The OSG BA Spiral Flute Threading Tap is a precision tool designed to cut British Association (BA) threads in blind holes, making it ideal for electronics, instrumentation, and precision assemblies. With a TiCN-coated powder-metal body and spiral flute geometry, this tap delivers dependable threading performance and extended tool life.

• Thread type: BA (British Association) thread size, specifically 10BA
• Flute geometry: Spiral flute for efficient chip evacuation in blind holes
• Material: Powder-metal substrate for durability, wear resistance, and toughness
• Coating: TiCN (Titanium Carbonitride) coating to reduce friction and improve heat resistance
• Direction: Right-hand threading for standard BA tapping
• Application: Designed for cutting threads in blind holes with clean, accurate profiles

This tap’s spiral design minimizes chip buildup, reducing the risk of binding and breakage when tapping in confined blind-hole environments. The powder-metal construction balances hardness with toughness, helping it withstand repetitive tapping cycles without losing sharpness. The TiCN coating further extends life by lowering friction and improving heat resistance, enabling more consistent performance at higher speeds and feeds. Together, these features deliver reliable, repeatable BA threads with tight tolerances and a smooth finish.
