OSG Threading Tap Metric Fine A-Spiral Flute - FORM E Powder Metal Right Hand -TiCN Coated - Blind Holes DIN371 - M2.5 x 0.35

The OSG Threading Tap Metric Fine A-Spiral Flute is a precision tool designed for engineers and machinists tackling fine-pitch blind-hole threads. Built for durability and consistent quality, it delivers clean, accurate internal threads in compact assemblies.

• Thread size and pitch: Metric fine thread M2.5 x 0.35, tailored for precise blind-hole tapping in small components.
• FORM E geometry: Optimized cutting geometry for smooth engagement and tight thread profiles, enhancing first-pass reliability.
• Flute design: A-Spiral flute provides efficient chip evacuation, reducing clogging in blind-hole applications and supporting higher-speed tapping.
• Material: Powder metal substrate delivers improved wear resistance and durability under repeated use.
• Coating: TiCN coating increases surface hardness and reduces friction, extending tool life and maintaining sharpness over time.
• Right-hand operation: Standard threading direction for most internal-threading tasks in a wide range of materials.
• DIN standard: DIN371 compatibility, aligning with common industry specifications for reliable interchangeability.

Designed for tasks where precision matters—such as electronics housings, micro-mechanical assemblies, and aerospace components—the TiCN-coated powder-metal tap maintains thread quality even in tough materials. Its geometry and flute work together to minimize chatter, improve hole fill, and produce consistent thread depth on blind holes, helping you reduce rework and production time.
