Though not inexpensive, when you consider you are getting four cutting tools in one and are saving a lot of time in tool sharpening, it is really a pretty good deal.
Carbide cutters give good finishes on hard-to-machine materials such as cold rolled steel. They will also work on aluminum, brass or leaded steels, and will last practically forever, however, the best finishes on those materials are still achieved with a good, sharp high-speed steel tool.
