Many of these blades are made with carbide grit or diamond grit for cutting through hard items.
 Mark the lines as straight as possible. Hold the pipe firmly in place. It may be easier to have another person hold it in place for you.
 Avoid applying undue pressure on the saw that can cause the blade to snap.
Fit your saw with a long metal cutting blade.
Use chalk to mark your cut lines.
Set your saw at low speed and let the blade do the work for you.
