6″ to 8″ (150-200mm) Blockage Removal Kit (Cast Iron & Clay Pipes)

This drain cleaning kit is designed for blockage removal in large pipes made of cast iron and vitrified clay. Flex-shaft sewer machine like this one requires a more powerful, corded drill with a torque limiter. It includes a cutting head so it will easily remove tree roots in pipes. It will also take care of tile grout, stones and cement in pipes. Not suitable for PVC pipework.

6" to 8" (150-200mm) Blockage Removal Kit (Cast Iron & Clay Pipes)

$278.07$667.72

This blockage removal kit will not replace your high pressure water jet for the removal of sand deposits, but if you need to grind up tree roots, or remove cement, tile grout, stones and other hard blockages, then this tool will be a game changer.

The kit is not suitable for PVC because it has very aggressive metal alloy tips fused to the cutting edge. It is more suited for pipes made from cement, vitrified clay, cast iron, metal and similar hard materials.

This kit only comes with a 12mm (1/2″) shaft. Anything thinner will struggle to deliver torque demand to the chains over longer distances. You will need a more powerful drill than the smaller diameter kits, so please get in touch with us if you need a recommendation.

The X-tip chains that come with this kit are our most aggressive chains. They have a crown drill head which has a 25mm (1”) opening diameter, meant for cutting in a forward direction. They have X shaped “teeth” that rasp away whatever they come in contact with.

If you are in the pipe rehabilitation trade, you will be familiar with the challenges of extracting a failed liner. This kit will grind up a failed liner faster than chemical softeners, and you can mount a sewer camera behind the chains to see what you are doing in real time. We recommend complementing these tools with our Croco Bore for reinstatement tasks.

Lightweight and compact

The tools are lightweight and compact, so you won’t find yourself lugging a heavy machine to get to your work area. They can be transported in an elevator and give more options when dealing with blockages in high rise buildings. (You need not be concerned that you might flood someone’s apartment.)

Setting up is quick and easy because you only need to attach it to your drill, and you are ready to go.

The kit consists of:

A Flexible Shaft with Sleeve and Friction Rings

Drill to Shaft Adapter – 12mm shaft

X-Tip Chain (with drill head) DN150/6″ for 12mm (1/2″) Shaft

X-Tip Chain (with drill head) DN200/8″ for 12mm (1/2″) Shaft

Descaling

Besides blockage removal, this tool has the added advantage of descaling pipes, so you can remove lime scale build up faster and more effectively than trying to break it up with a jetting machine. This way, you will not find large broken up chunks of scale that have blocked the pipe further down the line.

Benefits to the tools

More experienced users are using a sewer cleaning camera at the same time to see what they are doing in real time because the sleeve that covers the shaft will prevent damage to the camera cable.

The sleeve is heat and chemical resistant, and protects your hands whilst handling the shaft.

This makes it safe to use in a confined space with limited access.

The shaft sleeve has friction rings to protect the ends from wear. The friction rings on each end prevent dirt from building up between the shaft and the sleeve, as this would reduce the efficiency and longevity of the tool.

Each tool is made up of three individual chains which use centrifugal force to centre the tool inside the pipe. This ensures that the entire inner diameter of the pipe is cleaned in the process.

The chains are adjustable, so it is possible to clean a wider range of pipe diameters with the same chain. To do this, you only need to increase, or decrease the space between the hubs that secure the chain to the shaft.

The chains are made from stainless steel to prevent oxidation, and are fastened to the shaft with hex screws.

Connecting your shaft with hex screws has a big advantage in that you can repair a kinked shaft quickly and easily, since you can slice off the kinked section of shaft with an angle grinder, and reconnect your shaft within minutes as opposed to replacing the whole shaft.

Before you order the longest length possible, consider this:

Most experienced users order the kit with a short shaft for everyday use; and a second shaft and connector in the van. The advantage to this is that on a day-to-day basis, you can carry around less shaft with you into your workspace. If you need extra length you can fetch your secondary shaft from your vehicle and connect it to the one you are working with.

Another advantage to having two separate shafts, is that should you accidentally kink the one you are working with, then you have a backup available immediately. No need to find your grinder to cut off the kinked section of the shaft before you can continue working.

Shaft shrinkage

When we manufacture the shafts we wind them in a long straight line. They are then wound onto a large diameter spool, and later cut into smaller pieces before we assemble them and deliver them to you. This means that when you first use your shaft, you might notice that the ends shrink a little. Usually this is more evident on the drill end.

This is perfectly normal since the shaft is subjected to the stresses of multiple bends and torque for the first time. After the first inner strands of the shaft settle into their permanent position the shrinkage will cease. Usually this affects around 3” (75mm) on either end of the shaft. When you notice this, simply cut off the shrunken section with an angle grinder, and reconnect your chains and drill. It is not necessary to weld the ends, but if you prefer to do this please try to avoid too much heat on the shaft.

Lubricate your shaft before first use

Aviation law prohibits us from delivering products which could be considered flammable so we send the shafts without lubricant in the sleeve.

Please be sure to lubricate your flexible shaft before using it, and then check the lubrication every few weeks. This not only ensures the longevity of your shaft, but also makes it more efficient over longer distances. Here is a video we made on how to lubricate your shaft:
