A solid tungsten carbide blade is among the hardest instruments in the world. Thanks to this hardness, it can be used in many applications. Common uses of these blades are found in cutting and shaping materials like metals, wood, and stone. Below are the common types of blades made from tungsten carbide.
Circular saw blades are among the most common blades to be produced with tungsten carbide. It's used to manufacture the cemented carbide tips in these blades for two main reasons. One, the tips provide exceptional wear resistance to the blade, which extends the two blades durability. Two, they maintain a sharp edge for long cutting periods.
Because of the above two reasons, circular saw blades can easily cut through dense materials such as hardwood and construction-grade plywood. More recently, tungsten carbide was also added to router bits for similar reasons.
Planers are used to achieve a very smooth finish on workpieces. However, this fining cut comes at a cost because the blades get worn out very fast. That's why replacing planer blades with tungsten carbide blades is a no-brainer. The carbide blades provide durability and extremely high cutting resistance.
If buyers need to make quick cuts in wood or even metal sheets, jigsaws are perfect for small projects. Luckily, there are jigsaw blades that feature tungsten-carbide grit along their sharp edges. These teeth grits allow the jigsaw blades to cut very abrasive, fragile, and soft materials effortlessly.
The same carbide technology in circular and band saw blades can also be found in reciprocating saw blades. Normally, these blades are used for demolition purposes. Therefore, they are required to have the ability to cut through composite materials, drywall, and PVC piping. That's why most of their tips are embedded with tungsten carbide teeth for extra durability and cutting softness.
Hole saws are used to cut pipe and wood in cylinder shapes. Most of their teeth tips are manufactured with tungsten carbide. It provides maximum cutting ability and wear resistance. Since most hole saws are used for heavy-duty tasks, it's great that they've also been reinforced with carbide.
Thanks to its toughness and durability, tungsten carbide is widely used in making blades for many industries. Below are the most common blade use cases.
Cutting tool blades with tungsten carbide are well-suited for metal cutting and machining operations due to their extreme hardness. Many milling cutters and turning tools are manufactured with carbide blades. It allows them to retain sharp edges even when cutting tough metals such as steel and titanium.
Similarly, in the woodworking industry, tungsten carbide blades are in demand for their longevity and precision cutting ability. Circular saw blades, router bits, and planer knives with carbide tips are ideal for cutting dense hardwoods and plywood. They ensure the blades don't wear down as fast as non-carbide blades do.
For the construction industry, tungsten carbide blades are the go-to solutions for heavy-duty cutting and drilling tasks. These blades are embedded in rotary hammers and coring bits to cut through reinforced concrete, masonry, and other hard construction materials. That's why they are the perfect blades for civil engineering and building projects.
In the mining industry, tungsten carbide blades play a crucial role. That is because they are used in equipment for extracting ores and minerals. Trepanner bits, wear plates, and blades with carbide inserts can easily handle the abrasive and impact forces found underground. This makes them ideal for mining.
Finally, in the aerospace industry, tungsten carbide blades and cutting tools are essential. They are required for machining high-strength alloys used in aircraft and aerospace components. Apart from these blades being extremely hard, they also resist heat. This makes them excellent for precision machining in aerospace applications.
It's a no-brainer that the performance of a carbide tipped bandsaw blade highly depends on the choice of blade buyer makes. Luckily, there are a few factors buyers can keep in mind so they don't have to do so much guesswork when shopping for tungsten carbide blades. Below are these factors.
The quality of the material used to make a blade determines how well it will perform. That's why blades made from premium-quality tungsten carbide composites provide exceptional durability and cutting performance. Prefer blades manufactured with fine-grain carbide for superior strength and edge retention. It ensures smooth and precise cuts. On the other hand, avoid blades with inferior materials. As they are more likely to chip or wear quickly. This will lead to increased downtime from blade replacements, which will directly affect buyers' work productivity.
Blade coatings also play a vital role in enhancing the blade's performance and longevity. For instance, blades with anti-friction coatings reduce drag and heat build-up during cutting. This helps the blade remain as sharp as it was during the first use. Additionally, moisture-resistant or corrosion-resistant coatings are also great. They protect the blade in case it comes into contact with wet or abrasive materials. Settling for blades with advanced coating technology will ensure the blade performs exceptionally for long periods.
The design features of the blade also influence buyers' cutting efficiency. That's why pay attention to attributes like tooth design, gullet size, and kerf width. Ideally, each of these features is intended to serve a purpose. For instance, blades with variable tooth pitches reduce noise and vibration for a smoother cut. Also, tooth shapes are tailored to specific materials. For example, >
ripping teeth are best for cutting wood, while crosscutting teeth give precise cuts on metal. In terms of gullet size, larger gullets are suitable for handling bulky materials. At the same time, smaller gullets provide finer cuts. Finally, a proper kerf width ensures less strain on the motor and equipment. Only settle for blades with optimal design specifications to ensure a reduction in cutting time and efficiency.
Blade compatibility with the equipment or tools buyers plan to use to attach the blade should also be considered. Typically, not all blades will fit into every saw or cutting tool in the market. So, it's vital to select a blade that matches the buyer's tool's speed and power requirements. This will guarantee seamless operation. The good news is that manufacturers do produce blades tailored specifically for certain materials or applications. So, whether for woodworking or metal fabrication, there are blades specifically meant for each project. Moreover, compatible blades reduce wear and tear on both the blade and equipment. It will ensure the buyer's setup runs smoothly and efficiently.
If buyers want to get the best out of their tungsten carbide blades, regular maintenance is key. The good news is that maintenance doesn't have to be resource or time-consuming. Below are some of the easy yet effective blades maintenance and repair tips.
After each use, cleaning the blade is a must. It's recommended to remove any debris, such as wood chips, dust, or resin buildup, from the teeth and edges. The best way to do this is to use a soft brush or cloth together with mild soapy water. Avoid using harsh chemicals. They can damage either the blade's teeth or coating. Afterward, thoroughly rinse and dry the blade to prevent moisture from causing corrosion.
It's no secret that regular inspections go a long way in ensuring the blade performs at its best. During these inspections, users should always check for signs of wear or damage. Look out for things like dullness, chipping, micro fractures, and corrosion. Catching these issues early will help users address them accordingly before they impact cutting performance. In case of minor damages, users can do some repairs themselves. For instance, use a diamond file or wheel to sharpen the edge. But this is just a temporary fix for minor issues like dullness. More serious damages, such as large chips or cracks, will require professionals to recondition or replace the blade.
A proper storage will keep the blade in optimal condition for a long time. When storing the blade, keep it in a dry, protective case or cover to prevent dust, moisture, and accidental damage from occurring. Furthermore, avoid storing the blade in a humid environment. This is because even the slightest amount of humidity can cause rust on either the blade's surface or teeth. If users plan to use multiple blades, their best bet is to store each one separately to avoid them coming into contact with one another. When the blades touch each other, they risk damaging their sharp edges and teeth.
In normal situations, users might finish their cutting task using one blade and then its replacement be on standby. However, it's essential to use the right blade for each task. Using a tungsten carbide blade for a task that should be done using a diamond saw blade will wear down the blade just as beat as it would if it were overworked. So, rotating between different blades for various tasks will reduce excess strain on a single blade. This, in return, will minimize the need for repairs.
