Product Specifications:
This HSS spiral flute tap features a **35° spiral angle** – significantly higher than conventional designs – providing superior chip evacuation in deep blind holes. Manufactured to ISO529 standard with TiN coating, it is designed for precision threading in metric fine threads. The 3‑flute design balances chip space and core strength, while the TiN coating (gold) reduces friction and increases wear resistance.
The M10x1.25 tap has an overall length of 80mm and a working length of 25mm, optimized for deep blind holes (up to 2.5× diameter) in stainless steel, carbon steel, alloy steel, and aluminum alloys. The 35° spiral angle actively lifts chips out of the hole, preventing clogging and improving thread quality – particularly critical in deep-hole applications.
Typical applications include deep blind holes in hydraulic components, mold bases, and precision machinery. The ISO529 standard ensures compatibility with metric fine thread specifications. Custom options include alternative coatings (TiAlN, AlCrN), left‑hand flutes, and special thread tolerances.
Spiral flute taps are ideal for blind holes (chip evacuation upward), while spiral point taps are best for through holes.Read full guide →
