Model 1224 Threading Machine


  • The Model 1224 threads a wide range of pipe including black, galvanized and plastic-coated pipe, together with stainless steel, IMC and heavy-wall conduit, as well as rod up to 30 Rockwell C.
  • An induction motor helps minimize noise.
  • A special capacitor-start / capacitor-run motor allows the 1224 to thread a full range of material where voltage drop is experienced.
  • 1/4"-2" Universal Die Head; 2 1/2"-4" receding die head allows cutting of tapered or straight NPT/NPSM or BSPT/BSPP threads.
  • Constant and proper lubrication of dies and workpiece with through-head oiling.
