The BA Spiral Flute Threading Tap from OSG is engineered for precise BA-threading in blind holes, delivering reliable, high-quality internal threads in compact components. Designed for professional workshops and precision assemblies, it combines durability with efficient chip evacuation for smooth tapping in restricted spaces.

• Thread Type: BA (British Association) threads for accurate, consistent internal threading in small parts.
• Size: 3BA, a compact size ideal for micro-precision applications.
• Material: Powder metal construction that offers enhanced hardness, wear resistance, and durability under tapping loads.
• Coating: TiCN (Titanium Carbonitride) coating reduces friction, improves heat resistance, and extends tool life for higher-speed tapping.
• Flute Geometry: Spiral flute design enables efficient chip evacuation, reducing clogging in blind holes.
• Direction: Right-hand (clockwise) threading for standard tapping operations.
• Hole Type: Optimized for blind holes where access is limited and chip removal is critical.

With this tap, users can achieve clean, precise BA threads in blind holes with dependable repeatability. The combination of powder metal substrate and TiCN coating minimizes wear and heat buildup, allowing for steadier cutting conditions and longer tool life. The spiral flute ensures chips exit smoothly, reducing the risk of jamming and guaranteeing consistent thread formation in tight spaces. Ideal for small mechanical assemblies, precision instrumentation, and electronics enclosures where compact, reliable internal threading matters.
