Using a dirty blade is like shaving with a dirty blade. In both cases, you have to deal with the possibility of more brutal cuts and more bloodshed. Fortunately, cleaning a tungsten blade is as easy as cleaning a razor blade.

Over time, dirt will build up around the cutting edge of the tungsten blade. This effectively covers the edge of the blade, making it look dull. Friction and increased heat make cutting more difficult, and the resulting cut edges are not as clean as they might be. While it may seem counterintuitive, a blunt blade is more dangerous than a sharp one. The blade has the highest cutting efficiency, reducing the pressure on the blade motor. Even if you don’t use it very often, it’s still a good idea to give its blades a quick clean 2 or 3 times a year. Take the opportunity to carefully examine the tip of each tooth on the blade. If many teeth are damaged or blunt, consider grinding them or buying a new one. A tungsten carbide blade can be sharpened (or at least polished) with a triangular metal file. A cemented carbide blade must be sharpened by a professional, but it is usually cheaper to buy a new blade.

Use a solution designed specifically for cleaning tungsten carbide blades. Common oven cleaners may work in the short term, but the active ingredients of the lye can interfere with brazing (the process of attaching a hard alloy tooth to a blade plate), which can loosen the tooth and cause tooth loss during use.

Extra pitch on the blade will shorten its service life. Cleaning the tungsten carbide blade helps extend the blade’s life when the pitch is formed on the tooth. Old frisbees or 5-gallon drum covers can also be used if necessary, as long as they keep the blade flat and in contact with the cleaning solution. For Teflon-coated blades, toothbrushes are better than brass or stainless-steel brushes. The latter two options are good for bare metal blades. To increase the effectiveness of the toothbrush, trim the bristles back to half length. Laminate sample chip is a good choice for scraping asphalt is difficult to scrub clean using a toothbrush method. A handful of sawdust removes residual detergents, and once the asphalt is removed, the tungsten carbide blades shine.

Absolutely not! Carbide is a composite of carbide particles and bonded metals that provides a very hard, long worn material for belt cleaning blades. There are several ways to change the mixture. Some low-cost carbides may also have lower wear resistance, which results in a shorter blade life, which means more downtime is spent on maintenance and cleaning and replacing the tip. Others have poor impact resistance and may chip out another way to cause potential damage zones. In addition, due to poor quality production processes, many tungsten blades tips will be weakened due to voids or binder pools. Ultimately, the cheap price of carbide is not always a bargain, and high-end carbide blades are really worth the investment.
