The OSG Threading Tap UNF A-Spiral Flute is purpose-built for precision tapping of UNF threads in blind holes, delivering reliable results in tight cavities and precision assemblies. It combines powder-metal durability, a TiCN coating, and a right-hand threading design to handle high-speed machining per DIN2184-1.

• Thread Type: UNF (Unified National Fine) A-Spiral Flute for efficient chip evacuation in blind holes.
• Material: Powder-metal construction delivers exceptional wear resistance and heat tolerance.
• Coating: TiCN (Titanium Carbonitride) coating reduces friction and extends tool life in demanding materials.
• Flute Design: A-Spiral flute optimizes chip flow and minimizes clogging in deep blind holes.
• Size / Standard: DIN2184-1, tapping size 1-8 UNF for right-handed threads.
• Application: Right-hand tapping for UNF threads in blind holes across automotive, aerospace, and precision-machining contexts.

With the combination of powder-metal composition and TiCN coating, this tap delivers dependable performance across repeated use, maintaining thread quality and reducing service downtime. The spiral flute design streamlines chip evacuation in blind holes, lowering the risk of chip jamming and tool breakage. Users benefit from longer tool life, fewer re-taps, and cleaner, more accurate UNF threads in challenging workpieces.
