  Shaping wood, plastic, foam, and other materials by hand can be slow, and ordinary sandpaper often clogs or wears out long before the work is finished. Tungsten carbide tools solve that problem by removing material quickly while staying sharp far longer than steel. A well-chosen carbide burr set gives woodworkers, carvers, model makers, and hobbyists a range of shapes and textures for smoothing, hollowing, and detailing. Knowing what distinguishes one burr from another prevents wasted money and frustration. The sections below explain the main features to compare and how to use them safely. What Makes Carbide Burrs Different Traditional burrs cut with a machined pattern of flutes, while many rotary rasps use individual carbide particles or teeth bonded to a steel core. The hardness of tungsten carbide allows these tools to hold an edge through heavy use, especially on abrasive woods, composites, and resin. Because the teeth are separated by open space, waste clears quickly and th...
