The OSG Threading Tap Metric Fine A-Spiral Flute is designed for precise fine-thread cutting in metric blind holes, ideal for engineers and machinists who demand clean, reliable results in challenging internal threads.

• Thread size and type: Metric fine thread, M9 x 1, right-hand orientation for standard blind-hole tapping
• Flute design: A-Spiral flute for efficient chip evacuation and reduced clogging in tight blind holes
• Material: Powder metal construction offering robust wear resistance and long tool life
• Coating: TiCN (Titanium Carbo-Nitride) coating provides increased hardness and lower friction at high speeds
• Application: Specifically engineered for tapping blind holes to DIN374 standards, ensuring consistent thread quality
• Head geometry: Precision ground flute and flute length optimized for accurate starting and stable cutting

This combination of material, coating, and flute geometry translates to dependable performance in fine-thread applications. The TiCN coating reduces cutting temperatures and wear, helping maintain sharpness across multiple holes, while the powder-metal body delivers a balance of toughness and wear resistance. The A-Spiral flute design enhances chip clearance, minimizing heat buildup and the potential for tool breakage in blind-holes jobs.
