Engineered for precision blind-hole threads, the OSG Metric Spiral Flute Threading Tap (M4 x 0.7) combines cobalt-enhanced HSS with a Steam Oxide Coated Plus finish to deliver reliable, long-lasting threading performance in demanding materials.

• Thread size: M4 x 0.7 metric spiral-flute tapping tap designed for blind holes, delivering clean, accurate threads in tight cavities.
• Material: HSS‑E (high-speed steel with cobalt) for higher hardness and improved heat resistance during heavy cutting.
• Finish: Steam Oxide Coated Plus enhances wear resistance, lubricity, and heat dissipation to extend tool life.
• Flute design: Spiral flute geometry promotes efficient chip evacuation and reduces the risk of jamming in deep or restricted holes.
• Application: Ideal for creating reliable internal threads in metals and common machinable alloys within blind-hole applications.
• Brand: OSG, a trusted name in precision threading tools for consistent, high-quality results.

The combination of cobalt-enhanced steel and the Steam Oxide finish provides steadier performance under higher cutting temperatures, smoother chip removal, and longer tool life. Expect precise, clean threads with reduced risk of wear or fracture, enabling more efficient production runs and fewer reworks in automotive components, enclosures, electronics housings, and other assemblies that rely on durable blind-hole threads.
