About the Replacement Carbide Insert
This is the replacement carbide insert for the Single Flute Insert Fly Cutter. Though not inexpensive, when you consider you are getting two 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.
NOTE: Replacement carbide inserts for other inserted tip tools are available through Sherline. See our page on carbide tools.
