE spiral flute tap is manufactured to DIN 15D geometry, offering a versatile solution for general-purpose threading in a wide range of materials. It is compatible with DIN 371 (for M3–M10) and DIN 376 (for M12–M24) standards, making it suitable for both small and large diameter applications. The 15° spiral angle ensures efficient chip evacuation in blind holes, while the 3‑flute design provides balanced cutting action and good thread finish.
The M12x1.25 tap features an overall length of 100mm and a working length of 22mm, optimized for medium-depth blind holes in carbon steel, alloy steel, stainless steel (304, 316), aluminum alloys, and cast iron. The uncoated HSSE substrate offers good wear resistance and toughness for general machining. For higher speeds or abrasive materials, TiN or TiAlN coatings can be applied upon request.
Typical applications include automotive components, general machinery, hydraulic parts, and mold bases. 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 HSSE tap delivers consistent performance and reliable 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 →
