Description
The OSG RC threading tap is a high-performance tool designed to cut British Standard Pipe Taper (BSPT) threads with precision in both through-hole and blind-hole applications. Built for durability and consistent results, it’s ideal for pipe fittings, hydraulic assemblies, and other metalworking tasks that demand reliable BSPT threading.
- Thread type: BSPT (British Standard Pipe Taper) threads for dependable pipe connections.
- Flute design: A-Straight flute for smooth chip flow, especially effective with long-chipping materials.
- Material: Powder metal body delivers enhanced wear resistance and toughness under demanding tapping conditions.
- Coating: TiCN coating reduces friction and boosts heat resistance, supporting higher cutting speeds and longer tool life.
- Direction: Right-hand threading for standard BSPT applications.
- Size: 1/4 x 19, a compact size commonly used in small-diameter fittings.
- Hole compatibility: Suitable for both through holes and blind holes (DIN5156 specification).
This combination of a durable powder-metal body, wear-resistant TiCN coating, and a straight-flute design translates to cleaner threads, reduced tool wear, and dependable performance across a range of materials and hole types. Use it to achieve consistent BSPT threads with tight tolerances, minimal burrs, and efficient chip evacuation in busy production environments.
