The OSG G (BSP) A-Spiral Point threading tap is engineered for precise G-type (BSP) threads in through-hole applications. It’s designed for machinists and shops that value durability, accuracy, and efficient chip control in metalworking.
- Thread type: G (BSP) right-hand threads, crafted for standard pipe-fitting specifications and reliable field performance.
- A-Spiral Point geometry: Spiral point design facilitates efficient chip evacuation in through-holes, reducing binding and improving thread quality.
- Material: Powder metal construction delivers excellent strength, wear resistance, and heat tolerance for demanding cutting conditions.
- Coating: TiCN coating lowers friction, boosts tool life, and enhances cutting efficiency across multiple materials.
- Size: 7/8" nominal diameter with 14 threads per inch (7/8 x 14), suitable for through-hole BSP threading.
- Right-hand tap: Conventional right-hand threading profile for standard assembly and replacement tasks.
- DIN standard: DIN5156-compliant profile to ensure compatibility with common G BSP components and tooling ecosystems.
- Through-hole suitability: Specifically optimized for through-hole work, enabling full thread engagement and repeatable results.
This tap helps you achieve clean, accurate G BSP threads with outstanding wear resistance and long tool life. The TiCN coating reduces heat buildup during high-speed machining, while the A-Spiral Point design keeps chips moving forward, minimizing rethreading or tool fouling. Ideal for hydraulic, pneumatic, and general pipe-fitting components where reliable BSP threading and consistent performance matter, this tap supports high-precision work, reduced downtime, and repeatable results across a range of materials.
