OSG Metric A-Spiral Flute Threading Tap, LH (Left-Hand), M5 x 1, is engineered for precise blind-hole threading. Crafted from high-grade Powder Metal and TiCN coated, this tap delivers durable performance and reliable cutting in challenging blind-hole applications.

• Thread format: Metric M5 x 1 with A-Spiral Flute design, optimized for left-hand threads in blind holes (DIN371 compliant).
• Material: Powder Metal construction for enhanced hardness and wear resistance.
• Coating: TiCN coating to reduce friction and extend tool life.
• Flute design: A-Spiral flute provides efficient chip evacuation in confined blind-hole environments, minimizing clogging and insipient binding.
• Hand orientation: Left-hand ( LH) threading capability for specific assembly needs or reverse-threading operations.
• Application: Suitable for a variety of materials where precise blind-hole threads are required and chip control is critical.

Designed for professional machinists, this tap helps achieve clean, accurate threads in hard-to-reach blind holes. The combination of a powder-metal substrate and TiCN coating supports long tool life, while the spiral flute and left-hand geometry deliver dependable cutting performance with reduced risk of clogging. Ideal for production runs and repair work that demand consistent thread quality with minimal rework.
