The OSG UNC A-Spiral Flute Threading Tap is engineered for high-performance tapping of UNC coarse threads in blind holes, delivering precise results and long tool life for production runs. Designed for professional machinists and shop floors, this tap combines powder-metal toughness with a TiCN coating to handle demanding materials and high-speed operations.

• Thread type & size: UNC A (Unified National Coarse), right-hand orientation, DIN 2184-1 specification, M3 x 48 mm length
• Material: Powder-metal construction for exceptional hardness, wear resistance, and durability through repeated use
• Coating: TiCN coating reduces friction and increases surface hardness, extending tool life and enabling smoother cuts
• Flute design: Right-hand spiral flute provides efficient chip evacuation in blind-hole tapping, helping prevent clogging and improving thread quality
• Application: Optimized for tapping blind holes with UNC A threads, suitable for high-speed and high-precision operations in metalwork
• DIN standard: Complies with DIN 2184-1, ensuring compatibility with common precision-thread specifications

With this tap, users benefit from cleaner, more accurate threads, reduced tool wear, and less rework in production and maintenance tasks. The TiCN coating enhances performance in tougher materials by lowering cutting resistance, while the spiral flute design minimizes chip buildup inside blind holes. The powder-metal body delivers toughness for repetitive tapping cycles, making it a reliable choice for demanding manufacturing environments.
