Tungsten Carbide Cutting Tools

The quality of a cutting tool can determine whether cuts will be smooth and clean or difficult and sloppy. A metal cutting tool's quality begins with the hardness and durability of its metal. According to the Society of Manufacturing Engineers, "carbide and carbide-coated tools cut about three to five times faster than high-speed steels" and "higher tungsten content increases wear resistance." There are tungsten carbide cutting tools for a wide variety of applications and, once you understand the breadth of their possible uses, you'll be able to choose one for professional, amateur or even industrial projects.

Circular Saw Blades
Circular blades surrounded by sharp, tungsten carbide-tipped teeth can be found in factories for manufacturing, carpenters' tool kits for milling---and in the home, because do-it-yourselfers can buy them at hardware stores. These circular saw blades are sized to fit not only in industrial machinery but also in standard table saws and hand-held circular saws. The most common tungsten carbide circular saw blades are not solid tungsten carbide; their body is typically tempered steel and only the cutting edges of the teeth are coated with tungsten carbide. A variation of the toothed saw blade is the grinding "wheel" or abrasive blade---still circular but without teeth. Their edge is coated with tungsten carbide and used to exert abrasive force as they grind through stone, ceramics and metal.

Reciprocating Saw Blades
Tungsten carbide coats the edges of blades for reciprocating saws, such as jigsaws and demolition reciprocal saws. The back-and-forth sawing motion of these types of saws is well-suited for abrasion, and their coating of tungsten carbide grit allows them to grind through metals, ceramics and masonry. Applications include removing cast iron pipes and metal fasteners during demolition or cutting access holes through stone and tile during remodeling.

Drill Bit Tools
Drill bits may be solid tungsten carbide or tipped with it to provide the speed, accuracy and wear resistance required by machine shops and high-precision manufacturing applications. Construction professionals and amateurs buy similar bits that attach to hand power drills, drill presses and hobbyist rotary tools. Precision drill bit and grinding tools with tungsten carbide tips might be used for milling or sculpting metal as well as decorative carving of stone and precious gemstones. As materials scientist Dale Wittmer stated in a Southern Illinois University publication, "Tungsten carbide tools have been the standard for over 50 years in the mining industry."
