There are different types of turning tool which divided by their structure. They are integral turning tool, welding turning tool, machine clamped turning tool, index able turning tool and molding turning tool. Among them, the application of index able turning tool is getting more and more popular with people, with four cutting edges are available, no matter in the factory or in personal workshop, you can always see them. And its users are still increasing.
Except tools themselves, the blade which loaded on them is also very important. Different shapes of blades decided what they can be used for. For example, square blades can be used to do the rough processing and diamond shaped blades can be used on fine processing, which means it can process some narrow places.
But shape is not the only thing affect the wood processing. Turning tools made up of different materials will also make some differences. Like high-speed steel(HSS) turning tools and tungsten carbide turning tools for woodworking. These two kind of materials have their own advantages. HSS turning tools should run in a lower speed than tungsten carbide woodworking turning tools, but its cheaper. So if your project is made up of some materials with low toughness, buy a HSS turning tools is better than buy a carbide turning tool.
