The OSG BA Spiral Point Threading Tap in 1BA is built for precision tapping in through-hole applications, delivering accurate BA threads with reliable durability. Crafted from HSS-E cobalt steel and finished with a steam oxide coating, it’s designed to withstand heat and wear in demanding metalworking tasks.

• Size: 1BA threading tap, optimized for through-hole BA threads.
• Material: HSS-E (high-speed steel with cobalt) for improved hardness and wear resistance.
• Coating: Steam oxide coating enhances corrosion resistance and reduces friction during cutting.
• Geometry: Spiral point design that aids chip evacuation and minimizes threading resistance in through holes.
• Application: Ideal for through-hole tapping on metal components, delivering clean and accurate threads.
• Brand: OSG threading solutions known for consistency and extended tool life.

This tap helps you achieve dependable BA threads with reduced tool wear and fewer rework cycles. The cobalt-infused HSS-E core stays sharper longer under heat, while the spiral point geometry and steam oxide coating work together to deliver smooth cuts, efficient chip control, and a high-quality thread finish in through-hole work. Perfect for precision instrument housings, small assemblies, and applications where exact BA threading is critical.
