4″ to 6″ (100-150mm) Drain Descaling Kit

Flexible drain cleaning shaft with a protective sleeve and circular sewer cleaning chains are all included in this pipe cleaning kit meant for descaling PVC or Cast iron and clay pipes. This sewer cleaning kit will eliminate tree root intrusion, cement, tuberculation, tile grout, limescale and urine scale in pipes. Unlike sewer chain knockers, circular chains work on the entire inner circumference of the pipe.

4" to 6" (100-150mm) 4" to 6" (100-150mm) Drain Descaling Kit (PVC Pipes)

$186.93$600.72

This kit is designed for descaling PVC or Cast iron and clay pipes with a diameter of 4 and 6 inches. (100mm-150mm)

Perfect for the quick and effective removal of hard incrustations such as urine scale, limescale, cement, or even tile grout.

The circular chains that come with this kit are suitable for removing soft blockages, but these chains have more links on the pipe wall at any given moment than a conventional drain cleaning chain. This gives them an advantage for descaling tasks.

In contrast to the conventional drain cleaning chains, the circular chain also prevents the pipe wall from being subjected to individual blows because the chain works over the full inner circumference of the pipe.

Depending on your selection, the chains can either have tungsten carbide bits fused to the cutting edge, or in the case of PVC pipes the chains will be plain chains (without tungsten carbide bits) This prevents damage to the pipe wall of PVC pipes. If you choose “both PVC and cast iron pipes”, then we will supply the kit with all of the chains ( 1 x 3″ with bits, 1 x 3″ without bits, 1 x 4″ with bits and 1 x 4″ without bits)

The tool is lightweight and compact, so you won’t find yourself lugging a heavy machine to get to your work area. Setting up is quick and easy because you only need to attach it to your drill, and you are ready to go.

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. All you need to do is slice off the kinked section of shaft with an angle grinder, and reconnect your shaft within minutes as opposed to replacing the whole shaft.

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. This ensures maximum performance because the drill does not need to work against dirt in the sleeve and turn the chains.

The drain descaling kit includes:

  • Flexible Shaft with Sleeve and Friction Rings
  • Drill to Shaft Adapter
  • Circular Chain DN100mm (4″) – (depending on your selection the chains will either have tungsten carbide bits or not)
  • Circular Chain DN150 mm (6″)- (depending on your selection the chains will either have tungsten carbide bits or not)
  • Shaft carrier (if selected)

Before you order the longest length possible, consider this:

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

Another advantage to having two separate shafts, is that should you accidentally kink the shaft 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.

Which shaft thickness should you choose?

The thickness of the shaft depends on the amount of bends that you would like to pass through. The more bends you need to get through, the thinner the shaft should be. However, the thinner the shaft is, the less torque the shaft delivers.

The 8mm (5/16”) flexible shaft is our second most flexible shaft. It has the ability to pass through multiple bends, and has more torque than the 6mm (¼). This shaft is most suitable for pipes with a diameter of 75mm (3”) to 100mm (4”), and will work with blockage removal chains as well as descaling chains.

The 10mm (3/8″) flexible shaft is less flexible than the 8mm (5/16) shaft, and yet more flexible than the 12mm (½”). This shaft will navigate through fewer bends than the 8mm (5/16) shaft, but will offer the user similar torque to the 12mm (1/2″). This shaft is suitable for pipes ranging from 75mm (3”) to 150mm (6”).

The 12mm (½”) flexible shaft is our most rigid shaft. This shaft is popular for failed liner removal since it offers the highest torque ratio. The shaft is perfect for descaling and blockage removal of lines ranging from 100mm (4”) to 250mm (10”)

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 cut into smaller pieces before we assemble them to deliver 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. On average you will need around 15 to 20 milliliters of lubricant per meter (about 0.23 oz per foot).

Here is a video we made on how to lubricate your shaft:
