OSG Threading Tap BSF A-Spiral Flute - Powder Metal Right Hand -TiCN Coated - Blind Holes DIN2184-1 - 5/16 x 22

The OSG Threading Tap BSF A-Spiral Flute, made from powder metal and TiCN coated, is engineered for precise British Standard Fine threads in blind holes. Designed for professionals who demand reliability and clean, accurate threads in confined spaces.

• Thread type: British Standard Fine (BSF), right-hand, for blind holes (DIN2184-1) with a 5/16 x 22 size.
• A-Spiral flute design: Optimized for chip evacuation in non-through holes, reducing clogging and binding during tapping.
• Material: Powder metal substrate delivering enhanced wear resistance and long service life under demanding cutting conditions.
• Coating: TiCN (Titanium Carbonitride) reduces friction and improves heat resistance for higher cutting speeds and extended tool life.
• Hole type compatibility: Specifically suited for blind holes where chip removal is critical to prevent breakage and re-cutting.
• Right-hand threading: Optimized for conventional clockwise tapping workflows, ensuring straightforward, predictable performance.
• DIN standard: Conforms to DIN2184-1 geometry, ensuring consistent thread form and pitch with BSF specifications.

This tap helps machinists achieve accurate BSF threads in hard-to-reach blind-holes with fewer inserts or reworks. The combination of powder-metal construction and TiCN coating delivers durable performance, while the A-Spiral flute design supports smooth chip flow, mitigating common tapping issues such as chip packing and tap breakage. Ideal for precision assemblies in automotive, machinery, and general engineering where BSF threads are required in blind-hole applications.
