The OSG Threading Tap BSW A-Spiral Flute is a right-hand tapping tool engineered to cut British Standard Whitworth threads in blind holes. Built from high-performance powder metal and TiCN-coated for durability, it delivers precise, clean threads even where access is limited.

• Size and Thread: 7/8 x 9 BSW (DIN2184-1) for dedicated blind-hole applications
• Flute Design: A-Spiral flute promotes efficient chip evacuation in blind holes
• Material: Powder metal construction for toughness and wear resistance
• Coating: TiCN coating reduces friction and increases hardness for longer tool life
• Orientation: Right-hand threading for standard internal threading operations
• Application: Specifically designed for blind holes where through-holes are not possible

With TiCN-coated powder-metal performance, this tap offers longer service intervals and consistent thread quality across production runs. The A-Spiral flute minimizes chip buildup, lowering the risk of tap breakage and providing smoother cutting in deep or restricted cavities. Reduced friction allows higher cutting speeds and cooler operation, helping you achieve clean, accurate BSW threads in steel, cast iron, or other compatible metals. This makes it ideal for maintenance, repair, or manufacturing environments where reliable blind-hole threading is required.
