The OSG Threading Tap is a precision metric fine-thread tap designed for cutting in blind holes. Built for small-diameter work, this TiCN-coated, powder-metal tap delivers durable performance with tight tolerances in every cut.

• Thread type: Metric Fine thread with A-Spiral flute designed for blind holes
• Size: M3.5 x 0.35 pitch
• Material: Powder metal substrate for enhanced wear resistance and longevity
• Coating: TiCN (Titanium Carbo-Nitride) coating increases hardness and reduces friction
• Flute design: Right-hand spiral flute promotes efficient chip evacuation and minimizes built-up edge
• Hole compatibility: Specifically engineered for metric blind holes, delivering consistent threads
• Standards: DIN371 compliant for reliable interchangeability with other DIN taps
• Applications: Ideal for fine threading tasks in compact components and assemblies

This tap combines a hard-wearing powder metal body with a high-performance TiCN coating to withstand demanding cutting conditions. The TiCN layer enhances hardness and reduces friction, enabling smoother cuts at higher speeds and temperatures. The A-Spiral flute design excels at evacuating chips from blind holes, helping maintain a clean cutting edge and producing precise, repeatable threads. For production environments that require dependable, long-lasting tooling with tight tolerances, this tap from OSG offers a compelling, mission-critical option.
