The OSG Threading Tap UNF A-Spiral Point is a high-performance tapping solution designed for through-hole applications in precision machining. Built for professionals who demand durability and consistent thread quality, this tap delivers reliable results in UNF configurations with a focus on long tool life and smooth operation.

• Thread form and size: UNF A-Spiral Point for 7/8" diameter and 9 TPI (7/8-9 UNF) with through-hole capability
• Material: Powder metal substrate emphasizes toughness and wear resistance for repeated use
• Coating: TiCN coating reduces friction, lowers heat buildup, and extends tool life
• Geometry: A-Spiral Point designed to efficiently evacuate chips in through-hole tapping
• Application: Right-hand threading optimized for standard machining setups and through-hole projects
• Standards: DIN 2184-1 compatibility ensures consistent dimensions and performance

With its combination of powder-metal durability, TiCN-coated cutting edges, and a spiral-point geometry, this tap delivers clean, precise UNF threads in through-holes while resisting wear under demanding cutting conditions. It’s suited for shops that require dependable threading performance across a range of common machinable materials, reducing downtime and delivering repeatable results in high-precision components.
