The OSG Threading Tap is a high-performance tool designed to cut British Standard Whitworth (BSW) threads in blind holes with precision and reliability. Its A-Spiral flute and TiCN coating enhance chip evacuation and tool life, making it ideal for challenging blind-hole work.

• Thread standard: BSW (British Standard Whitworth) with DIN2184-1 specification
• Size & pitch: 3/4" diameter, 10 TPI (Right-Hand)
• Flute design: A-Spiral flute for efficient chip removal in blind holes
• Material: Powder Metal construction for toughness and wear resistance
• Coating: TiCN (Titanium Carbonitride) coating to reduce friction and extend tool life
• Application: Optimized for blind-hole tapping to deliver clean, accurate threads

The combination of a powder-metal substrate and TiCN coating provides durable performance under higher cutting speeds and temperatures, helping you achieve consistent thread quality in hard materials. The A-Spiral flute design minimizes chip packing in blind holes, reducing the risk of tool binding and improving hole finish. With DIN2184-1 compatibility and a precise 3/4" x 10" specification, this tap is a dependable choice for restoration, repair, and fabrication tasks that require reliable BSW threading in inaccessible holes.
