The OSG Metric Spiral Flute Threading Tap is built for precise blind-hole threading in metalworking projects, delivering reliable performance for technicians and shops that demand consistency from start to finish. Sized M2.5 x 0.45, it’s ready for metric threads in compact applications.

• Material: HSS‑E (high-speed steel with cobalt) for improved hardness and wear resistance under demanding cutting conditions.
• Coating: Steam oxide coating enhances wear resistance and reduces friction for cooler, more stable cutting.
• Flute Design: Spiral flute geometry promotes efficient chip evacuation, minimizing clogging and heat buildup in blind holes.
• Size & Pitch: Metric threading tap, M2.5 x 0.45, optimized for precise, reliable threads in small-diameter holes.
• Application: Specifically suited to blind-hole threading tasks, delivering clean, accurate threads in a range of common metals.

With the combination of cobalt-enhanced HSS and a steam oxide coating, this tap delivers durable performance and consistent results across multiple holes. The spiral flute design helps keep chips moving away from the cutting edge, reducing the risk of tool or workpiece damage and extending tool life. This makes it a dependable choice for fine-pinish threaded connections in compact assemblies, electronics housings, and light-to-medium duty mechanical components.
