The OSG BSF A-Spiral Flute Threading Tap is engineered to cut British Standard Fine threads in blind holes with precision and reliability. Built on a powder-metal body and finished with a TiCN coating, this right-hand tap from OSG delivers durable performance for demanding internal threads in metal parts.

• Thread Type: BSF (British Standard Fine) with an A-Spiral flute for efficient chip evacuation in blind holes
• Size: 1 x 10, DIN2184-1 compatibility, right-hand threading
• Material: Powder metal construction for high hardness, wear resistance, and toughness
• Coating: TiCN (Titanium Carbonitride) reduces friction and improves heat resistance for longer tool life
• Flute Design: A-Spiral flute enhances chip removal and supports smoother cutting in non-through holes
• Hole Type: Designed specifically for blind holes to prevent chip build-up and ensure clean threads
• Standards: DIN2184-1 compliance for consistent tapping performance and interchangeability

This tap is ideal for applications where precise BSF threads are required in closed-end or blind holes, such as automotive components, machinery housings, or precision assemblies. The combination of powder-metal durability and TiCN coating supports longer tool life under higher cutting speeds, while the spiral flute geometry minimizes chip accumulation and chatter, helping you achieve accurate, smooth-threaded results with fewer reworks.
