In this video we are going to talk about the torque settings on your drill.

You need torque to drive your flexible shaft because this affects the performance of your chains

BUT, too much torque could cause damage to your flexible shaft.

A shaft can be damaged because the torque limiter on the drill is not set correctly and the flexible shaft is not lubricated.

For example if you are descaling a pipe at 1000 RPM, and the chain catches on a solid obstruction, the chain will stop instantly, and the power stored in the flexible shaft is immediately transferred from the chain through the shaft which is connected to your power drill.

If the torque limiter is set too high, the drill will spin around at 1000 RPM, and you risk the possibility of hurting yourself.

If you are holding the drill really tight, this sudden action could either kink or snap your shaft.

Set your torque limiter to the lowest possible setting as described in this video. On the drill in this demonstration, the lowest setting is number 1.

This can be confirmed by holding the drill trigger to engage the drill, and at the same time holding the rotator shaft socket in your hand so that you prevent it from turning further.

You will hear a clicking sound which is the torque limiter engaging.

Now that you know what the minimum torque limit is, you can increase the torque setting slightly until you get the chains turning nicely and do not hear the torque limiter engaging. This means that the chains are doing their job, but if they are stopped suddenly, the shaft won't be damaged.

For this drill my perfect setting is on number 4.

On the top of the drill is a gearbox setting. Setting 1 is for low speed and high torque and setting 2 is for higher speed and medium torque.

Personally I choose the lower speed and higher torque setting on the drills gearbox, but I keep my torque limiter setting low.

The reason for this is because a higher speed does not necessarily mean that the chains will perform better.

Few important things to remember:

Please be sure to lubricate your flexible shaft before the first use, 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. Our preference for lubricant is basic machine oil. Here is a video we made on how to lubricate your shaft:    • How to lubricate your flexible shaft ...  

Feel free to choose between a corded or a cordless drill, but make sure not to use the hammer action function on the drill because it can cause damage to your shaft.

With a flexible shaft you will be using less than 3% of the water you would need to get the same result with a hydro jetting machine. Imagine the amount of water you will save by using a flexible shaft.

Important note: We manufacture our own brand of shafts, and by chance our clients started adapting them to their Ridgid K102 or K204 sewer cleaning machines. They also informed us that our flexible shafts are a bit more rigid than the Ridgid flexshafts. We do not claim that we have a replacement shaft for a Ridgid Flexshaft.
