What is a TC Knife Blade?
· TC blades are typically solid tungsten carbide knives or tungsten carbide-tipped blades used in various industrial applications.
· They have a cutting edge made from tungsten carbide, which is significantly harder than steel, providing superior wear resistance and longer service life.
· TC blades can come in various forms, including rotary blades, guillotine blades, sheeter blades, and circular saw blades, often designed for specific machines or cutting tasks.
What is a TC Blade Used For?
· Industrial cutting: TC blades are widely used in woodworking cutter blocks, paper and corrugated cardboard cutting, and sheeter machines in printing industries.
· Metal cutting: Tungsten carbide-tipped (TCT) blades are used for cutting metal such as steel pipes, beams, sheet metal, stainless steel, and other ferrous metals.
· Precision and durability: Their hardness and wear resistance make them ideal for high-speed, high-volume cutting where edge retention and cutting accuracy are critical.
· Materials: They are suitable for cutting wood, paper, textiles, films, foil, and various metals depending on the blade design.
Can You Sharpen TC Knife Blades?
· TC blades are generally considered disposable or replaceable rather than resharpened because tungsten carbide is very hard and brittle.
· However, sharpening is possible but requires specialized equipment or diamond sharpening tools. Typical sharpening methods for steel blades are ineffective on TC.
· Some users sharpen the steel side of a blade that has TC only on one edge, using cardboard or other stropping materials to remove burrs after sharpening the non-TC side.
· There are carbide knife sharpeners designed to reshape or touch up edges on carbide blades, but these are usually for small touch-ups rather than full resharpening.
In summary, a TC knife blade is a tungsten carbide blade used primarily in industrial cutting applications for its exceptional hardness and durability. They are mainly used in woodworking, paper, textile, and metal cutting industries. While TC blades can be sharpened with specialized tools, they are typically replaced rather than resharpened due to the material's brittleness and hardness.
