OSG BSF Spiral Point Threading Tap in 5/8 x 14 is built for precision BSF thread production in through-hole applications. Crafted from HSS-E cobalt and finished with a Steam Oxide coating, it balances durability with heat resistance for reliable machining.

• Size & Thread: Through-hole tap for BSF threads, 5/8" major diameter with 14 TPI.
• Material: High-speed steel with cobalt (HSS-E) for improved wear resistance and tool life.
• Coating: Steam Oxide finish reduces wear and aids heat management during prolonged cuts.
• Thread Type: BSF (British Standard Fine) with spiral point design for efficient chip evacuation.
• Design Purpose: Optimized for through-hole tapping to deliver clean, accurate threads in demanding materials.

This tap provides consistent, high-quality BSF threads that meet the needs of critical machining tasks. The combination of cobalt-enhanced HSS, steam-oxide coating, and spiral point geometry helps maintain threading accuracy while extending tool life, reducing downtime and rework in production environments.
