Engineered for durable, precise BSF threading in through-holes, the OSG BSF A-Spiral Point Tap is the go-to tool for professionals who demand reliability in British Standard Fine threads. Built for high-speed tapping in demanding materials, it combines a powder metal body with a TiCN coating to extend tool life and maintain cutting performance.

• Thread Type: British Standard Fine (BSF)
• Size x Pitch: 7/16 in, 18 TPI
• Point Style: A-Spiral Point designed to push chips forward for smooth tapping
• Material: Powder Metal construction for enhanced strength and wear resistance
• Coating: TiCN coating to reduce friction and improve wear life
• Through-Hole Design: DIN2184-1 compliant for tapping through-holes
• Drive: Right-Hand thread for standard tapping applications

This tap delivers cleaner, more consistent threads by directing chips ahead of the cutting edge, minimizing clogging and downtime. The TiCN coating boosts cutting performance at higher speeds while resisting heat and wear, making it suitable for a wide range of metals encountered in both maintenance and production environments. The powder metal body further contributes to durability and long-term reliability, helping shops meet tight tolerances on BSF through-holes without frequent tool changes.
