OSG's BSP Spiral Point Threading Tap is a high-performance tool designed for through-hole BSP threading. Built for machinists and production shops, it delivers clean, precise threads with extended tool life.

• Material: HSS-E (high-speed steel with cobalt) for enhanced heat resistance and durability during demanding tapping tasks.
• Coating: Steam Oxide coating that reduces wear and friction, helping the tap endure longer cycles in tougher materials.
• Geometry: Spiral point design that aggressively evacuates chips and pushes them ahead of the insert, improving cycle times and reducing chip packing in through-hole applications.
• Thread Type: BSP Spiral Point threading geometry optimized for BSP-style through-holes, delivering consistent thread formation.
• Size: 1/4 x 19, a common through-hole tapping size that supports efficient, repeatable production runs.
• Application: Specifically engineered for through-hole tapping, ideal for precision threads in metal components where reliable chip control matters.
• Brand: OSG, a trusted name in precision threading tools known for consistency and long tool life.

This tap combines robust material and a coating that stand up to repeated use, while the spiral point geometry accelerates production by keeping chips moving forward. The result is repeatable, high-quality BSP threads with reduced downtime, making it a practical choice for shops that value accuracy, efficiency, and tool longevity in through-hole projects.
