Tungsten carbide hollow drill, which is called annular cutter when it is used in metal, is a drill specifically designed to remove a cylinder of material, much like a hole saw. Tungsten carbide hollow drill bits are used for many applications, either where the core needs to be preserved, or where drilling can be done more rapidly since much less material needs to be removed than with a standard bit.

Tungsten carbide hollow drills can perform excellent drilling operations on section steels, steel plates, stainless steel and other materials. They are suitable for industries such as steel structures, oil rigs, shipbuilding, bridge engineering, railway construction, machinery manufacturing, factories, and power. Compared with tungsten carbide twist drills, tungsten carbide hollow drill bits are more efficient and cut lightly. Tungsten carbide is an optimal material for fabricating hollow drill bit as the use of tungsten carbide in drill bits provides a longer lasting, stable, and solid material for use in drilling within numerous industries.
