Choosing a drain cleaning tool comes down to a few questions: what size line are you clearing, how long is the run, and what is blocking it? A clogged toilet and a root-choked sewer main call for completely different equipment. RIDGID makes drain cleaning tools for every job in between — sinks, toilets, floor drains, sewer lines, grease buildup, and root intrusions — from lightweight hand augers for everyday service calls to heavy-duty machines for tough main line obstructions, all backed by RIDGID for a lifetime. This guide explains what each type does best and how to match the right one to the job.
Each type at a glance
Hand tools
Hand tools are the first line of defense for fixture clogs — no power required, though some accept a drill for extra torque:
- K-3 and K-6 toilet augers — available in 3' and 6' lengths for clearing toilet clogs, with a vinyl guard to protect the porcelain. The K-6P extends the cable 6 feet beyond the toilet and accepts an optional drill attachment for up to 500 RPM, and the drop head version of the K-6 helps navigate back-to-back plumbing fixtures.
- K-1 Combination Auger — clears urinals and shower drains up to 2" with a telescoping 3/8" x 4' inner core cable and a "C" cutter for hard blockages. It works by hand or with an optional drill attachment up to 500 RPM.
- Hand spinners, sewer tapes, and grappler hooks — compact manual tools that round out RIDGID's hand tool lineup for small lines and quick service calls.

Sink machines
Sink machines are compact, portable tools for the small-diameter lines that clog most often:
- PowerClear — a lightweight drain cleaner for tub, shower, and sink blockages from 3/4" to 1-1/2". Its compact design makes it easy to work in tight spaces like under a sink.
- K-45 — a sink machine with interchangeable inner drums for quick cable changes. RIDGID rates its 1/4" cables for 3/4" to 2" lines, 5/16" cables for 3/4" to 2-1/2" lines, and 3/8" cables for 1-1/4" to 3" lines.
- K-46 Cordless SinkSnake — a cordless option on RIDGID's 18V platform. Learn more in our K-46 guide.

Drum machines
Drum machines store the cable inside a rotating drum, which keeps the work area cleaner and makes the cable easier to feed and retrieve. The lineup scales from everyday drain lines up to larger lines:
- K-400 — built for everyday blockages in tubs, showers, and sinks, cleaning 1-1/2" to 4" drain lines. RIDGID notes the K-400 is not designed to remove root blockages.
- Larger drum machines — the K-750, K-750R, K-3800, and K-7500 step up for larger, longer lines. Line capacity depends on the model and cable, so check each machine's specifications.

Sectional machines
Sectional machines use short cable sections that are connected together on the job, so the machine stays light and the cable length can be matched to the run. They are the go-to choice for long runs and larger lines.
- K-50 — a compact all-around sink, shower, and floor drain machine that weighs less than 40 lbs. It runs three cable sizes, and with 5/8" sections it cleans 1-1/4" to 4" lines up to 100 feet.
- K-60SP — a larger sectional machine in RIDGID's lineup for bigger lines.
- K-1500 — RIDGID's all-around sewer and drain machine for 2" to 8" lines.
- K-1500SP — runs 1-1/4" cable sections to clean 3" to 10" lines up to 300 feet, or 7/8" sections for 2" to 4" lines up to 175 feet.

Water jetters
Water jetters use high-pressure water instead of a cable to clean drain lines, making them a strong option for tough blockages and ongoing pipe maintenance. RIDGID's lineup includes the KJ-1350, KJ-1750, KJ-2200, and KJ-3100 series. Capacity and pressure vary by model.

FlexShaft machines
FlexShaft machines use a spinning shaft with a chain knocker to clean pipe walls from side to side, rather than just punching a hole through a blockage. RIDGID's FlexShaft lineup covers 1-1/4" to 6" lines up to 125 feet and includes the K9-12, K9-102+, K9-204+, and K9-306.
For heavier pipe rehab work, the KM-1004 FlexShaft Milling Machine combines drain cleaning and milling in one machine, built to remove scale, corrosion, grease, and roots in 1-1/4" to 4" lines.

Cables and tools
Every machine is only as good as the cable and cutting tool on the end of it. RIDGID makes replacement drain cables sized for each machine and line, along with cutting tools for different blockages — straight and funnel augers, 4-blade cutters, grease cutters, chain knockers, and more. Matching the cable and cutter to both the machine and the line size is key to clearing blockages efficiently.

Matching the tool to the job: start with the fixture and line size, then consider the run length and the blockage. Toilets and urinals start with a hand auger. Small fixture lines call for a sink machine. Everyday drain lines fit a drum machine like the K-400 — which is not designed for roots. Long runs, larger lines, and roots point to a sectional machine. For cleaning pipe walls rather than just opening a clog, look at FlexShaft. And always match the cable size to the line, following RIDGID's recommendations for each machine.
Frequently asked questions
What is the difference between a drum machine and a sectional machine?
A drum machine stores one continuous cable inside a rotating drum. A sectional machine uses short cable sections that connect together, which keeps the machine lighter and lets you match the cable length to the run.
Which RIDGID machine handles the largest lines?
Among the machines covered here, the K-1500SP cleans the widest range — 3" to 10" lines up to 300 feet with 1-1/4" cable.
Can a K-400 clear roots?
No. RIDGID notes the K-400 is not designed to remove root blockages.
What is a FlexShaft machine used for?
FlexShaft machines clean pipe walls from side to side, which makes them well suited to restoring flow rather than just opening a single clog.
What warranty do RIDGID drain cleaning tools have?
RIDGID backs its drain cleaning tools for a lifetime. See RIDGID's warranty terms for details on specific products.
