The ends are correct and this 75 ft drain cable fits inside the drum of the HF power feed drain machine. However, the tool connector end of the cable has a 1/4-20 screw for attaching the cutters....if you have been using a longer machine screw to be able to have a "safety nut" on the cutter attachment, you will have to buy the correct size screws. Also, while the HF drum has the capacity to hold the full 75 ft, and it has enough power to advance the full length down the sewer lateral, the HF machine lacks the power to pull the longer (thus heavier) cable back into the drum....I had to assist in pulling the cable back out of the sewer. Also, plan on applying more force on the screw that "grips" the cable to advance/retract. Also, as long as you are working on the machine, you may as well add anti-seize grease in that feed/reverse clutch to all the surfaces where moving aluminum and steel parts interface. I also took the time to modify the mount on that feed/reverse clutch, as it came from HF misaligned with the cable drum.
