The OSG Threading Tap RC (BSPT) with an A-Spiral flute is a precision tool designed for cutting British Standard Pipe Taper threads in blind-hole applications. Built for machinists and manufacturers who demand reliability in challenging materials, it delivers clean, accurate BSPT threads with every run.

• Thread type: BSPT (British Standard Pipe Taper) threading designed for blind-hole applications to create consistent, leak-resistant joints.
• Flute design: A-Spiral flute aids efficient chip evacuation in both through-hole and blind-hole tapping, reducing tool binding.
• Material: Powder metal construction delivering excellent wear resistance, toughness, and long tool life in demanding workpieces.
• Coating: TiCN coating lowers friction and improves heat resistance, enabling faster cutting and reduced wear during extended cycles.
• Hand: Right-hand threading, compatible with standard machining setups for BSPT components.
• Size: 3/4 x 14, providing a precise BSPT thread form for medium-to-large bore applications.
• Standards: DIN5156 compatibility ensures fittings and components mate to standard BSPT specifications.
• Application focus: Optimized for blind holes in metal parts where space is limited and reliable thread integrity is essential.

This tapping solution earns its keep in production environments by combining a robust powder-metal body with a low-friction TiCN coating and a geometry that clears chips efficiently. Expect consistently formed BSPT threads, reduced cycle times, and extended tool life even when tapping harder materials. The RC series tap is a practical choice for shops aiming to improve throughput without compromising thread accuracy or fit.
