The OSG BSF A-Spiral Flute Tap is engineered for cutting British Standard Fine threads in blind holes. Built for durability and precision, it’s ideal for machinists and fabricators working in restricted cavities where chip evacuation matters.
- Thread specification: BSF (British Standard Fine) DIN2184-1, 5/8" major diameter with 14 TPI
- Flute design: A-Spiral flute for efficient chip evacuation in blind holes
- Material: Powder metal construction for high wear resistance and long tool life
- Coating: TiCN coating lowers friction and improves heat resistance for longer life
- Cutting direction: Right-hand thread (clockwise) for typical machining setups
- Hole type: Optimized for blind (non-through) holes to minimize chip packing
- Standards: DIN 2184-1 compliant BSF tapping solution from OSG
Equipped with a TiCN-coated powder-metal body and an A-sp spiral flute, this tap is designed to deliver consistent, clean threads with tight tolerances in blind holes. The flute geometry promotes rapid chip ejection, reducing clogging and heat buildup, while the coating reduces wear and extends useful life, letting you work faster with less downtime. Suitable for automotive, machinery maintenance, and light to medium production work where BSF threads are required, the tap helps you achieve accurate thread engagement and reliable fastener performance.
