The OSG BA Spiral Flute Threading Tap is engineered to cut British Association (BA) threads in blind holes with dependable accuracy. Designed for the compact 5BA size, this right-hand tap uses a TiCN-coated, powder-metal core to deliver durable performance in demanding tapping tasks.

• Size & thread type: 5BA British Association thread, right-hand orientation for standard blind-hole tapping
• Material: Powder metal substrate for enhanced hardness, wear resistance, and heat tolerance
• Coating: TiCN (Titanium Carbonitride) coating reduces friction and extends tool life
• Flute geometry: Spiral flute design promotes efficient chip evacuation in blind holes and helps maintain thread quality
• Application: Optimized for tapping BA threads in blind holes within metalwork and compact assemblies

With its combination of robust material, friction-reducing coating, and chips-friendly flute geometry, this tap supports clean, precise thread formation and longer tool life. The spiral flute aids in consistent cutting in confined depths, while the TiCN coating enables reliable performance at higher speeds without sacrificing thread accuracy—making it a dependable choice for small-diameter BA threading work.
