What's So Good About High Speed Steel?

At the speeds and feeds that most of us home shop machinists use, high speed steel will provide a better surface finish than carbide inserts. In other words, you can do better work with high speed steel.

For roughing cuts, use carbide. For finish cuts, use high speed steel. Because these tools are indexable, you can simply change the insert, and resume cutting at the same tool position.

The picture below shows two pieces of steel. In each case, the left part of the turned area was done with a carbide insert. The right part was done with a high speed steel insert.

The bottom bar is cold finished steel from a hardware store. This is one of the most difficult materials on which to get a good finish. The difference in finish between the two sides is quite apparent.

The top bar is 12L14 steel. This is one of the easiest materials on which to get a good finish. The difference is not a marked, but is visible.
