The OSG BSP Spiral Flute Threading Tap in 5/8 x 14 is a precision tool built for blind-hole BSP threading. Designed for machinists and fabricators who demand reliable, accurate threads in challenging materials, it pairs durability with excellent chip control.

• Thread Type: BSP spiral flute threading tap engineered for blind-hole BSP threads, delivering consistent engagement and clean cuts.
• Material: HSS-E (high-speed steel with cobalt) for enhanced hot hardness and extended tool life in tough metals.
• Coating: Steam oxide coating reduces friction and improves wear resistance, helping maintain sharpness under load.
• Flute Design: Spiral flutes optimize chip evacuation, minimizing clogging in deep or obstructed holes for smoother tapping.
• Size and Pitch: 5/8" diameter with 14 TPI, suitable for standard BSP applications.

This tap excels in blind-hole scenarios common in plumbing, hydraulic, and mechanical assemblies. Expect precise, reproducible threads with reduced rework and longer service life compared to standard taps. The combination of cobalt-enhanced HSS and a durable Steam Oxide finish supports higher cutting speeds and reliable performance in materials like steel and cast iron, while the spiral flute design helps keep chips moving away from the thread profile for cleaner cuts and less work stoppage.
