High-Speed Cable Kinking

“I bought a high-speed cable that I attached to my drill, but I keep kinking the cable. It usually kinks either right by the drill or at the other end by the tool I’ve attached. Am I doing something wrong or did I get a bad cable?”

Using a high-speed cable is much different than using a standard cable machine in that the speed becomes a factor in the forces on the cable that you don’t experience with a conventional cable machine that turns at 250 to 300 rpm’s. Your drill can drive the high-speed cable at speeds up to 3000 rpm’s so the relationship of speed to torque is much different than you find in a conventional cable. You use these cables a little differently than the conventional machine.

A good comparison would be to imagine a hand saw cutting through a 2 x 4 vs. a powered circular saw cutting through the same 2 x 4. A hand saw works by exerting force (your hand) to the saw pushing on the 2 x 4. When using a power saw you let the blade perform the work and provide gentle pressure to move the saw through the wood. Pushing the powered saw can cause it to bind and stop. If you think of using these two tools similarly you have a better concept of how each works.

We’ve also found that placing short sections of pex tubing over the areas of exposed bare high-speed cable will support the cable and minimize the kinking issue. That method and not putting too much pressure on the tools as it works its way through the obstruction will keep your cable running a long time.
