OSG Metric Spiral Flute Threading Tap is designed for precision threading in blind holes, built for machinists, hobbyists, and production shops that demand reliable, repeatable results on small parts. Crafted from cobalt‑enhanced HSS and finished with a steam oxide coating, this tap delivers durability and heat resistance for demanding metalworking tasks.

• Size: M2 x 0.4 — metric threading tailored for compact assemblies and fine-thread applications.
• Material: HSS‑E (high‑speed steel with cobalt) for improved hardness and edge retention at elevated cutting temperatures.
• Coating: Steam oxide finish provides wear resistance and smoother operation under load, helping extend tool life.
• Flute Design: Spiral flute promotes continuous chip evacuation, reducing stalling in blind holes and improving hole quality.
• Application: Ideal for threading blind holes in thin-walled or precision components in metalworking, electronics enclosures, and small hardware assemblies.
• Brand: OSG — a trusted name in advanced threading technology with consistent performance.

The benefits of choosing the OSG Threading Tap include consistent start-to-finish thread quality in blind holes, reduced tap breakage from better heat management, and longer tool life thanks to the HSS‑E composition and steam oxide coating. The spiral flute design ensures efficient chip removal, keeping cutting edges clear and maintaining steady guidance through tight holes. This makes it ideal for routine production tasks and precision prototyping alike.
