OSG Threading Tap Metric A- Spiral Flute - LH Powder Metal Left Hand - TiCN Coated - Blind Holes DIN376 - M20 x 2.5

OSG’s Metric A-Spiral Flute Threading Tap is engineered for precise blind-hole threading with a left-hand thread, built to perform reliably in demanding production environments.

• Size and pitch: M20 x 2.5
• Threading type: Metric A-Spiral Flute, left-hand threading for reverse-thread applications in blind holes
• Material: Powder Metal body for toughness and consistent cutting performance
• Coating: TiCN coating delivers enhanced hardness and wear resistance to extend tool life
• Chip evacuation: A-spiral flute design promotes efficient chip removal in confined blind-hole spaces
• Application: Suitable for threading in a variety of materials where blind holes are used
• Standards: DIN 376 compatibility to ensure reliable, standard-thread results

This tap delivers durable, repeatable performance in blind-hole applications, with a coating and construction designed to resist wear and maintain cutting efficiency across multiple jobs. The combination of TiCN coating and powder-metal craftsmanship supports longer tool life, while the spiral flute geometry minimizes chip packing and heat buildup for smoother, more consistent threads. Ideal for machinists and engineers seeking dependable threading performance in production or repair settings.
