Cutting out the rust, cuttoff tool? Options

[swl]

I bought myself a compressor and el cheap tool kit. I was kind of hoping that the cutoff tool would be the right thing for cutting out the cancer. Had a go at it today but this tool was useless. No torque at all - stalled with very little pressure - hardly any sparks. There is an adjuster on it that seems to throttle the air supply. Played with that a bit but it didn't really make any difference.

So do I have a faulty tool or just the wrong tool for the job?

Cutoff tools and grinders need a LOT of air. You need a serious compressor to drive them. Look at CFM ratings, they're the most important when dealing with tools like this. With my compressor, I can run the tool for maybe an inch or two cutting sheet before I have to pause and wait for the compressor to refill the tank.

A Dremel works well for some areas. Buy the fiber reinforced cutoff wheels. You go through them fast, but the cut is quick and smooth. The brown-colored cutoff wheels are pretty useless for cutting steel. They break apart way too easily.
