Brazed tungsten carbide turning tool is a type of commonly used brazed turning tool with high hardness and thus can meet the needs of most of machining materials. Brazed turning tool, as its name implies, is a type of tool in which the blade and the shank are tied  by welding.

 

Brazed tungsten carbide turning tool is simple in structure, easy for manufacture and flexible in use and can be sharpened according to different requirements. It has high stiffness due to its material characteristics. However, it also has its disadvantages, which lie in its relying the cutting properties on the sharpening technology by manpower. In addition to that, its shank cannot be used repeatedly. If the blade is worn or broken, then the shank will also be out of use.

 

Brazed tungsten carbide turning tool, according to its properties and objects, can be divided into three types: the red shank type, the yellow shank type and the blue shank type.

The red shank type is made of YG tungsten carbide, which is represented by YG6 and YG8. It is mainly used in the rough machining of cast iron, non-ferrous metal and non-metallic material. This type of carbide is of high bending resistance but poor abrasion resistance, thus is only suitable for low-speed processing.

The yellow shank type is made of YW tungsten carbide, which is represented by YW1 and YW2 and is mainly used in the semi-finish and finish processing of high-viscosity material like stainless steel. This type of carbide is of high hardness, good abrasion resistance and universality but low bending resistance, thus is only suitable for high-speed feed processing.

The blue shank type is made of YT tungsten carbide, which is represented by YT15 and YT5, and is mainly used in the machining of 45# steel and ordinary steel. This type of tungsten carbide is of high hardness, good abrasion resistance but low bending resistance, thus is suitable for rough processing and semi-finish processing.
