Engineered for precision threading in metric blind holes, the OSG Threading Tap delivers reliable, fine-pitch performance for small-diameter applications. With a powder-metal body, TiCN coating, and an A-Spiral flute, it ensures clean cuts and long tool life in challenging materials.

• Tap type: Metric fine threading tap designed for blind holes, M4 x 0.5, ideal for precise small-thread work.
• A-Spiral flute: Spiral-flute design promotes efficient chip evacuation and minimizes clogging in tight blind-hole environments.
• Material: Powder metal construction delivers enhanced wear resistance and durability for demanding use.
• Coating: TiCN (Titanium Carbo-Nitride) coating increases hardness and reduces friction for smoother cutting at higher speeds.
• Hand: Right-hand threading, suitable for standard single-direction tapping in commonly encountered holes.
• Standards: DIN371 compliance supports consistent dimensional accuracy for metric blind-hole threads.

This tap is built to deliver consistent, high-quality thread form with less rework. The combination of a hard-wearing powder-metal body and a tough TiCN coating reduces wear, extends tool life, and maintains precise thread dimensions through repetitive cuts. The A-Spiral flute enhances chip clearance, helping you maintain steady feeds and speeds, even in deeper blind holes. Ideal for production runs or precision repairs where reliable, repeatable performance matters.
