- Material: HSS-E (high-speed steel with cobalt) for enhanced hardness and wear resistance under cutting conditions
- Coating: Steam Oxide finish that boosts durability and provides improved lubricity during tapping
- Thread design: BSP spiral point geometry to efficiently form threads and evacuate chips from through holes
- Size: 1/8 x 28 BSP threading for precise, consistent results
- Application: Specifically engineered for through-hole tapping tasks requiring reliable BSP threads
OSG’s advanced threading technology helps you achieve precise, high-quality BSP threads with extended tool life, even in demanding machining scenarios. The spiral point design minimizes chip buildup and push-out pressure, keeping cuts smooth and predictable across multiple productions runs. This tap is ideal for engineers and machinists who value consistent performance, reduced downtime, and threaded joints that meet exacting standards in metal fabrication.
