The OSG BA A-Spiral Point Threading Tap is designed for precise tapping of British Association threads in through holes, ideal for compact assemblies and micro-mechanical parts.

• Thread Type: BA (British Association) threads for accurate, small-diameter tapping in through holes.
• Geometry: A-Spiral Point design that actively pushes chips forward, reducing clogging and improving chip evacuation for cleaner threads.
• Material: Powder metal substrate delivering enhanced hardness, heat resistance, and wear performance in demanding tapping applications.
• Coating: TiCN coating to extend tool life and boost cutting efficiency, especially at higher speeds and tougher materials.
• Hand: Right-hand threading, standard orientation for most BA tapping tasks.
• Through-Hole Compatibility: Specifically engineered for tapping through holes to produce robust, accurate internal threads from top to bottom.
• Size: 5BA thread size for small, precision fastener applications.
• Applications: Well-suited for high-speed threading in various materials, including miniature components, instrument housings, connectors, and model-engineering projects.

Combining a specialized spiraled point with a durable powder-metal core and TiCN coating, this tap delivers reliable thread formation, efficient chip control, and longer tool life. It enables consistent, high-quality BA threads in through holes, helping you reduce rework and improve production efficiency in precision assemblies.
