The OSG Threading Tap BSW A-Spiral Point is a high-performance tapping tool designed for machinists who need precise British Standard Whitworth threads in through holes. With a spiral-point geometry, a powder-metal body, and a TiCN coating, it delivers durable, efficient performance for demanding production environments.

• Thread Type: BSW (British Standard Whitworth) threads designed for through-hole tapping per DIN2184-1.
• Size and Pitch: 5/8" diameter with 11 TPI (5/8 x 11) for standard Whitworth specifications.
• Material: Powder-metal substrate providing excellent wear resistance and heat tolerance for extended tool life.
• Coating: TiCN coating reduces friction and wear, enabling higher cutting speeds and longer tool life.
• Cutting Geometry: A-Spiral Point design that promotes efficient chip evacuation and smooth thread starts in through holes.
• Drive: Right-hand threading aligned with conventional tapping workflows.
• Applicability: Suitable for a range of metal workpieces requiring precise Whitworth threads with clean, consistent results.

These taps combine a robust powder-metal core with a hard TiCN coating to deliver dependable performance across production runs. The A-Spiral Point design minimizes chip buildup, reducing insert stoppages and cross-threading risk while helping threads start accurately in through holes. Ideal for machine shops and manufacturing environments that require 5/8" diameter, 11 TPI Whitworth threads to DIN2184-1, the tap supports efficient, high-speed tapping with consistent, high-quality thread formation.
