Plumbers and hardware stores use the words drain auger and drain snake almost interchangeably, but there is a real difference in size, power, and what each tool is designed to clear.
The Short Answer
A drain snake (also called a hand auger or closet auger) is a short, manually operated cable — usually 5 to 25 feet long, 9mm to 12mm thick — for sinks, tubs, and toilets. A drain auger machine is a powered drum or sectional unit with a motor, auto-feed, and 50 to 200 feet of 16mm to 28mm cable for floor drains, main sewer lines, and commercial stacks.
Side-by-Side Comparison
- Drain snake / hand auger: 9-12mm cable, 5-25 ft, manual crank, clears hair and toothpaste, cost $30-$150.
- Closet auger: short rigid tube, 1/2 inch tip, specifically for toilets to avoid scratching the bowl, cost $20-$60.
- Electric drain auger machine: 16-22mm cable, 50-100 ft, 250-750W motor, auto-feed, clears grease and roots in 2-6 inch lines, cost $300-$2,500.
- Sectional drain machine: 16-28mm loose sections, 75-200 ft reach, navigates multiple bends, used by pro plumbers, cost $1,200-$4,000.
When to Use Which
- Sink or bathroom clog: hand drain snake is enough.
- Toilet clog: closet auger (not a sharp drum machine tip).
- Kitchen drain or floor drain backing up: 16mm electric drain auger machine.
- Main sewer line (4-6 inch): 22mm sectional or drum machine, 100 ft+ cable.
- Commercial building or restaurant grease trap: 22mm drum machine or a 3,000-4,000 PSI water jetter.
What Do Professional Plumbers Carry?
Most service vans carry both: a closet auger for quick toilet calls, and a 16mm sectional machine or 22mm drum machine for main lines. Brand names like Ridgid, Spartan, and THAIMAKE OEM units all fall into this category — the difference is mostly build quality, cable type, and ETL/cUL certification for the North American market.
FAQ
Is a drain snake the same as a drain auger?
Not exactly. A drain snake usually means a short hand-operated tool. A drain auger usually means either the same hand tool or a powered machine. When a buyer says drain auger machine they mean the electric sectional or drum unit.
What size drain auger do I need for a main line?
For a 4-6 inch main sewer line, use a 22mm drum machine with 75-100 ft of cable. For 6+ inch commercial lines, step up to 28mm cable or a water jetter.
Can I use a drain snake on a toilet?
Use a closet auger, not a standard drum machine. A closet auger has a protective rubber sleeve and a short rigid tube that won’t scratch the porcelain.
How much does an electric drain auger machine cost?
Entry-level 16mm electric machines start around $300. Commercial 22mm drum machines cost $1,200-$3,500. A 22mm sectional machine for pros runs $1,500-$4,000.
Does THAIMAKE make both drain snakes and auger machines?
THAIMAKE manufactures manual toilet augers, electric sectional machines, compact drum machines, and high-pressure water jetters at its 6,000 m² factory in Chonburi, Thailand. All electric models are ETL Listed for the North American market, with OEM/ODM and private label available to distributors.
