Engineered for precision UNF threading in blind holes, the OSG A-Spiral Flute Threading Tap is built for machinists who demand dependable performance in challenging layouts. With a TiCN-coated powder metal body and a right-hand thread, this tap delivers durable cutting and reliable chip evacuation.

• Thread Type: UNF (Unified National Fine) with A-Spiral flute and right-hand rotation for tapping in blind holes.
• Flute Design: A-Spiral flute geometry enhances chip evacuation, reducing the chance of clogging in confined blind-hole applications.
• Material: Powder metal construction provides exceptional wear resistance and durability under demanding cutting conditions.
• Coating: TiCN (Titanium Carbonitride) coating increases hardness, lowers friction, and extends tool life during high-speed machining.
• Size: 9/16" diameter with 12 threads per inch (9/16-12 UNF), DIN2184-1 standard compatible.
• Application: Specifically designed for blind-hole tapping, delivering stable performance where chip clearance is critical.

This tap is ideal for production environments and maintenance work where reliable UNF threading in tight or recessed holes is essential. The combination of TiCN coating and powder metal core delivers a balance of toughness and low friction, supporting longer tool life and consistent thread quality even at higher feed rates. Use with proper lubrication to maximize finish and minimize wear, and rely on the spiral flute for smooth chip removal during fast, repetitive tapping cycles.
