The OSG BA Spiral Point Threading Tap in 3BA is a precision threading tool built for through-hole applications. Designed for machinists and electronics-mechanics who require dependable, accurate BA threads in small parts, it delivers clean, consistent results with every pass.

• Material & coating: HSS‑E (high-speed steel with cobalt) for enhanced strength and wear resistance, finished with a steam oxide coating to improve heat resistance and reduce galling.
• Threading geometry: Spiral‑point design that pushes chips forward and guides the tap into the hole, promoting smooth, straight thread formation in through-hole work.
• Size & compatibility: 3BA through-hole tapping tap, ideal for compact BA-threaded components, enclosures, and precision assemblies.
• Durability: Cobalt alloying and the oxide finish extend tool life in demanding tapping tasks and high-speed operations.
• Application focus: Specifically optimized for through-hole tapping where fast cycle times and reliable thread depth are critical.

This tap helps you achieve reliable, repeatable 3BA threads in small parts, reducing rework and downtime. The spiral point design enhances chip evacuation, minimizing clogging and cross-threading risks, while the HSS‑E composition and steam oxide coating deliver consistent performance across batches. Ideal for instrument housings, compact assemblies, and other precision components that rely on durable, accurately sized BA threads.
