Sets include auger heads and cutters that fit specific drain cleaning guns, augers, or machines. Auger heads and cutters attach to a compatible drain cable and provide the point of contact to clear blockages. Also called drain cleaning tools, they have different designs to clear different types of blockages. Augers heads are spring tools that push into blockages. Cutters are bladed or toothed tools that pierce, slice, or chop into blockages.
