The OSG BSW Spiral Point Threading Tap is a precision through-hole threading tool designed for metalworking professionals who demand consistent, high-quality BSW threads. Built from HSS-E (high-speed steel with cobalt) and finished with a Steam Oxide coating, it delivers outstanding durability and heat resistance for demanding machining tasks.

• Thread Form: Spiral Point design engineered for efficient chip evacuation in through-holes, delivering clean, accurate threads.
• Material: HSS-E (high-speed steel with cobalt) for enhanced hardness and wear resistance at higher cutting temperatures.
• Coating: Steam Oxide coating boosts wear and heat resistance, helping extend tool life in tough materials.
• Size: 5/32" diameter with 32 threads per inch (5/32 x 32) for standard BSW through-hole applications.
• Application: Optimized specifically for through-hole tapping, delivering reliable performance in a range of metals.

This tap is designed to produce precise, durable threads with minimal tool wear. The cobalt-infused substrate and oxide finish help maintain thread accuracy under repetitive cutting, while the spiral point actively pushes chips out of the hole, reducing snagging and improving cycle efficiency. Ideal for production settings and professional workshops where consistent thread quality and extended tool life matter most.
