The OSG BA A-Spiral Point Threading Tap is engineered for precise tapping of British Association threads in through-holes. Designed for professionals in electronics, instrumentation, and precision mechanics, it combines durable powder-metal construction with efficient chip evacuation.

• Size/Thread: 3BA BA thread tapping for through-holes in tight-tolerance assemblies.
• Design: A-Spiral Point geometry that pushes chips forward for cleaner holes and reduced clogging.
• Material: Powder-metal body delivering high strength, wear resistance, and heat tolerance.
• Coating: TiCN coating to improve cutting efficiency and extend tool life.
• Application: Right-hand threading optimized for through-holes in thin-profile parts and enclosures.
• Performance: Through-hole tapping with consistent thread quality and reduced chatter.

With this tap, you’ll experience longer tool life, faster cycle times, and reliable BA threads in challenging materials. The spiral-point design minimizes chip buildup, reducing the risk of worn threads or damaged workpieces. The TiCN coating lowers friction and heat generation, helping you cut more efficiently and achieve precise results. Ideal for manufacturing, repair, and prototyping environments where BA threading through holes is routine.
