Expertly engineered for high-precision manual threading operations in demanding hydraulic, pneumatic, and fluid-handling environments, the Somta BSPT Straight Flute Bottoming Hand Tap range is the definitive industrial choice for cutting British Standard Pipe Taper profiles. Operating on the standard 55° Whitworth form with an exact 1:16 thread taper, these premium high-speed steel (HSS-E) tools feature a robust straight flute geometry and a reinforced square drive shank optimized for manual tap wrenches. The precision-ground bottoming lead profile utilizes a short 1-to-2 thread chamfer, allowing machinists to cut fully formed, pressure-tight pipe threads right down to the base of closed pockets, blind manifolds, and heavy castings. Engineered by Somta to handle intense manual torque with zero tool deflection, this heavy-duty pipe tap series is structurally optimized to deliver exceptional tool life and perfect pitch compliance across structural steels, mild steel, AS/NZS 3678 250 and 350 grade plate, free-cutting steels, and unalloyed case-hardened steels.
