I need to cut some metal fence, and I don't have a reciprocal saw. I've included a picture of the fence to give you an idea of its thickness. Essentially, I'll be cutting the rail off the post. The area where I want to cut is approximately 1"x2".

Is there something for the drill that can replace the reciprocal saw for this type of job?

Thanks.
