Engineered for precision left-hand threading in blind holes, the OSG Metric A-Spiral Flute Threading Tap delivers durable performance with a design tailored for reliability in challenging depths.

• Threading Tap Type: Metric A-Spiral Flute, Left-Hand (LH) configuration for creating left-handed threads in blind holes
• Coating: TiCN coating enhances wear resistance and extends tool life under demanding cutting conditions
• Material: Powder metal substrate provides toughness and stable flute geometry for consistent cuts
• Size / Pitch: M5 x 0.8, DIN371-compatible for standard threading accuracy
• Hole Type: Designed specifically for blind-hole threading to minimize breakout and ensure clean terminations
• Flute Design: A-Spiral flute geometry promotes efficient chip evacuation and reduces chip packing in deep holes
• Standards: DIN371 compliance ensures reliable interchangeability with compatible taps and tooling
• Applications: Suitable for a variety of materials where precise left-hand threads are required, delivering dependable performance across demanding projects

The combination of a TiCN-coated powder-metal body and an optimized spiral flute means fewer tool changes and longer runs between sharpening, even in deeper blind-hole operations. The left-hand threading capability is ideal for assemblies that require reverse threading or special fastener configurations, while the robust coating and substrate resist wear from tougher materials. With accurate tolerances and smooth operation, this tap helps you achieve consistent thread quality, reduced downtime, and improved productivity in machining environments.
