The OSG Threading Tap BSF A-Spiral Flute is a precision tool designed for machinists who cut British Standard Fine threads in blind holes. Built for reliability in non-through applications, it delivers clean, accurate BSF threads with extended tool life.
- Thread format: BSF (British Standard Fine), DIN2184-1, 7/16 x 18
- Flute design: A-Spiral flute for efficient chip evacuation in blind holes
- Material: Powder metal construction for high hardness and exceptional wear resistance
- Coating: TiCN (Titanium Carbonitride) coating reduces friction and boosts heat resistance
- Orientation: Right-hand threading for standard cutting direction
- Application: Optimized for blind holes to minimize chip packing and rework
With this tap, you’ll benefit from faster cutting speeds and less heat buildup thanks to the TiCN coating, improved chip evacuation from the spiral flute, and longer service life from the powder metal substrate. The result is precise, clean BSF threads that securely accept fasteners, helping you complete assemblies accurately and efficiently in restricted-access hole situations.
