Engineered for precision metalworking, the OSG Threading Tap — Metric Fine, A-Spiral Flute — delivers clean, accurate threads in metric blind holes. Designed for technicians and shops that demand dependable performance per DIN 371 in tight cavities.

• Threading type: Metric fine thread (M3 x 0.35), right-hand orientation
• Flute design: A-Spiral flute for efficient chip evacuation in blind holes
• Material: Powder metal body for enhanced durability and wear resistance
• Coating: TiCN coating increases hardness and reduces friction for smoother cuts
• Application: Specifically designed for tapping metric blind holes compliant with DIN 371
• Brand: OSG — trusted precision tooling for demanding threading tasks

The combination of a spiral flute, rugged powder metal construction, and a TiCN coating translates to reliable performance in tight spaces. Chip evacuation remains efficient, minimizing clogging and downtime, while the TiCN layer maintains cutting efficiency at higher speeds and temperatures. Expect consistently formed fine threads with extended tool life, enabling precise assemblies and reduced reworks in small-diameter, high-precision projects.
