Expertly engineered for high-precision manual threading operations in demanding hydraulic, marine, and fluid-power environments, the Somta BSP/BSPP Straight Flute Bottoming Hand Tap range is the definitive industrial choice for cutting British Standard Pipe parallel profiles. Operating on the standard 55° Whitworth parallel form (often classified interchangeably as G-series or BSPP), these premium high-speed steel (HSS-E) tools feature a robust straight flute geometry and a reinforced square drive shank optimized for secure manual wrench engagement. The precision-ground bottoming lead profile features a short 1-to-2 thread chamfer, allowing machinists to cut fully formed, parallel pipe threads down to the absolute base of blind pockets, valve manifolds, and closed port castings. Engineered by Somta to handle intense manual torque with maximum structural rigidity, this heavy-duty parallel pipe tap series is optimized to deliver exceptional tool life and perfect pitch compliance when threading structural steels, mild steel, AS/NZS 3678 250 and 350 grade plate, free-cutting steels, and unalloyed case-hardened steels.
