The OSG BSP Spiral Point Threading Tap is a high-performance tool designed for professionals who need precise BSP threads in through-hole applications. Built with HSS-E and finished with Steam Oxide, it delivers durable cutting action, reliable heat resistance, and efficient chip evacuation for demanding machining tasks.
- Threading type: BSP Spiral Point design that pushes chips forward for clean, accurate threads in through-holes.
- Material: High-Speed Steel with cobalt (HSS-E) for enhanced hardness and wear resistance during extended use.
- Coating: Steam Oxide coating reduces wear and offers improved lubricity in high-temperature cutting.
- Size: Through-hole tap sized 3/8 x 19 to match BSP threading specifications.
- Chip evacuation: Spiral point geometry facilitates efficient chip removal, minimizing clogging and rework.
- Brand technology: Leveraging OSG’s advanced threading technology for precise, high-quality thread formation and extended tool life.
Ideal for machinists and shops tackling BSP-threaded through-holes, this tap delivers consistent, accurate results with fewer passes and less downtime. The combination of HSS-E construction and Steam Oxide coating stands up to repeated use, while the spiral point design speeds cutting by directing chips away from the cutting edge. Rely on this tap for dependable performance in critical threading tasks and long-term tooling efficiency.
