Description

The OSG Threading Tap, Metric A-Spiral Flute, is engineered for precision tapping in metric blind holes. Featuring a +0.1 oversize tolerance, TiCN-coated powder-metal construction, and a right-hand thread, it delivers reliable, high-quality threads for DIN371 blind-hole work—M5 x 0.8.

  • Thread size / pitch: M5 x 0.8
  • Flute style: A-Spiral flute designed for efficient chip evacuation in blind holes
  • Oversize tolerance: +0.1 to promote consistent engagement and clean thread formation
  • Material: Powder metal for enhanced strength and wear resistance
  • Coating: TiCN coating increases surface hardness and reduces friction
  • Machining direction: Right-hand thread for standard tapping operations
  • DIN standard: DIN371-compliant performance in metric blind-hole applications
  • Application: Specifically suited for blind-hole tapping in metal components and housings

With its A-Spiral flute, TiCN-coated powder-metal body, and precise +0.1 oversize tolerance, this tap minimizes chip buildup, reduces the risk of breakage, and extends tool life even under high-speed machining. The result is consistent thread quality and smoother assembly in automotive, electronics, and other precision-manufacturing contexts where blind-hole threads are required.
