The OSG Threading Tap BSW A-Spiral Point is a precision tool designed for machinists who need accurate British Standard Whitworth (BSW) threads in through holes. Featuring an A-Spiral Point geometry, a TiCN coating, and a powder-metal body, this tap delivers dependable performance in demanding materials and high-speed tapping cycles.

• Thread Type: BSW (British Standard Whitworth) threading with A-Spiral Point geometry for efficient start and chip evacuation in through-holes
• Material: Powder-metal body providing wear resistance and toughness for demanding tapping environments
• Coating: TiCN coating to reduce wear, lower friction, and extend tool life during cutting
• Size: 7/16" major diameter, 14 TPI (7/16 x 14), DIN2184-1 compliant for through-hole applications
• Orientation: Right-hand thread for standard machining setups
• Application: Specifically designed to produce precise, clean BSW threads in through-holes across common metals

Using this tap delivers consistent, accurate thread quality with efficient chip handling thanks to the spiral-point design. The TiCN coating and powder-metal construction support longer tool life and reliable performance in high-speed tapping, helping you reduce rework and maintain production momentum in through-hole assemblies.
