                     What makes tungsten 
carbide the king of 
cutting blades?
 Tungsten carbide blades have revolutionized precision cutting in the world. Its 
unmatched performance is observed and experienced in almost every industry. This 
blade, made primarily of tungsten carbide particles bonded in a metal matrix, marked 
a high water mark in modern technology balancing extreme hardness against 
tremendous toughness.
 Tungsten carbide traces its origin to the early 20th century when researchers searched 
for something harder than steel. A revolution in cutting technology began in 1923 with 
the introduction of the first tungsten carbide cutting tools. As carbide has improved in 
composition as well as manufacturing processes, we have come to use these high-
performance blades.
1. Properties of tungsten carbide blades
 Hardness and toughness: Blades containing tungsten carbide are extremely hard, up to 
9.5 on the Mohs scale when compared to diamond at 10. The hardness is directly 
associated with good abrasion resistance so that blades do not lose their cutting edge 
for as long as any ordinary steel blade could, a scenario where change is made less 
frequently in production, idle time is reduced, and productivity is increased in 
industries.
 Thermal conductivity: Although much less thermally conductive than many metals, 
tungsten carbide’s thermal properties are very suitable in cutting applications. Its 
moderate thermal conductivity helps to dissipate heat generated during the cutting 
process, avoiding overheating of the blade, as well as of the material undergoing cuts. 
This characteristic is especially important at higher-speed cutting operations where the 
buildup of heat can be a problem.
 Chemical resistance: Tungsten carbide is resistant to most chemicals and corrosive 
materials. It is made of this material because it can be used under harsh environments 
or when cutting materials that can react to, or corrode, other blade materials. Acidic 
woods, corrosive metals and many other materials- its blades maintain their integrity 
and performance.
 Edge retention: The most coveted attribute of tungsten carbide knives is edge 
retention. The balance between hardness and toughness allows the knife to retain a 
sharp cutting edge that could easily last much longer than the conventional blades. 
This leads to a generally more consistent cut, lessening the need to resharpen 
repeatedly or replace several times.
2. Applications in various industries
 Metalworking and machining: Tungsten carbide blades are versatile, as there is a 
broad application in metalworking while using hard metals, alloys, or abrasive 
materials. They can be used in milling, turning, and drilling with accuracy and longevity 
at very high manufacturing standards.
 Woodworking and forestry: Tungsten carbide-tipped saw blades and cutting tools are 
used in forestry and woodworking industries as they can easily cut through knots, 
resinous woods, and even wood with small metal objects without blunting as fast as 
traditional blades.
 Plastics and composites processing: Bay Plastics has adopted tungsten carbide blades 
for its cutting operations. They provide superior performance in cutting and shaping 
plastics and composites without melting or deforming the material, enabling the 
manufacture of high-quality plastic components.
 Food processing and packaging: Tungsten carbide blades cut sharper and resist wear 
longer in continuous cutting of abrasive or frozen foods, in addition to resisting 
chemicals and holding up to situations where frequent cleaning or sanitizing is 
required.
 Medical and surgical instruments: Tungsten carbide is used in the medical field due to 
its accuracy and hardness in the production of surgical instruments and other medical 
equipment. Its blades, ranging from scalpels and bone saw blades, possess sharpness 
and dependability majorly needful in medical procedures.
3. Specialized tungsten carbide blades
 Gala die cutting solutions: Gala Die is the leader in specialized tungsten carbide blades 
for the die cutting industry.
 Gala Die blades provide clean, accurate cuts on everything from a few microns to thick 
rubbers with an emphasis on tailored solutions to fulfill the special needs of each 
client. This means manufacturers can fine-tune their cutting process to meet the 
particular requirements of certain materials and applications.
 Maag’s precision cutting technology: Maag’s tungsten carbide blade technology is 
engineered at a high level, targeting large volumes with excellent cut quality, for the 
production of plastics and polymer industries. It specifically deals with pelletizing and 
granulating processes. Its innovations in geometric blade formations and matter 
presence have led to standards for pelletizing and granulating processes.
 Custom-designed blades for specific applications: As the usage of tungsten carbide is 
very flexible, it allows manufacturers to make highly specialized blades for various 
unique cutting tasks. Working closely with blade producers can lead to highly specific 
blades for intricate die-cutting jobs to complex multi-edge blades for highly complex 
cutting operations that require multiple cuts.
 Conclusion
 Tungsten carbide blades come with a lot of advantages in cutting technology, with 
hardness, resistance to wear, and flexibility similar to that offered by traditional 
materials. Their reputation of holding an edge for a long time coupled with an ability to 
withstand severe environments make them highly valued in a wide range of industries.
 From medical instruments that need to be accurate to forestry equipment that must 
be durable, tungsten carbide blades seem to push the barriers of what is possible with 
other cutting technologies. In the future, tungsten carbide blades will play a more 
important role in precision cutting as manufacturing processes change and new 
materials and applications emerge, thus promoting further innovation and efficiency.
