OSG’s Metric Spiral Flute Threading Tap in M9 x 1.25 is built for precise blind-hole threading in metal parts, delivering durable performance for professional shops and serious DIY projects alike.

• Thread size: M9 x 1.25 metric threading tap designed for blind-hole applications.
• Material: HSS-E (high-speed steel with cobalt) for superior hardness, wear resistance, and edge retention at higher cutting speeds.
• Coating: Steam oxide coating enhances surface hardness and provides improved wear and corrosion resistance.
• Flute design: Spiral flute geometry optimized for efficient chip removal, reducing clogging in confined blind holes.
• Application: Specifically suited for threading inside blind holes where chip evacuation is critical to avoid cross-threading and finished-thread quality issues.
• Durability: Robust construction with cobalt-enhanced alloy and coating to extend tool life in demanding materials.

This threading tap enables consistently clean, accurate M9 x 1.25 threads with reliable performance across steel and other challenging metals. The combination of HSS-E, steam oxide coating, and spiral fluting supports faster cutting, smoother chip evacuation, and longer tool life, making it a dependable choice for precision tapping in production or workshop settings. For best results, pair with appropriate tapping fluid and steady feed to maintain thread integrity and reduce wear.
