The OSG Threading Taps BSW A-Spiral Flute are precision tapping tools engineered to cut British Standard Whitworth threads in blind holes. Designed for professional use, they deliver clean, accurate threads with dependable durability in challenging, non-through-hole applications.

• Thread Type: British Standard Whitworth (BSW) threads per DIN2184-1, 3/8" diameter with 16 TPI, right-hand
• Flute Design: A-Spiral flute for efficient chip evacuation in blind holes, reducing binding and improving reliability
• Material: Powder metal substrate for enhanced strength, wear resistance, and long tool life
• Coating: TiCN (Titanium Carbonitride) coating lowers friction and increases hardness for faster cutting and extended tool life
• Application: Optimized for blind-hole tapping where chip clearance is more challenging
• Usage Orientation: Right-hand threading direction suitable for standard BSW projects

This combination of material, coating, and flute geometry enables higher cutting speeds, better heat tolerance, and consistently defined threads in demanding shop environments. The TiCN coating reduces wear under tough materials, while the powder-metal core provides resilience and extended service life. Ideal for repairs, chassis work, and precision assemblies requiring reliable, non-through BSW threads.
