Due to their hardness, solid tungsten carbide drill bits last a lot longer than most other drill bits. Machine shops are used to sharpen these and extend their life. However, any drill bit is going to gradually wear and carbide drill bits are no different. These are particularly useful in mining, construction, and farming due to their longevity. Some drill bits are coated with tungsten carbide rather than being formed entirely from the material. Solid carbide drill bits for hardened steel aren’t always made entirely of tungsten carbide. The Benefits to Carbide Drill BitsĪs previously mentioned, carbide can be recycled which saves money and makes it more environmentally friendly. Carbide recyclers use scrap carbide to create new carbide drill bits.Ĭarbide drill bits are used to drill into the hardest materials, including masonry, but because of brittleness, they are only used in automated production. This premium material comes at a cost but is extremely durable and keeps its sharp edge for longer than most other drill bits.Īs carbide drill bits are not cheap to produce, they are frequently recycled to cut costs. Solid carbide drill bits are often made from tough tungsten, which makes them perfect for drilling. They are used to create holes in conjunction with a drill. What are Solid Carbide Drills Bits?Ĭarbide drill bits are available in many shapes and sizes and have a variety of applications in the manufacturing industry. If additives are not used, the carbide tool will chemically react with ferrous materials and create a crater in the tool. These drill bits are made from grains of tungsten carbide, other material particles, and metal cobalt. As a result, it’s a popular choice for tough jobs.Īnother type of carbide drill bit is known as cemented carbide. This material provides faster cutting speed, more durability, and longevity. This kind of cemented carbide drill bits can obtain accurate hole size increment with self-centering function, so the hole processing precision is very high.Buy Solid Carbide Drill Bits from Drill Bits USAĬarbide drill bits are made from tungsten carbide, a compound of carbon and tungsten. Compared with a welded cemented carbide drill bits, its machining accuracy is almost the same, but because the tooth crown can be changed, it can reduce the processing cost and improve drilling production rate. It is composed of a steel drill body and a replaceable integral cemented carbide tooth crown. The replaceable cemented carbide crown drill bit is a new generation of drilling tools. The cemented carbide drill bits adopt internal cooling method and can be used for machining, CNC lathe or other high-rigidity and high-speed machine tools.Ĥ. Generally, the processed hole has a good degree of finishing, high dimensional accuracy and positioning accuracy, and no follow-up finishing is required. This kind of cemented carbide drill bits adopt self-centering geometric edge type with small cutting force, which can realize chip control of large workpiece materials. The welding cemented carbide drill bits are welded on the steel drill body with a cemented carbide crown. They can be used for lathe and other torsion machining. Cemented carbide drill bits with indexable bladeĬemented carbide drill bits with indexable blades have a wide machining aperture, and the machining depth is 2D~5D (D is the aperture). The self-centering function and strict processing accuracy of the cemented carbide drill bits ensure the quality of the drilling, and there is no need for subsequent trimming after drilling.Ģ. The specially designed geometric edge type enables the drill bit to have a self-centering function, with a good chip control and chip removal function when drilling workpiece materials. In order to extend the service life, coating is also carried out. It is made of fine cemented carbide material. Solide carbide drill bit set is suitable for precursor processing.
