The OSG Threading Tap Metric A-Spiral Flute is a right-hand, powder-metal tap engineered for precise threading of blind holes. Built for production environments, it delivers durable wear resistance and consistent results across a range of materials.

• Thread Size & Standard: Metric M3.5 × 0.6 (DIN 371) for precise, industry-standard threads in blind holes.
• Flute Design: A-spiral flute enhances chip evacuation, reducing clogging in deep or blind-hole tapping.
• Material: Powder metal body combines strength and wear resistance for demanding applications.
• Coating: TiCN coating increases surface hardness and lowers friction for longer tool life and steadier performance at higher speeds.
• Hand: Right-hand tap compatible with common CNC and manual tapping setups.
• Application: Optimized for precision threading in blind holes, supporting clean, accurate threads with minimal rework.

These taps excel in high-speed production settings, delivering reliable thread quality and extended tool life thanks to the TiCN coating and robust powder-metal construction. The combination of M3.5 × 0.6 sizing, DIN 371 compliance, and the A-Spiral flute makes this tap a dependable choice for engineers and machinists working with blind-hole components across ferrous and non-ferrous materials alike.
