Expertly engineered for high-efficiency parallel pipe threading, the Guhring BSP / BSPP Spiral Point Gun Tap range is the definitive industrial choice for high-speed automated machine tapping in straight-through clearance holes. Operating on the standard 55° British Whitworth thread profile, these premium parallel pipe taps feature a specialized angular spiral point geometry that shears the material cleanly and drives the metal chips forward, shooting them ahead of the tool. This advanced mechanism completely eliminates the risk of chip nesting, micro-chatter, and catastrophic tool binding around the shank. Manufactured from a premium high-speed steel substrate with advanced surface treatments for optimal lubrication retention, this series ensures perfect pitch compliance and extended tool life when high-speed threading structural steels, fluid manifolds, hydraulic block plates, and tough stainless steel components.
