OSG's BSW Spiral Point Threading Tap is engineered for precise, reliable through-hole threading with 1/2-12 BSW threads. Designed for machinists who demand consistent results, it combines durable materials and advanced geometry to support high-volume or critical-tolerance tapping tasks.

• Size & Thread: 1/2 x 12 BSW through-hole threading tap for standard through-hole applications.
• Material: HSS-E (high-speed steel with cobalt) for enhanced hardness and heat resistance during demanding cuts.
• Coating: Steam Oxide coating provides wear resistance and aids in longer tool life.
• Flute/Point Geometry: Spiral Point design delivers efficient chip evacuation, reducing clogging in through-holes.
• Brand & Series: OSG BSW Spiral Point Threading Tap, backed by OSG’s precision threading technology.
• Application: Ideal for through-hole tapping where clean, accurate threading is essential in BSW standards.

This tap helps you produce precise threads with reduced rework and longer tool life. The cobalt-enriched steel and steam oxide coating work together to withstand heat and wear, while the spiral point geometry minimizes chip buildup and downtime. A reliable choice for production runs and critical assemblies that require consistent, high-quality threads.
