A Guide to Drain Cleaning Cable Machines

Drain cleaning cable tools and machines use rotational power that is transferred along a flexible, spiral-shaped cable to the cutting tool at the head.  

Cable tools and machines are available in a wide range of configurations, including simple hand-operated tools, drill-driven power tools, and larger units with independent electric motors. Powered machines have the advantage of variable speed, which offers greater control and less risk of pipe damage. In recent times, high-speed flexible shaft machines have grown in popularity due to their enhanced cleaning capabilities and are becoming a must-have tool for drainage contractors and plumbers.

Wire-wound cables are sized to suit the pipe diameter and have the flexibility to pass through bends while offering the strength and stability to tackle obstructions and residue build-ups in the pipe. Cables can be used with a multitude of cutting heads, from simple tools such as the straight or funnel augers, through cutting and blade heads to carbide-tipped milling cutters and drill heads.

1. HIGH-SPEED FLEXIBLE-SHAFT MACHINES

High-speed flexible shaft technology is relatively new to the sector but has seen rapid growth in use.

The torsional strength of the flexible shaft when rotated at speeds up to 3,000 rpm makes these types of drain cable machines a powerful option for wall-to-wall pipe cleaning. Powered either by a small electric motor or hand drill, flexible shaft cutters are ideal for the rapid removal of rust, cement, lime and small tree roots in domestic drains and sewers.

The sharp cleaning head at the leading end of the cable is sized to the diameter of the pipe being treated, making it useful for applications such as CIPP preparation and scale removal. With the correct cutting heads, flexible shaft cleaners can be used in different pipe materials such as concrete, cast iron and PVC. This is further enhanced by the ability to control the speed and torque of the cutter, reducing the risk of pipe damage and improving the effectiveness of the clean.

1. WALL-TO-WALL CLEANING

The flexibility and strength of the shaft allows easy access to tight, twisting pipe runs. A wide range of chain heads or knockers can be used in different drain types and diameters, with carbide tip heads suitable for cast iron and concrete pipes and smooth chain heads for PVC pipes. There are also drill heads available for the toughest jobs.

2. EASE OF USE + TRANSPORT

Typically compact and lightweight, these units often include wheels for ease of transportation. In some cases, the electric engine pack and the reel can be separated and used independently. The spring is protected with a flexible cover that aids navigation through the tightest of bends and is easy to clean.

3. RADIO REMOTE CONTROL

Typically compact and lightweight, these units often include wheels for ease of transportation. In some cases, the electric engine pack and the reel can be separated and used independently. The spring is protected with a flexible cover that aids navigation through the tightest of bends and is easy to clean.

4. MACHINES CAN BE USED WITH CCTV

As flexible shafts cleaners are water-free they can be used in conjunction with a drain camera system. The outer covering on the shaft protects the camera from damage and allows the operator to view the pipe as it is being cleaned. The camera is fed into the drain just behind the spinning end of the cable.

2. DRUM + SECTIONAL MACHINES

Cable machines operate using variable speed to spin, scour and cut as the cables are fed into a drain.

Drain cable machines are also commonly known as ‘spring machines’ or ‘drain snakes’ and range in size and features based on the type of cleaning task. The two main types of cable machines are drum and sectional, or suitcase, designs. Both utilise flexible cable lengths with a range of cleaning and cutting heads. In simple terms, a drum machine contains the entire length of cable in its housing (the drum), whereas sectional machines use coupled sections of cable that are transported separately. Both types have advantages. Enclosed drain drum machines are cleaner for internal work and easily transportable. Sectional machines are lightweight and capable of longer runs, with operators only needing to transport the length of cable that is required for a specific task.

As drain cleaning technology has advanced machines have become lighter, more powerful and safer to use. The variety of scouring cables and cutting blades has also evolved to allow the machines to tackle a wide range of drain cleaning applications.
