Engineered for precision BSF threading in through-holes, the OSG BSF A-Spiral Point Tap delivers dependable, accurate results for professional machinists and shop environments that demand consistent performance. Its powder-metal body paired with a TiCN coating provides durability and reliable cutting performance across a wide material range.

• Thread type: BSF (British Standard Fine) with an A-Spiral Point design that efficiently directs chips forward and minimizes clogging during tapping.
• Material: Powder metal body offering high strength, wear resistance, and better heat tolerance under demanding tapping conditions.
• Coating: TiCN coating increases hardness, reduces friction, and extends tool life for sustained cutting performance.
• Size: 5/8 x 14 (BSF) through-hole tap, designed for standard BSF thread applications.
• Drive direction: Right-hand threading compatible with common machining setups.
• Standards: DIN2184-1 compatibility ensures correct form and a reliable finish for through-hole threads.

This tap enables faster, cleaner taps with fewer interruptions from chip buildup, thanks to its spiral-point geometry and robust construction. The combination of powder-metal toughness and TiCN coating supports higher cutting speeds and longer intervals between tool changes, delivering precise BSF threads in through holes across steel, cast iron, and compatible alloys. Ideal for shops prioritizing reliability, consistency, and efficient production.
