The OSG Threading Tap Metric Fine A-Spiral Flute is a precision tapping tool engineered for metric fine threads in blind holes. Built for machinists and production environments, it delivers clean, accurate threads with dependable wear resistance and efficient performance in tight cavities.

• Thread size and pitch: M20 x 1.5, metric fine threading with right-hand cut
• Flute design: A-Spiral flute for rapid chip evacuation in blind holes, reducing clogging and chatter
• Material: Powder metal body for enhanced wear resistance and extended tool life
• Coating: TiCN (Titanium Carbo-Nitride) coating increases hardness and lowers friction for higher-speed cutting
• Hole type: Optimized for threading in metric blind holes to achieve precise, consistent results
• Direction: Right-hand tapping for standard threading applications
• Standards: DIN374-compliant design to ensure reliable interchangeability and performance

Designed for reliability in demanding environments, this tap helps you achieve precise thread quality with reduced break-in and wear. The TiCN coating delivers smoother cutting action under higher speeds and temperatures, while the powder-metal construction withstands repeated use across materials. The A-Spiral flute supports efficient swarf removal, minimizing downtime due to chip buildup and enabling cleaner cuts in tight blind-hole cavities. This makes the tool well-suited for production runs, automotive assemblies, tool-and-die work, and precision fixtures where tight tolerances matter.
