The Tanoi (G) BSP Tap with an oxide finish is a precision threading tool designed for British Standard Pipe connections. Sized for 1/4x19 BSP threads, it delivers clean, reliable BSP threading across a wide range of materials—making it a dependable choice for both professionals and serious hobbyists.

• Model / Series: 570, V3 edition for proven performance and consistency
• Thread Standard: British Standard Pipe (BSP) spiral-flute tap optimized for 1/4" x 19 TPI connections
• Material: HSS-E (high-speed steel with cobalt) for improved toughness and heat resistance
• Flute Design: Spiral flute facilitates efficient chip evacuation and reduces the risk of jamming during depth threading
• Finish: Oxide coating to enhance wear resistance and extend tool life in challenging materials
• Ideal Use: Suitable for most materials and high-speed threading applications, from metalworking to plumbing-related projects

The spiral-flute geometry paired with cobalt-enhanced HSS delivers precise, consistent threads with minimal work hardening, even in tougher metals. The oxide finish reduces friction and heat buildup, helping maintain sharp cutting edges for longer runs between resharpening. With its 1/4x19 BSP specification, this tap ensures reliable mating with standard BSP fittings, making it an excellent choice for creating durable, leak-tight threaded joints in plumbing, pneumatic, and hydraulic assemblies. Whether you’re outfitting a professional workshop or tackling a home project, this Tanoi BSP tap is engineered to deliver steady performance, repeatable results, and lasting value.
