The Somta Series 907 Bottom Tap is a precision-manufactured 1/2" BSPF (British Standard Pipe Parallel) hand tap designed for cutting or cleaning internal parallel pipe threads close to the bottom of blind holes. Manufactured from premium Carbon Steel (Zone 5) to BS 949:1951 standards, this bottoming tap is intended for thread finishing after the taper and second taps have been used, producing full-depth threads as close as possible to the bottom of the hole.

Featuring a 55° Whitworth thread form, 14 TPI, straight flutes, and a right-hand cutting action, the tap offers excellent alignment and chip control when hand tapping mild steel, brass, aluminium, cast iron, and other general engineering materials. It is ideal for maintenance workshops, plumbing applications, repair work, and general engineering where accurate BSP parallel threads are required.
